It won't fit 245 or 235.. especially without rolling your fenders. You're gonna have to roll. Most people get 225/40. 235 might not fit at all. Safe bet is to sell the tires and go 225/40's. It would only have a small little stretch, if any at all.
I got the 235's instead of the 245's so I'll let y'all know how they fit and post pics. The only reason to roll fenders is if the car is lowered and I don't like the typical lowered ride quality (or lack thereof) or the look of a seriously lowered car. I've seen 225's on an 8.5'' wheel and can't stand that look so I couldn't do it. At most, the car will be lowered about 3/4 of an inch...that's it. I like my sanity and having to think about traversing speed bumps certainly won't help. So when I asked if they'd fit, I was asking with a "close to stock height" in mind. Thanks for the response!!
