I am an 09 3.8L owner, with approx 64 K Kms I am on my second set of tires soon third. I changed the OEM tires Dunlop at approx 31 K Kms, Like the previous set the Michelin are wearing in the inside. I have rotated every 5k, Tires installers have balanced and aligned the car and stated that problem is with the car, the dealer stated the problem is with the tires. I am in a catch 22 here. Anyone with the same problem.
