Blew out a sidewall on the right rear a while back on my clk430. It was a michelin mmx pilot sport. I fortuneately had an extra set of wheels and tires. Not I would like to put a tire back on that rim. The other three tires have less than 10K on them and I would be looking for one with about the same or less mileage. Thanks Steven<br> BTW, the new clk, although improved in many areas, is not as pleasing to the eye. It is too cookie cutter in design with the other benzs, no individuality, no where near as aggressive looking as the present design, imho.
