I have a 1982 fj40 with stock wheels but 4 inch lift. with 35's i will loose to much power so 33's or great. i have 33 x10.5's right now, can i fit 11/5's on the stock wheels, i have seen 12.5's actually mounted on the same stock wheels but will 11.5's mount easily and stay on the stock wheel or should i get new wheels.
