If 225/60 works, you can use the Firestone SZ50EP in that size- decent tire. If you go 225/55, you can use the Michelin Pilot HX MXM, good quiet tire, but not totally performance-oriented. If you go 225/50, there are lots of choices. What's wrong w/ the AVS intermediate, anyway? I like those tires, just don't last very long. Taka
