Title: MITAS E07 Tread failure
Post by: ExploreSA on September 21, 2014, 04:39:37 pm
This morning around 9AM we sent off 2x rental GS's and 1 GSA on a trip to East Transvaal

Just when we were readying to go play a round of golf Joe phoned.
 About 80km from when the rentals left the rear Mitas tyre on the GSA delaminated seriously.
 Trudie and I offloaded the golfcart from the trailer and loaded an Anakee tyre in the boot and left to assist them, already waiting at the Petroport on the N12.
 Fortunately the workshop guys at RedStar raceway were present and they could do the swop for us.

The tyres were fitted new on Tuesday and we rode less than 600km on them before handing over to the Clients.

Tyre pressure from the fitting was at 230

But what I am very concerned about is that the tyre was fitted new on Tuesday and has not done more the 700km when this happened. One can see on the closeup the cracks in the tread adjacent to the delamination. The rest of the tyre tread looks ok.

Is this common?

My last gs800adv with 2000km's on them(Tubed)were showing hair line cracks against the Blocks.My last gs800(2013)also showed signs of cracking against the blocks.I love the tyres but it does raise some ? marks.

Bit more info on the ' Renter' maybe ? Topspeed ?  Pillion and panniers ? Not putting blame on the rider , only looking for the real reason with you , as I was/am considering the E07 as my next tire.

My first thoughtwas top speed, but looking at the condition, it seems to be only cracked in that area?

Not good news as I have been on E07s for the last few years. Beside one with the block cracking problem they have been excellent. Hopefully just one bad tyre and not a bad batch.

Interesting. There are a lot of cracks, not only where the failure occurred.
There is an out of the ordinary mark, which I marked in red. I wonder what that is.
Also, doesn't all E07's rear's have the solid strip in the middle? This one doesn't.

went to check mine.. and I also have cracks...

+ - 3000km on them, 100km of dirt,(if that) never seen 150 on the bike (transalp) (usually cruise at 90 -100kmh) and rear is 2.8 as per the transalp owners manual for 2 up.

I have tried to get hold of ktmjedi on roamafrica, but so far I have had no response, so perhaps I luck out here?

Mitas e07
Honda transalp
2.8 rear pressure (rider and passenger)
2. 0 front

Planning an overnight trip with some dirt roads early OCT, so would love to know if this is safe to ride on?

This is very troubling...!
I'm running E07's front and back on my GS  at the moment.
I run them in over some time commuting 12kms to work and 12km back again
before using them on a long trip.
I also run them very hard on tar (250F 290R)
Nothing like this on mine... I hope never!

I do 70km per day on tar, and then what ever I can manage on weekends :) So I need something that will not suddenly fail on me.  (student budget)

Post by: KTMjedi on September 21, 2014, 07:37:07 pm
This is concerning but not something that I have experience before. Small cracks are not a cause or precursor to this kind of failure. This is a delamination and other factors are the cause. We sell 100s of E-07 per month and never had any serious failures to this extent so I believe this is a rarity. I will institute a full investigation into the cause but rest assured that you are safe on your E-07 tyres!
Title: Re: MITAS E07 Tread failure
Post by: KTMjedi on September 21, 2014, 07:46:12 pm
2.3 bar is too low for on road pressure. I am not saying that this was the sole cause but please make sure you run higher pressure to limit heat build up in the tyres. Once again I van assure you that you are very safe on Mitas! 
Title: Re:
Post by: ExploreSA on September 21, 2014, 07:58:44 pm
Any possibility of having the tyre inspected? Where can I sent it to?
The 230 pressure is not accurate. I inflated at a filling station to 260 but the tpm indicated 230. I know my ADV reading is below accurate.
If this may be of use...
Title: Re: MITAS E07 Tread failure
Post by: Flowers on September 21, 2014, 08:21:57 pm
That's rubbish no half decent tyre will delaminates at 2.3 bar.
I once Mita but after that kak explanation my bike will never see mitas!

I believe you may have missed the part where I said that the was not the main cause and was only pointing the low pressure out. I will institute a full investigation and then offer an complete explanation. I hope you will not make your tyre choice based on my quick reply simply trying to make an observation. Mitas is one of the largest Motorcycle Tyre manufacturers in Europe and produce tyres under license for other large brand names based on their quality of products. This is not to say that it's impossible that faulty tyre doesn't happen. I can only try resolve the problem as quickly as possible!

this whole under inflated story sounds like hot air...
I have only used mitas rear tyres on my Africa twin and 950 SE for the last 5 years. I prefer other front tyres. after a few heat cycles my rear never sees more than 2 bar. never really faster than 140 km/h either. have even had it down to 1,2 after just being lazy to inflate after atlantis sessions and rode at a constant 140 for some time. guess what no problems... tyres is great in the tracks out back in atlantis, great on all surfaces and does well on wet roads too as long as it is not over inflated...
so this moerse inflated rear tyre is probably only important if you run top speeds or if your very overloaded???

My last 5 tyres have all been Mitas and never had a second of trouble from any of them.

Currently got an E07 on the back, and the only problem I have is that it lasts too long, Had it on for over a year and the damn thing just won't wear out. Obviously I just don't ride enough.

Proof!!

