I don't think Foose makes 4 lug wheels. For the front, I wouldn't run a tire much wider than 245s or 255s or the tire might rub the fenderwells. Most people will say 17s look the best on the foxes, but some 18s look good too. The widest wheel would probably by 8 or 9 inch. For the rear, 275s might fit, but flipping the quad shocks and rolling the fender lips will likely have to be done to fit them. Some have ran 275s without having to do anything while other times work needs to be done to fit them. You should be able to run 255s without any issues, also depends on how close the tailpipes are to the wheels also.
