I guess I am one of the lucky ones. I too had BOTH my front tires get "bubbles" along the rim. They were found when I switched from the Continental-Winter to the Michelin-Summer tires. I had the work done at NTB in my area. They happen to be a Authorized Michelin Center & called Michelin for me. Ten minutes later I was told that I was getting 2 NEW tires ... at no charge.

I gotta tell you, NTB has been amazing !!! In an earlier thread (by me), I talked about NTB's willingness to "match" tires prices on Tirerack.com for the Continental Tires, and I was able to get NTB's Road Hazard Warrantee.

Good luck to anyone that has a problem with their Michelins!
