Pilot SX MXX3. That would be the OE rear tire for CLK 430 up until about the middle of 2000. I had one totally come apart on the freeway (but I'm sure there's no flaws, right Michelin?). The car's only got 7k on it and I need to match the others. Perhaps someone has a take off or some single one off a wreck, etc...Thanks for your help.
