90 % Highway miles ..very littel tire wear
The tires are nearly new except for the cupping on the inside. 90% of miles are highway and I rarely drive hard. The dealer says it is happening becuase of the camber in the rear suspension,
I have put nearly 24K miles on since May. Religously rotating every 7K. After this last rotation I noticed loud tire noise from the front tires. Dealer says it is cupping from the stock suspesion set up on the rear of the car! They say I have to live with it and that they have had similar issues...
