Ok 30k miles on the michelins and they are worthless. Noise, incredible, the tractor running down the road was quieter. Just put Cooper tires on, CS4 touring, what a difference, now for the interesting part, the camber on the car is out and they could not adjust this. they could adjust the toe in but not the camber, said it probably happened when they shipped the car and when they tied it down so tight then suddenly release all the tension it will spring the car.. what do you think? Either way taking it back to the dealer for a look. But this is my third set of Cooper tires and really like the them, they are quiet on the Ford 500 that I drive to work, got 70k on the first set.
