you are not understanding the concept of width at all. Fittment is about the tire. You just get a rim that works. For instance if you want 255 wide, you should get at least an 8.5 if not a 9.0" wide rim. However, that has nothing to do with the fitting! The offset you need is dictated by the TIRE width, not the RIM width. 255 is 30mm WIDER than 225 so you need about
15 LESS OFFSET for the same fender clearance as 225s
If you want to run 255s on a WRX, I'd advise 33-38mm of offset. You'll be well out of factory spec which will reduce the suspensions performance but they WILL fit. +45 is pushing it. Your tire is way way way wider than stock and your offset hasn't moved enough (course, you prob don't want it to). so I think if you put 255s on those rims, you will get rubbing.
