Since there is a very limited selection of tires in the stock size, I have pretty much decided to go with a 45 aspect ratio tire for a replacement. The best choice to get closest to stock diameter is 245/45-17 for the front and 255/45-17 for the rear.

The stock rims are in the recommended range for Kumho Ecsta MX tires that I will be getting, but just barely. Has anyone tried these sizes? I can't decide if i would be better off getting one size smaller and dealing with the slightly smaller overall diameter.

Thanks!
