ok, so i found a set of wheels i REALLY REALLY like, but they only come in 18 x 8.5 (and 9.5). the biggest offset they have is a 45. will this work? i'd like to run a 225/40R18 so that the bigger wheels have some purpose and aren't JUST for show, but i guess if i had to i could run a 215/40R18. i'm concerned with rubbing the fenders. for now i ride stock suspension, but i'd like to be ok if i decided to lower it someday.... thanks for the help!
