Has anyone else experienced problems with the front tires cupping? I have 7,000 miles on the Z and I know it is time to rotate the tires, but the fronts are cupped extremely bad. I don't corner the car that hard, just get on it in the straights. They are the stock 245/50 series Goodyears GS-C's. If anyone has experienced this problem have you had any luck getting warranty replacements from Goodyear???

 

By cupping do you mean the insides wear less then the middle?

If the middle wears more they are over inflated. If the sides wear more its under inflated. If only one side of the tire(s) wears more then your alignment probably needs to be fixed.
