Just back from a 300 km / 140 mile cruse and low and behold I can see the belts on the right rear. 16,000 km/10,000 miles on contis. I am not to hard on any thing I drive but this is scary, I have been watching the tread and checking pressures on a daily so this came as a surprise. My baby came in from the states, and I think somewhere along the line that tires and rims where swopped, will be at the dealer manjanna!. So its new shoes all around, no question about that. Question is do I need a 4 wheel alignment ?
