Having a problem with premature and uneven treadwear on the tires and a grinding noise when dropping to low speeds even before the brake is applied. The camber and suspension has been checked and tested and they claim it all checks out okay but we feel we are not getting a straight answer from the dealership service department. We just put a new set of tires on and they are already showing strange/premature treadwear. These new tires have a little over 7k miles on them. At highway speeds, there is a noticeable thumping noise. The car is not driven hard either.

Anyone else having problems with this?
