225/50-16s on the EvoI rims would rub like crazy. you're looking at around 1" increase in overall diameter from stock. as it is you will get a little bit of rubbing at the front of the front fender wheel opening. about where the flare meets the bumper.
225/45-16 is the optimum size for the rims you are using. I ought to know, they're the same rims i have on my 2.3-16
