MITAS E07 Tread failure

[Vis Arend]

Without hi-jacking your thread, you are lucky to receive such special treatment.      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.

After one PM, two mails and 4 telephone calls you and Danny have my details.

The E07 on my 990 always has chunks out of it (on about my 3rd or 4th rear), but that is with great abuse that includes wheelies, Schurweberg, Wildwest enduro etc. Will I fit it again, for sure 

[Stofdonkie]

Too many examples hereof on the interwebs to make it an isolated and/or usage issue IMO.

Maybe the 'carbonfibre nanotechnology' (  ) needs to be topped-up.

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.

Chunks might be a strong word, here some pics. Prob about 3500km on this tyre

[JustBendIt]

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

Apologies for this belated reply. Been working a bit

The tyre was still inflated as the guy 'hinkepink' back to the Petroport to wait for me with the replacement tyre.

Pressure was unfortunately not checked. Should've

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!!!

This was my same question on a previous thread, no answer. I think there is a max load shown on the tyre if I am not mistaken.

You are 100% right...... I have just checked on my tyre..

328 kg @ 2.8 bar

[THROTTLE JOCKEY]

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.

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.

[The Badger]

Very interesting thread....

I often ride at about 560 to 580 kg gvm and speed between 140 and 160. No hassles yet. ... touch wood.

[KTMjedi]

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!

[ExploreSA]

Which is practically impossible under normal riding conditions.

Meaning overload discussions is a waste of energy.
