I bought a set of michelin-X tires for my wife's 91 Dodge Shadow. She went to discount tire to have them rotated and balanced. The discount employee walked out to have a look. She had mentioned something to him about small dry cracks on the tires and them being only a year old.

He got under the car enough to look in behind them. He said that michelin had had some cracking problems with the X tire. These also had that problem. He gave her 4 news ones for a small adjustment price. She traded the car off about 6 months later for a used Ranger pickup.
