Does wheel width effect what offset you should run? Meaning, if I run a 7.5 with et 48 and want to go to a 8.5 should the offset change as well to keep from rubbing the strut? I have a wagon which already has limitations but want to run a larger wheel (both wider and taller). My plan is to run to a 225/40R18 (or 17) as long as I don't have to have neg camber or fender pull. If anyone running a bugeye wagon has some input it or does/don'ts it would be greatly appreciated.