I mailed Jedi last night with my address and just received a call from him now
- They will collect the tyre today with a replacement
- They will provide a full report after thorough inspection

My intention with this thread was not to break down the Mitas name as I have used similar tyres previously (and over Babboon's Pass), but rather to enquire if others have encountered similar. Which was obviously a negative so far.  :thumleft:

Three of my friends have in the past years encountered delamination with Anakees and the suppliers just turned their heads. My good friend Wahl's rear caused a serious accident to him in so far that he cannot ride anymore due to a back injury because of that accident.

We must remember tyres are made by people and the substance used is a natural rubber. Many things can go wrong and I regard this one failure as a once off.

I will still ride on Mitas in future.

And lastly. Just because Jedi called me so quick means they stand by their product AND their clients

Mitas E010 Front - 7500km
Mitas E07 Rear  - 4000km

Love both of them.  Still early days but that's good mileage so far.

Think this is just a very bad batch. Did 17000kms on mine at 2.3 bar. Rode all over the show and any speed, sometimes even up to 190km/h. Got cracks all over the tyres but never any problems

I have used E07's for years on the rear... never had a problem.

Mark also has used these tyres extensively, and again, never had a problem... and he's usually heavy on tyres!

I'm on my 5th set of E07's. The previous 4 all got 15,000km or more.

Very happy with their all-round performance as I commute year round and do 1 or 2 weekend off-road trips each month. Have done Lesotho and recently Transkei as well.

For me the E07s is a good compromise (balance between performance/grip and km) tire.

Hi All, thank you for allowing us to examine the tyre and report back ASAP. Replacement tyre has been dispatched and the damaged tyre will be collected for inspection. Once I know more I will let all know. I can confirm that this is a very isolated case, I called Mitas and asked if they have had any other reports of similar failures and thankfully not.

also ripped some knobblies out of mine (on a previous thread). but I got my mileage out of it first so wasnt to concerned. They also refunded some which shows good backing. Will support them again.

Mine started of early with cracks, riding loaded with pillion, slowly progressed and worsened but I wasn worried to much. then on my final 300km actually to replace them I did a 200kmph stint and found some knoblies lost the day after.

Couple things here!

@Exsa

Was the tyre still inflated after the delamination? and if so what was its pressure?

@ some of the above posts

I find it concerning that some people jump in as judge and executioner, some even saying they will never buy them without even trying them. Others just calling them kak! this all before the importer has commented or inspected. Darren will sort this out and I think it shows in his willingness to send a new replacement before a inspection is done. This for one gives me confidence in this product. These are race pedigree tyres. Please note my above statement is not at Exsa but at those sheep in the grandstand who start baa ing at a unresolved issue without hearing both sides. Is this the dictatorship mentality we want, if so we here are doomed. I wonder how many of these people will man up and say sorry?

I have seen delamination on many brands from Heidenau's to mitchelins some on my bikes and some on others and believe me ALMOST always there is a external reason. Such as

1. under inflation
2. over inflation
3. unrecognized puncture
4. overloading
5. extended high speed with one of the above problems
6. impacts
7. manufacture fault. (if this happens its usually a batch fault)

there are a few more that dont come to mind

Die solid strip is darem heelwat smaller as die Heidi sin, ek het een op en het nou so 3000 km gedoen en jy kom nie eers die strip agter nie, traksie is nog steeds goed en beter as die Heidi op 'n reguit lyn, die Heidi se harde compound en breë strip maak dat hy amper geen traksie op 'n reguit lyn het nie.

Three of us have just done a combined 20 000km on three E 07 rears and two E 10 fronts through Bots and Nam. One bike showed unusual wear after 4000km on the rear, cause was agreed to be the 4 Bar that he was inadvertently using after fitment.

For what it's worth I believe it to be an isolated case. Also, the yellow stripe indicates the extra layer of ply "Dakar" spec issue whilst the new standard design has the centre ridge.

I Agree.

I had a 130 on a 950 SE and I naaied it everywhere. I could not break it and that tire was not even designed for the 950. I always inflated to 2.8bar.

Check the date on the tire, It could be old, also any un-inflated tire at speed will put you in a coffin quick quick.

Without hi-jacking your thread, you are lucky to receive such special treatment.    :thumleft:  I am still waiting for the promised replacement for my mitas E07 that cracked severely and eventually lost a chunk on our way back from the XT bash at Koedoeskloof.  I reported the matter on the 25th of August already and still waiting.  Hope to receive it soon, I am beginning to get withdrawal symptoms from not riding the S10.  ???

We must remember tyres are made by people and the substance used is a natural rubber. Many things can go wrong and I regard this one failure as a once off.

I will still ride on Mitas in future.

And lastly. Just because Jedi called me so quick means they stand by their product AND their clients

Without hi-jacking your thread, you are lucky to receive such special treatment.    :thumleft:  I am still waiting for the promised replacement for my mitas E07 that cracked severely and eventually lost a chunk on our way back from the XT bash at Koedoeskloof.  I reported the matter on the 25th of August already and still waiting.  Hope to receive it soon, I am beginning to get withdrawal symptoms from not riding the S10.  ???   
please will you PM me your details as I am sure that all outstanding claims have been settled. If yours is still outstanding I need to look into asap! Please note that we mostly deal directly with the reseller an either replace the tyre or credit the account. Please give me your details and I will look into it. Please keep in mind this situation is a little different with GS rentals are technically a reseller so I am able to deal directly with them.

Couple things here!

