Has anyone had any problems or concerns with their Michelin Primacy tires on the new SHOs? I was looking at mine Saturday and the rear driver side is the worse of the bunch. In between the treads are surface cracks, some more prominent than others. The car rarely sees rain and stays in my garage. I could see if the tires had alot of miles on them but I only have 9,000 on the odo. I need to post pics up on here. My dealer said to just keep an eye on them as it passed inspection yesterday. Pics will be coming when I get some good shots.
