Maxum,
The rear tires in my photos are 315/45 ZR17. They don't make those anymore so I went to the Michelin Pilot 335/35 17. They look good and were no problem on the same wheels. I think my wheels are 11" rear and 10" fronts. If I get a chance I will post some pics of the new tires. I bought my car with the wheels so I have no idea of the cost. I can tell you the tires are expensive when you go to the 335's. Not many choices either. There are alot more choices in the 315, but I need lots of traction for my engine.