@Exsa

Was the tyre still inflated after the delamination? and if so what was its pressure?

@ some of the above posts

I find it concerning that some people jump in as judge and executioner, some even saying they will never buy them without even trying them. Others just calling them kak! this all before the importer has commented or inspected. Darren will sort this out and I think it shows in his willingness to send a new replacement before a inspection is done. This for one gives me confidence in this product. These are race pedigree tyres. Please note my above statement is not at Exsa but at those sheep in the grandstand who start baa ing at a unresolved issue without hearing both sides. Is this the dictatorship mentality we want, if so we here are doomed. I wonder how many of these people will man up and say sorry?

I have seen delamination on many brands from Heidenau's to mitchelins some on my bikes and some on others and believe me ALMOST always there is a external reason. Such as

1. under inflation
2. over inflation
3. unrecognized puncture
4. overloading
5. extended high speed with one of the above problems
6. impacts
7. manufacture fault. (if this happens its usually a batch fault)

there are a few more that dont come to mind









Well said T Jockey.

There are so many "experts" here I feel totally inadequate and hopelessly outgunned

You guys are so awesome you must get jealous of yourselves

I have done about 50 000 km on a few E07s on an 800GS and SE - fast, slow, rocks, sand, tar, gravel, snow etc - I get great mileage (10 000 km plus out of a rear tyre) and regularly see little hairline cracks but that does not bother me - you will always get that on any type of semi knobbly tyre - especially on 4X4s

The key to any tyre (no matter what vehicle it is on) is pressure - too low and the tyre will self destruct.

I have several vehicles with tyres on (cars, bakkies, land rovers, off road motorbikes, road motorbikes and bicycles ) - I do not use every vehicle every day so I make a point of checking tyre pressures with my own gauge almost every time I use each vehicle - and if the pressure is too low I pump it up with my own compressor and tyre inflator at home - for those who do not have these tools go and buy yourself a decent tyre pressure gauge at Midas etc for less than R100 and check your vehicles with this - the gauges at the petrol stations are hopelessly inaccurate - so after you inflate with petrol station inflator check the pressure on your own gauge.

If you are unsure of what is the correct pressure for you then pump it 10% harder than what the "book" says - your tyres will last longer

Check your tyre regularly for any cuts / cracks / screws / nails / punctures / leaking valves / etc - these can almost all be repaired with plugs etc for very cheap and save your tyres and possibly your life - all it takes is some time and effort

Please do this before you come on to a public forum and voice your "expert" opinion on how shit you think a certain tyre is

Thanks for the reply.

IMHO opinion that leaves two options UNDER INFLATION / OVERLOADING or Factory fault. Check for hairline stress lines and signs of overheating that will indicate under inflation or overloading for the amount of pressure in the tyre.

I was told that you get the E 07 with two different compounds........One soft for offroad only and the other harder for DS type riding...?

Different colour strips or something.............Is this true Ktm Jedi ?

My E 07's have performed admirably......... lasted long and lekker grip. Front 2.6 and rear 2.8 ....all the time ( except offroad) and no cracks at all with pillion 50% of the time.

Tyre Pressure

The "230" pressure seams to get quite a lot of attention.

As I mentioned before the TPM on the Adventure is not accurate and tends to read low, if I remember correctly.
When the bike returns this weekend I will check the difference with my VDO handheld meter. This may sort the discrepancy.


Overloading

Then there is mention of overloading. What is the tyre limit on an Adventure? Is it at all possible to overload?

(For interest sake check the Tare and GVM on your GS licence disc. In most cases it is overloaded with one person on!
The present GS on the stoep:
Tare: 229
GVM: 304

With only myself on dressed in a jockey alone it is overloaded!!!  :imaposer: :imaposer: :ricky:

Although it is very difficult to match the conditions such as road, load and speed. But the tyre pressure must always match the load and conditions otherwise particularly at high speed there will be failures. On tar I always run at max pressure. Please dont ask about off road.  ;D

My tyre never sees 2.8 bar. This is actually very easy for me. If i get on the bike with no kit, i am over the weight limit, let me find another tyre.

This 328kg (on my tyre 325kg) is obviously on the one single tyre, meaning one can load in excess of 550kg GVM on the bike.

I weigh 117 (En ek is nie vet nie) Pillion 76, Adv about 360, Luggage on a long trip about 50kg = 603kg

Then overloading can just about NEVER be a factor in consideration.

Just a point about max weight. This is based on max weight and max speed rating. i.e you need to be over 328 kgs (656kgs on both) per tyre at a sustained speed of 190km/h!

Which is practically impossible under normal riding conditions.

The factory engineers have the details and I am just waiting for the tyre for some additional information and details. They have also put a tyre from this batch on stress test to see if there was a batch problem. IMHO this was a simple dud tyre and something that happens every now and then. Even in F1 where tyres are x-rayed and hand built to the highest specs a dud will creep through. I suppose its like baking a cake...you can follow the recipe to the T and you will still get that flop 1 out of 100. Don't get me wrong this doesn't excuse anything and at this stage just my guess.

Not an isolated incident and not blown out of proportion.  I think we have the right to known what is the cause of this and if there might be a problem with the batch.  That is then also precise what KTMJedi is doing and kudus to him for that.  Once we know the outcome we all will be at ease.  Surely you do not want something like this to happen to you while doing 120 + in a corner with a pillion on the back or on a remote trip somewhere in Namibia with help days away.  Our safety is at risk if there is a problem with the tyres.  We just want honest and true answers, and I think we will get it from the suppliers.

