I love my Arc-8's. 235/40 front and 265/35 rear Hankooks for me. No rubbing anywhere at all.
Glad I was talked out of trying 245 in the front, with the factory alignment they would not have fit. 235 just barely makes it. The rears on the other hand - the offset seems perfect as my 265's have plenty of room on each side. Don't buy tires on my recommendation but I think 275, possibly 285 would fit if someone was so inclined.
I've gotten a few compliments on the wheels as well - "great looking car, love those wheels" kind of thing, without me even mentioning them.
