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?

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:

Slightly off topic . What is the average price for the 90/90/21 Mita E07 ? I phoned last week here in nelspruit . Bikezone didn't have but will get for me @ R 755 Fitted , then Rudemans said they have got @ R700 fitted . When i went there today no one knows who quoted me that because it is R1100 fitted , well i told them in not so many word where they can go put their tyre !!
When i am good , i am good but when i am bad i am even better

Just for interest I watched the fitter here in Centurion fit my new E09 tyre yesterday. He tore my bead  badly but no problem just coated it with more soapy stuff
and fitted the tyre just like that. I went to the manager and he had him take it off again. Promised me a new tyre (which apparently will be here today ),fitted my old tyre again and now I am nervously waiting,hoping,wondering if my nat. bash trip is now sunk.
So check while they are fitting your tyres so no damage is done at the fitting machine already.

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.

whilst its far from ideal as you can get water in the bead which will rust in the long term and weaken the bead wires. BUT unless the bead wires were broken you will be ok...rust to that extent doesn't happen over night!

No I don't want to be just "ok". I have done the sikaflex conversion with my rims which works fantastic for me with 1x E07 and 3x E09 tyres so far. With this damage it just wont work anymore. When I buy new I would like to get new fitted and not new with damage that "should be okay". Also I am a solo rider with most of my trips in very remote areas where I must have trust in my tyres and the way they were fitted.

The Adventure returned yesterday and I checked the rear tyre pressure as is.
TPM reads 230
VDO handheld reads 245.

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

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. I will follow up with the factory for a definitive answer ASAP!

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:

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!

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