Very interesting Fred this!

I put an E07 on recently as there was no stock of Scorpions and I was going up and into Lesotho. Have no regrets so far and am loving it! There are a few small chunks out of it, but that's from pulling the ring out of it offroad! ;-)

Did I read correctly earlier in this thread about running or 'curing' a tyre in? I know about the first 50kms or so and scrubbing  any new tyre, but if I recall correctly, someone was talking about getting it up to temp and running  it in?

Or am I PUI???  ???

JD hit it right on the head. Well put. I removed/destroyed the Knobblies on a TKC80 simply from ridding the rear under-inflated. I didn't blame Conti...it was my own doffness.

Daar is fokkol fout met die tyres nie of miskien ry ek soos 'n girl. I did the heat cycle thing and checked for cracks regularly because of the life threatening publicity this received and nothing. I have done 16000km on my current set with the rear at 30% and the front 5% threat left. (60% gravel) I have abused my front tyre one day we had an advanced training day at the track and is of the view that it might have lasted longer if not for that. Running them at 2.8bar on tar and 2.2bar on gravel. I would like however changing to the Mitas Dakar like the tyre under discussion when I change.

Which is practically impossible under normal riding conditions.

Meaning overload discussions is a waste of energy.

Yes and no

Yes if the pressure is correct.

No if you have not taken the load in consideration. So once again its about pressure. But must be looked at as a whole with the consideration points of load then speed and finally pressure relating to the first two point the greater the first two the higher the pressure. Make sense?

Pleasure...I am just waiting for a result on the tyre analysis...Only problem is to get a definitive they want the tyre back to Europe for lab analysis. However I am due to discuss the issue with the head of quality control and the head of Manufacturing and we can hopefully speed up the process in getting a answer as to the cause of the failure.

I bought a BMW F800 Adventure with Mitas front and back tyre already fitted. The bike has done about 500km with the tyres.
We went to the Hell & Baviaanskloof for a long weekend. I had the first flat tyre at Mooreesburg. We stop at a tyre fitment centre where the guys pulled the tyre of the rim and saw that it had a tear in the side wall of about 50MM.
Having no other choice they repaired the tyre with a patch on the inside and also the tube. We then left for Sutherland via the Tankwa Karoo stall which burnt down the next day.
Long story short the tyre started losing pressure again at Willowmore. (Rony AKA Malletjie) from Jumpers helped us out on Sunday with a secondhand tyre (Not Mitas) and a brand new tube. I was very greatfull! Everybody can definetely pop in there. We had cold beers afterwards and was on our way. Thanks again to him. To get back to the topic. The Mitas rear tyre had 2 extra tears in the side wall on totally different places. We left the tyre with him.
I have got no idea why this would happen?

This is my new one. Received today. My E10 is murtu in less than 3,000km.
Am I correct that the E07 that delaminate did/do not have this "centre ridge"?

Sidewall....but what I can't understand is the F800 has a tube so even if the tyre split for some reason (a failure I have never seen before) it would not have effected the tube. The only way you can get a cut in the sidewall and the tube is something cut the tyre and the tube. With regards to the other flat that I would need to investigate further and if you have details of where the tyre is I would like to check?

Side wall failure  ::)  Generally Mitas E07 and E09's are known for strong sidewalls in my experience. Inevitably you will have hit sharp rocks hard … possibly with tyres that could have been over inflated for the conditions … Tankwa has some of the most abrasive rocks around  :eek7:

I went through two E07's on my Transalp. The first one started cracking and tearing at 500km's and the second one of the new compound tyres only lasted a little longer before it also started with the same problem. After complaining I was accused of not riding the tyres  in and the wrong tyre pressures. I'm now back on my second set of Bridgestones again, a tyre that that you can basically ride at any normal pressure with any acceptable weight  at any speed possible for the Transalp without any worries that something will go wrong.

The EO7 with the yellow stripe is the Dakar version and is said to be pretty much a " run flat" so I wouldnt think that that is the problem. Has anyone googled the specs and blurb regarding these tires.

Also? When did we stop spelling tires tyres? ? :pot:

Just a point on this, once you have added freight, labor and VAT R755 is below cost so think whoever at Bike zone quoted you that is in trouble.

We can now accept the failed tyre's pressure was at 245 minimum.

Unfortunately due to the serious nature of the failure Mitas wants the tyre back for lab analysis which is going to take time for an official report. HOWEVER in discussions between myself and the engineers at Mitas we suspect a delamination failure.....in basic terms the glue didn't stick so lekker. A tyre is made up of 3 textile plies which forms the carcass of the tyre and then you have the tread layer which is glued (vulcanized) to the textile ply. this bonding between the tread layer and textile ply failed. The question is why. There are a few ways this can happen heat build up being the main cause but it doesn't seem so as I cannot see any signs of this. Due to this my suspicion is that the weak bond occurred in the manufacturing process. Good news is that stress tests from this batch didn't reveal any batch issues. I will follow up with the factory for a definitive answer ASAP!

