Good evening everybody, I asked about wheels for my Cobra in the tire section a few days ago but got no responses, so I figured I'd post up here. People always seem to respond quickly and I appreciate that.

Anyways, my tires need to go as soon as possible. I'd like to buy some new wheels and tires at the same time. So I was thinking of going with an 18x9 in the front and 18x10 in the rear. What is the maximum tire width I can go with on the 9 and 10 inch rims? Or should I just go for a 10.5 inch rear so I can put a 315 on it? I've heard that you need a new bolt or something to fit a 10.5 inch with the IRS. Any answers would be greatly appreciated!
