I would contact Michelin UK asap.

If they are close to you, take the tire in to them.

Looks like the new version PP - dual-sport/SM On-Demand knobby.

I had that happen once with a Continental Contisport. It didn't happen until late in its life however and the goiters where smaller, but lots of them all the way around. When I mounted a new tire it was apparent that the Continental was thoroughly weather checked inside and that the cracks (either from old age or poor care/being left in the sun pre-sale) had let the air into the outer carcass. Very weird I must admit. Good thing you stayed upright.

Just put a little weight on the opposite side. You'll be fine.

One of the BMW dealers metioned that he has seen a couple of road tyres delaminating as shown in your picture. According to him, most of the time the tyre pressure is too low for highway riding, causing overheating of the carcass resulting in delamination.

What tyre presssure were you running?

I was running 36 PSI as per the book

What speeds did you attain prior to failure. Were you working the twisties hard on the run preceding the failure.

WOW! That is nuts!

supersubby · 10-17-2007, 11:46 AM

I was doing the boring stuff coming home from London on a motorway, steady 90 mph and then I noticed the weird behaviour from the back tyre

WoW! I guess that BMW under reported the *actual* rear wheel horsepower...

Next try Hoosiers®, if ya want them race taars....

Gotta get me one! ( still ugly though... )

Super, I would definately recommend that you call the local Michelin guys to have a look at it. Then the arguement of low pressure is flawed...

Hope you come right!

I was a tire buster at times in the late 70's, had to adjust a number of Firestone 500 radials that bubbled up. We just wrote 'tread separation' on the ticket.

My local BMW dealer charged me for a replacement tyre and said they would send the 'Failed' tyre to Michelin for examination.
If Michelin!!!!!!!!!! think the tyre is faulty the BMW dealer will refund my money.
I am a bit put out to say the least, as far as I see it Michelin have 2 recalls running at the moment, one for a front tyre one for a rear.
Both recalls are due to de-lamination of the tyre (what I think has happened to mine)
I think BMW should have replaced my trye free of charge and then took the case up with Michelin on their behalf.

I will have to wait and see what happens

I have to side with the dealer, BMW or the Dealer have no fault in this situation it is Michelin's problem. If they replaced it for free and Michelin did not stand behind it they are stuck, not really fair IMHO.

SergioK · 10-18-2007, 11:54 AM

I don't see how Michelin could ever say that it was not defective, especially after only 800 miles of use. They may try and say you ran too low/high a pressure but regardless, I've never seen a tire do that from wrong pressures. Tires typically only show that kind of failure when something went awry during manufacturing.

Skoeter · 10-18-2007, 01:28 PM

Hope they sort it out and you don't get the short end of the stick...

Good luck!

It depends on where you live I guess. I don't know how it is in the UK or the US, but here as a consumer you only have to deal with the party that sold you the product. The seller has to give warranty to the buyer; if the seller wants warranty from the manufacturer, that is the sellers problem, not the buyer. In a case where there is a clearly defective product like this, the shop would have to give you a replacement tire and afterwards, the shop can claim warranty at Michelin to get refunded for the replacement.

So yes, it is Michelins problem. But that is not necessarily the consumers problem.

Perhaps if signit98 had these front & rear those rims would still be intact after the pothole

signit98 · 10-18-2007, 11:22 PM

...now there's a marketing idea... airbags for tires!

supersubby · 10-19-2007, 10:34 AM

My expectations are the same as Throttlemeister's, I bought the bike 3 weeks ago from BMW and they are responsible for any failure on that bike.
Other wise where does the argument end, my bike has the Ohlins package, if one of those shocks were to fail would you seriously expect to pay for a replacement while Ohlins investigated the problem!
BMW should replace the tyre and then take the battle to Michelin, after all they can decide which tyre they fit as original equipment, thats a lot more pressure to bring to bear on Michelin than anything I could do.
I hope that within a week I will have the answer I want and have my money refunded but I don't feel very confident anyone is going to fight on my behalf.
If I have no success I will speak to Michelin direct and let everyone know how feel (motorcycling press and newsgoups)
With my little problem aside there could be a problem with a batch of these tyre's and if there is even the slightest chance I feel riders deserve to know.
I was lucky and quickly brought the bike under control as I was on a straight motorway/highway, if I had been on my favorite set of twistys this could be a very different matter!