Was tentatively waiting for feedback on this but couldn't wait any longer so decided to go ahead and get one. Had it fitted earlier by Just Bike Tyre in Centurion, not to scrub it in a little and find some dirt.
Unfortunately due to the serious nature of the failure Mitas wants the tyre back for lab analysis which is going to take time for an official report. HOWEVER in discussions between myself and the engineers at Mitas we suspect a delamination failure.....in basic terms the glue didn't stick so lekker. A tyre is made up of 3 textile plies which forms the carcass of the tyre and then you have the tread layer which is glued (vulcanized) to the textile ply. this bonding between the tread layer and textile ply failed. The question is why. There are a few ways this can happen heat build up being the main cause but it doesn't seem so as I cannot see any signs of this. Due to this my suspicion is that the weak bond occurred in the manufacturing process. Good news is that stress tests from this batch didn't reveal any batch issues.

Mr Jedi, I haven't had the pleasure of trying some of your tyres (yet), but I certainly cannot think of any other supplier/importer going to the lengths that you do to follow up and support your product.  Well done!  You are a shining example to most industries in SA.  May your business success reflect this fantastic attitude!   :thumleft:

Agreed. Even with this nasty failure just the fact that KTMJedi is so involved and wants to find the reason and give feedback was enough for me to go ahead and fit one. So far I love it, only a few hundred KM but just that fact that is round and not super squared like my last tyre is a huge improvement lol. Looking forward to taking it off the tar soon

I think the bottom line is I cannot guarantee you will never have a failure, no one can. If even at the panicle of tyre development and performance, Moto GP and F1 they have failures, then the reality is that Mitas... or anyone else for that matter, will never be able to produce a tyre that is 100% "fail proof" ! I suppose it comes down to how you deal with it that counts?
Having said that...hell some claims that come thou  ::). cuts from rocks and other hair line cracks are deemed a claim  :o. Well lets see if I can keep everyone happy  :thumleft:. Many happy and safe miles to you all!

Agreed, that's why it didn't put me off buying the tyre (and it wasn't my only option or consideration in all honesty). The rare failure is something that occurs to just about any product in any industry, what's important (to me at least) is how it's dealt with and resolved... That is what either wins customers over or, more importantly I think, keeps existing clients from changing to another product/brand/type, etc.

Mitas e 07 are great tyres I used two sets on my previous GS and GSA. One day I noticed a few smal cracks on the tyre, I did not bother about it until it started leaking air, then I contacted the supplier, the lady was very friendly and told me to go to the dealer and swop the tyre. Before going to the dealer, I went to a colleague, which is an expert on failure analysis, he told me the perceived cracks were caused by a sharp foreign object, I immediately called the supplier and told them there are nothing wrong with the tyre, it was my fault and I replaced the tyre at my own cost.

The point is, how many people claim tyre failure, while it was not actually failure of the tyre.

Fantastic tyre up to 650 class imo. Have run them on my Husky 610 lots. Many long trips including tar - Lesotho twice etc. Very tough. Run it in nicely and lasts fine … yes probably not 8000km but then this is a proper knobbly.

I was thinking about this whole debate last night. Heat cycling the tyres, correct pressures etc.
I was just wondering, why doesn't Mitas (or any other tyre manufacturer) give out a pamphlet with their tyres? The typical biker walks into a shop, listen to what the shop has to say and fits the tyre. There is no packaging material or owners manual or anything to go with it. Usually the shops just tell the customer " take it easy for the first 300 km, the release agent makes them slippery"
If the customer follows his bike's owners manual, he might not be running the correct pressure.

I only found out about heat cycles a year after I fitted my tyre.

The reason is very simple , a particular tyre will require different pressures depending on the bike it is used on . The manufacturers supply the distributors with catalogs which will list the tyre pressure per bike and tyre .
As far as riding in , that is up to the sales person to inform the client , but the riding in period is just a few km , definitely not 300km , usually less than 50km , I personally do it in the first 10km , the idea being to ride gently , almost like riding in the rain .

On a serious note, I'm on my very first set of Mitas and after 2500km there's no problem. Even if I get problems with it, I will continue using the brand for as long as there is this genuine support for the product. I'm done with suppliers and brands that are just watching the bottom line, to hell with the customer. Well done Mr. Jedi.

2.3 bar is too low for on road pressure. I am not saying that this was the sole cause but please make sure you run higher pressure to limit heat build up in the tyres. Once again I van assure you that you are very safe on Mitas! 

This is a first I have seen or heard.  I run E07s and my last one lasted 30,000kms.  It had many cracks but gave me good mileage.

I think this one was just one bad apple in the whole lot.

I run EO7's on both my 800GS and 1200GS. Fantastic ! (even in the RAIN!!) However, these tyres are NOT suitable for speeds of 140 PLUS. 

Sub 140km/hr and 2.8Bar Front, 2.5 Bar (Both bikes) and I get average 14 000km on the rear and about 25 000k on the front.

This bad delamination looks to me like sub-sonic speed, load, and under-inflation is the culprit !

your front is not a 21 inch. As I have seen it, only the E07 90/90/21 is a tube tyre. I know a few people running the 21 inch on a tubless setup without shit so far.

En dan wat maak ek met die tyre wat sover 10km gery het???   >:D


Ek worry nie oor presure verloor nie. Wat is die ander gevaar?
Yes sorry take it off! The E-10 is tubeless not the E-07. I understand what you are saying but as Mitas I need to tell you its the wrong tyre! Danger....if you do have a flat and an accident as a result. You run the risk of a cleaver assessor noticing this and denying the claim  :-\. Ultimately this is your call ! 

