I was thinking about picking up a set of 15" Rotas... what's an ideal tire size on Civic's with stock suspension? I have a friend with a set of 205/60/15 hes willing to give me, they might have to work until I can get get cash for something different (or until they wear out!) Anyway, what's good? I need enough tire to keep the ride smooth... 205/50? or 205/45?
