Here are a few pictures I took from the stretch on both size wheels. The strech isn't that bad if at all. If you want bubbly tire, perfectly ''square/flush with the wheel look'' or if you want to protect the lip from hitting a curb ''if you ever do so'' get a larger tire. Both 225/40 and 255/35 are more ''rounded towards the inside'' then stretched.
I'm really happy with the outcome, now only waiting to get the car out of storage! I think fitment will be perfect, even with stock suspension, will update when I get a chance
Thanks, hope it helps! if you have any question, feel free to ask!
