Your wheel bolt pattern is 5x5 and you have 16 inch rims (as designated by the r16 on the tire size). You will need that rim size in a 7 or 8 inch wide rim. You won't be able to fit much larger tires, so I would stick to that size. Also pay attention to the backspacing. Your stock wheels have 5-5.5 inches of bs. A lot of aftermarket jeep wheels have much less bs to fit wider tires , and this will space your tires out. If your going for that look then great, just something you should know.
