I'm running 20's, 7.5 inches wide, +40 offset. 225/35/20 tires right now, but have room for 245/35 and will be changing them out. I think this is how the OP is wanting them to sit, huh?
Edit: photo uploadsfrom the PC not working now? I'll photobucket or something...
Yeah thats exactly how I want it to look! Thats what I was meaning when I said flush. And yeah carid.com is a solid website for rims, all kinds to pick from and they custom make them to fit your car, so you can get any bolt pattern or offset needed.