And on all the GS/GSA's , should we all take them off ?

No the 110/80-19 tyres are tubeless. ONLY the 90/90-21 Mitas E-07 tyres are TT. If you are ever unsure check the sidewall of your tyres it will tell you if it's TT or TL! Once again only the 90/90-21 Mitas E-07 front tyre it a tube type tyre, the 110/80-19 fronts and rears are tubeless!

Eish...you have to be SO careful what you say on line. We are talking about a 90/90-21 fitted to a KTM 1190 which has tubeless rims. I say that this Mitas tyre is not Tubeless and then suddenly all Mitas tyres are not tubeless. My fault I should be more specific! If you are ever unsure check the side wall for the markings ! TT stands for tube tyre (it will also have "Tube type tyre" on the sidewall!) TL stands for Tubeless tyre and yes you can also fit a tube to a Tubeless tyre  ;).

Please take the E-07 front as it is not Tubeless...not sure who fitted it but you will probably loose pressure with it![/qoute]

Sheesh!? Really?! The okes that fitted my E10 front without a tube!?

On the Mitas website is the following: "All sizes will be available only as tubeless and in category T (speeds of up to 190 km/h)."

You could also drop your pressure which will bring your tyre temp up thereby improving your wet grip.

Did 1300km this weekend with my E07 tube 21" tyre on tubeliss rims on the 1190.

Did not loose pressure in 8 days.

Awesome on dirt, point and shoot, grips all the way.

But I did get front wheel slip on tar in the twisties. Happened twice :o

Was over 200kph plus some VAT  :thumleft:

Yes, I know its over the speed rating of the tyre  :thumleft:

TBH I am also not happy with the situation. However there have been a few factors that have delayed the process. Firstly Mitas Bought Sava and they where both working on their own versions and management put a hold on it until the merger took place and the teams where "joined" . then in all their wisdom  :o decided to develop their super sport tyres first  ???. They have also subsequently decided that the Sava Factory concentrate on the more on road tyres and scooter tyres and Mitas the more off-road bias tyres....this meant moving the factory around etc ...delays  :-[. The up-short is we have about 5 or 6 new tyres next year with good stuff to come after that as well. Its taken some time but when in swing we will be rocking!

After reading this post I've checked my rear EO7 and I've also noticed small cracks on the top of the knobbly, I'm sure it will be ok! My tyre pressure is 2.8 in the rear as I was two up and had 12kgs luggage on the rear. I did some dirt today but never dropped the pressure as I had a lot of tar to do after the dirt.
I have maybe 2000 Kim's on them and I run the EO8 in the front. All I want to know is should I worry or not?

I have done about 5k km on my rear e-07 on the 1190. It looks much worse than yours, and I abuse my tyres a bit. I can spin through first and second on tar so there are chunks torn out of the tread but it hasnt given me any problems. Probably about 2mm tread left before it becomes illegal.

I run mine at 3.2 bar always, mostly to protect the rims.

Mine also started like that and progressively deteriorated.  Keep a close eye on them tyres.  I was also told not to worry until I lost a chunck in a long sweeping bend at about 130km/h.   :eek7:  I almost lost it but managed to save the situation, but it could have been much worse. 

They are great tyres, but once they start to crack I have no trust in them.

I agree with Vis Arend, it is great tyres till they start cracking. Mine also started with the small cracks during a trip and became worse as we continued till the re-inforcing was visible through the cracks. I replaced it in Cape Town as I was not prepared to risk my life on tyres cracking up. Mine had about 3500Km when I replaced it. No trust in Mitas anymore.

Dit is maar 'n moeilike storie,

Ek hou baie van die E 07's en het al 'n paar stelle op gery, so ook twee van die nuwe compound, op my eerste stel van die nuwe compound was daar geen snaakse kraake, my tweede stel het snaakse kraake gewys in die omgewing van 3/4000 km, ek het hulle af gehaal en vervang met Karoo 3's wat 'n baie lekker band is maar die agter band gee nie km's nie.

Nou sit ek met die probleem,

Heidenhua gee km's maar is 'n k@k band wat grip aan betref,

E 07's kraak en maak dat ek hulle nie meer op 'n lang trip vertrou nie,  

Karoo 3 is great maar ek kry net 3000/3500 km op 'n agter band, die voorband lyk of hy goed gaan hou en hanteer lekker met baie grip.

So wat moet ek nou op sit, ek wil nie road base gaan nie en TKC's gee ook nie km's, Karoo 3 is nice voor maar dan sal ek iets anders agter moet op sit om die km's te regverdig.

Opsie wat ek aan gedink is om maar 'n Heidenhua agter op te sit en met  minder grip saam te leef en 'n Karoo 3 voor te hardloop wat weer lekker grip het.

Overloaded

When we together next time we can debate this. It has been done to death already on this forum. Please look at the sidewall on all tyres and note the load and speed indexes (they are basically the same on all tyres).

http://www.blackcircles.com/general/speedrating (http://www.blackcircles.com/general/speedrating)


it is on all tyres including car tyres. The link above explains

Saying a tyre is KAK because we push it past its boundaries is just not cricket.

I am assuming you where overloaded by your description, we dont know as nothing was weighed, but its easy to overload a tyre causing too much flex even at 3 bar and that causes overheating.

