I had the same factory size. Not to many options out there. Hence folks get another, wider wheel or lift and go bigger tires. The man issue is the 7.5" width coupled with the +50mm offset. 255/55/18 is the widest I have seen in person. They looked good. Slightly shorter than stock, barley noticeable. I have seen some 265/60/18's in threads, but way to much sidewall bulge and the bolt had to be trimmed. With a wider wheel and proper offset I think you can run up to a 275 width in front before you hit the sway bar and such. Personally, I would not run any wider than that so it wouldn't "float' down the road when it rains or snows.
