As described in another thread, I just went through the bubble problem and wound up having Michelin replace the tire for free.

But it wasn't easy. My Chrysler dealer who has in all other respects truly lived up to a 5 Star rating, pointed out that the tire is not covered under a Chrysler warranty but strictly needs to be dealt with by Michelin.

I wouldn't be surprised if this time around your Chrysler dealer invites you to take the tire problem directly to Michelin yourself this time. The Michelin dealers are told to take the tire off the rim and inspect for interior bruising or other sign of road hazard. If they declare road hazard, anything can happen. Michelin MAY decide to give you something, but you probably won't wind up with a replacement.

Mine was determined to not be road hazard, so I get a new tire.

I'd suggest everyone keep an eye on their tires, this bubbling MAY turn out to be a problem with the S2...