Don't get me wrong, I don't say the E 07's is kak, I actually like them it is only the cracks that make me worry about them

But if overloading is the problem, why does the other tyre brands dont show the same type of cracks under the same conditions and loads , as you said the weight spec are very much the same on different brands  ?

The E07 appears to be rated for 325kg and 190km/h - from the description I would hardly call that pushing the boundaries...

Thanks TJ, would like to hear your explanation on this.    :thumleft:

For interest sake, I see here below that GRIM says the rating is 325kg.  That is where my problem is.  The bike already weighs in at say 250, plus me pusses the load to 350, that without pillion and luggage.   :eek7:  There I am over the rating.   :o  ???   If this is the case they are selling me a tyre that's not up for the task.  In any case, who the fuck rides a 250kg monster that weight only 75kg.   :eek7:   :lol8:   

I specifically asked the question on this forum hoping to get a straight answer.   If I can recall correctly it was said that the total load of the front and rear must be taken into consideration to determine the load.  If that is the case, I was not overloaded.
I agree with you on this topic, "Saying a tyre is KAK because we push it past its boundaries is just not cricket", but if I load and ride it within it's limits, and it still cracks up, it is a kak tyre, in my opinion in any case.   :deal:
As Jakkals says and as I mentioned, its a great tyre, but it's cracking me up man.    :imaposer:

I dunno about Man from Nam's bike tyre, but mine looked a lot worse and that was from running on tar for 700km, tyre inflated to 3bar, speed between 120-140km/h with a pillion and loaded for a 4 week holiday in tempratures around the 30, stopping every 100km or so for a smoke break. 
If a tyre can't handle that, it is a kak tyre.   :deal: 

Overloaded

When we together next time we can debate this. It has been done to death already on this forum. Please look at the sidewall on all tyres and note the load and speed indexes (they are basically the same on all tyres).

it is on all tyres including car tyres. The link above explains

Saying a tyre is KAK because we push it past its boundaries is just not cricket.

I am assuming you where overloaded by your description, we dont know as nothing was weighed, but its easy to overload a tyre causing too much flex even at 3 bar and that causes overheating.



Thanks TJ, would like to hear your explanation on this.    :thumleft:

For interest sake, I see here below that GRIM says the rating is 325kg.  That is where my problem is.  The bike already weighs in at say 250, plus me pusses the load to 350, that without pillion and luggage.   :eek7:  There I am over the rating.   :o  ???   If this is the case they are selling me a tyre that's not up for the task.  In any case, who the fuck rides a 250kg monster that weight only 75kg.   :eek7:   :lol8:   

I specifically asked the question on this forum hoping to get a straight answer.   If I can recall correctly it was said that the total load of the front and rear must be taken into consideration to determine the load.  If that is the case, I was not overloaded.
I agree with you on this topic, "Saying a tyre is KAK because we push it past its boundaries is just not cricket", but if I load and ride it within it's limits, and it still cracks up, it is a kak tyre, in my opinion in any case.   :deal:
As Jakkals says and as I mentioned, its a great tyre, but it's cracking me up man.    :imaposer:

Sien in jou link hierbo het jy reeds raakgelees dat die load rating per wiel/band is. Dis hoe ek dit ook het.
Maw as jou bike se nou maar 450 weeg met pillion en bagasie is dit 225kg per band vir 50/50 gewig verdeling op altwee wiele wat ver binne die 325kg op die agterband is.

Personally don't subscribe to the excuse of overloading and low pressure.
I have done loaded travel at speed up to about 160 on 1 bar pressure with no problems on other tyres.
Yes you get tyre failures with speeds close to speed rating and lowish pressure and/or very low pressure such as a puncture combined with high speed but that does not imply every tyre failure is due to overloading and high speed.

Exactly, too low pressure increases tyre flex which affects the structural integrity of the tyre which also affects heat build up. On a ride you will see a lot of guys airing their tires down for gravel,but few re inflating once you hit the tar again.

The tyre manufacturers should then provide a warning statement when the tyre is purchased alerting the purchaser of the dangers of inter alia tyre delamination due to insufficient tyre pressure etc. If they don't it would seem to be a stretch of the imagination to think the purchasers would be aware of tyre deficiencies which are not in the normal realm of expected tyre issues.

tyres at the best of times are a compromise. You gotta give a little in one area to benefit in another. I think tyre manufacturers are struggling to keep up with the big bikes.
You got bikes,like yours,making close to super bike power,but then you want a 50/50 tyre to enjoy your bike .
We all know what it is like heading home on a Sunday after a weekend away,we mostly end up caning it to get home. Sometimes the tyre scare not as hard as the beginning of the weekend,and I feel this is where most damage occurs.

So I might be missing the a couple of facts or comments as I just skimmed over this thread, but there is one very important bit of info every bike tyre buyer needs to know. SPEED RATINGS & LOAD INDEX's on tyres are the most crucial bit of info you need to understand when buying a bike tyre. Each tyre should be clearly marked with its speed rating and load index, normally with the tyre size, for example : 150/70/17 69V. The 69V is the load rating and speed index code; i.e: 69 = up to 325kg's and V = maximum speed of 240kmh continuous speed. So if your bike is rated for a 69V tyre don't go fitting a 64S (280kg/180kmh) or 54R (212kg/170kmh) or etc because it is a couple of bucks cheaper, delaminating will be the least of your worries, the tyre could let go completely and put you in a world of hurt. Always try to fit the same or better than what your bike is spec'd for. A simple guide is to remember that both the load index and speed rating code work in ascending order, so the higher the number the higher the load rating and the furhter down the alphabet, the higher the speed rating. So if your bike is spec'd for a 69V and the dealer only has a choice of a  64S or  a 73W, take the 73W (365kg/270kmh). Compounds and tread patterns are secondary to load index & speed rating.

