 My car has 30,000 miles and I was just told 2 tires are showing wear, after already replacing all 4 tires 8 months ago!! When I replaced the original tires I went to a reputable tire dealer and replaced them. I spent a lot of money on them and the tires have a great reputation so I was shocked to learn by the MB service department today 2 of them are wearing out! Really?? Maybe it’s not the tires. Maybe something is wrong with the car design??
