Very nice. I've allways liked these. I play with Tireracks wheel configurator all the time. Check bolt pattern/wheel offset combo for the 18's. Limited 18" tire selection in the Prius OEM rolling rate/diameter. 18's are also wide like 10" wide. May rub up front when turning. Try the gen 3 forum for lots of aftermarket wheel and tire threads and the sticky at the top of this one. Just about everything you could think of has been covered before. Should be some nice pics of these rpf1's on a white gen 3 in 1 of the threads somewhere on this site. Gen III aftermarket wheel thread...post your pictures | Page 42 | PriusChat
Thanks for the information. I'll be running a 18x7.5 48 offset 225/40/18. Do you think spacers would be advisable?