I have run a E-07 for the last 5000km on my 1190 R. I ride hard, hard acceleration and hard braking on and off the road.

I have taken it up to 200 for very short moments when overtaking or playing with the "fast" cars, but never more than six seconds at a time. I have broken traction on the roads often when accelerating and have backed the bike into corners. I have small chunks chipped off the tire, but absolutely no cracks at all. I never ever deflate my tires from around 3.1 bar, I have not loaded the bike with the E-07 nor have I done days over 400km of tar with it.

I am very happy with the tire wear and performance, except for riding in the rain. In the rain this tire scares me.

I dont think its power or riding style that causes the cracks, or perhaps mine was made on a good day?
Title: Re: MITAS E07 Tread failure
Post by: Bensien on August 04, 2015, 06:24:38 am
When it comes to adventure bike tyres with aggressive treads, speed ratings are largely academic. There is a vast difference between running a tyre on the autobahn or against a drum in the factory, compared to our rough potholed roads, gravel and a variety of off road surfaces. These surfaces gradually weaken the tyre carcass. If you regularly ride your bike off the highway, limit your maximum speed when on it or on good secondary tarred roads. The bike manufacturers all have warnings in the manuals to restrict maximum speed to 160 when using knobbly type tyres and if you look at a TKC80 meant for heavy bikes, you will see it has a Q rating (160 kph)

Aggressive tread blocks also flex more, causing the tyre to work harden in the areas of flex, which leads to cracking. The likelihood of it happening increases with low pressures, high loads and continuous high speeds. Also bear in mind that if you ever had a puncture, regardless of whether you use a tubeless tyre or not, the tyre is damaged and all manufacturers’ warranties fall away, as well as speed and road ratings.

One last thing about speed ratings. The rating indicates sustained maximum speed. That does not mean running indefinitely at that speed. It means 10 minutes.

You should maybe also mention the fitment of wider tires.
A tire is supposed to be matched with a specific width rim. You should NOT fit a wider tire just because it looks cool.
OEM tire sizes are often border line (read: already too wide for the rim size) and fitting a wider tire does not only cause wheel clearance issues but also forces the tire into an unnatural shape which will result in different flex of the carcass and thereby might affect the speed rating and load capacity.

With regards to wheel clearance: Minimum side wall clearance is some 6mm (check with a pencil) at any place through the suspension travel. Thread to chassis clearance on a DS bike should be 2cm or more (check with finger).

You must be American by birth.

If you are going to use anything or you research and learn. No one will use heavy machinery with out training. Your bike is no different. You bike more than likely came out with another brand of tyre. If you change it do your homework. You cannot blame the tyre or the manufacturer for abuse, intended or unintended. Bottom line its your responsibility.

@ cocky yes its the same as cars and the tyre is rated at maximum constant speed and maximum weight at maximum pressure. And thats the kicker its up to us to be able to judge the conditions in relation to our speed in relation to the load in relation to the pressure.

Anyone can destroy any tyre in a very short space of time if the above is not close to right

One thing I do agree on is that I feel that all DS tyres are not weight rated high enough. IMHO.

One last thing about speed ratings. The rating indicates sustained maximum speed. That does not mean running indefinitely at that speed. It means 10 minutes.


The rating indicates MAXIMUM SPEED AT NAX LOAD pumped rock hard ON A STANDARD SURFACE (which is EN or DOT smooth) at a standard temperature (which most likely is NOT African hot).
It does NOT indicate maximum sustained speed at or near the max. rated load on a bad road on a hot Kalahari day.

You have to deduct a considerable safety margin from the rated max. speed if you run the tire at the speed all day or if you run it close to or at the max rated load. Same for running the tire on bad tar or gravel vs. good smooth tar.

As a wild guess based recommendation  I would say don't exceed 80% of the speed and load rating of a tire.

What some also do not realise is a tyre can be damaged/compromised early in its life and often only manifest later. Just because that one time you naaied it back from Pitsonderwater after a day in the dunes and it looked just fine on the outside does not necessarily mean that all is OK with the compound, carcass integrity, sidewall plys  etc  ::)

Katana I agree with your post entirely, but I did abuse my E-07 and it doesnt have any cracks. So I think its inconsistent quality from the factory?

I agree.  There is that pattern.  The 150/17 is a big bike tire though.  (Same as the 150/18)

This is quite funny.  I am on my second e07.  Both cracked.  I am uber careful with pressures and the way I ride.  I accept this tire is the best of a bad bunch, even with the cracks.  Point is:  The tire cracks, not because I rape it.  That makes it a poor product, even though the other tires have their own weaknesses.  The makers should deal with it, not blame the users.  Most of us don't abuse the E07.

Fully agree, and that is also precisely my point.  I am on my 6th e07.  (sucker for punishment  :eek7:) All 5 previously cracked with 2 of them loosing chunks.  The last one is the new compound with less than a 1 000km on.  So far so good.   :patch:   :lol8:
