while i haven't put them on yet, i just got my 17x7 40 offset w/ 215/45/17 and love the way the sidewall looks. 215/45 iirc is the closest to stock size overall. IF i did the 225 it would probably be w/ 40 profile. but my streets suck so the 45 makes me feel better. i would not do 225/45. the sidewall will look big. i'd say one or the other. 215/45 or 225/40.
