I had 30's on mine unlifted with jeep CJ wheels, they were small 30's and they were worn, measured in at 28". They were close the hitting tha back of the fender, innder fender
My new/used BFG tires, are 235/75/15(28")on Samurai wheels, and they only rub on the frame, but were VERY close(when turning) to the bottom of the inner fender at the back of the front tire. even with a lift, they still rub the frame, but they were further away from that inner fender piece. A hammer would make more room.
