I know a guy down the street from my buddy who has a set of Rota Grid racing wheels that he needs to get rid of. They are 17x7.5 +35 or 37 I don't know and have some nittos on them. I think they are 215, but they have pretty good tred left. He wants 400 for the whole set. Is this a good deal and will they fit I tried to look up some common sizes but I didn't 17x7.5 +35 as one of them. I would run on the nittos for a season of autocross, but whats the widest I could fit on that size wheel if I wanted to go bigger? I would like to eventually run 255s all around for racing.
