I had my right rear tire give out on me over the weekend. Looks to me like some belts blew apart inside. The tire went flat, and both inside and outside sidewalls are deformed. So, after a tow to Kerbeck in A.C. and a $450 bill :bang: , the tire was replaced. The original tires have 10,000 miles on them. Should I have any concerns over running rears with different tread depths? Will it upset the balance of the car? The dealer says no (but who trusts them?).
