Bomar
SILVER Star
That is great news for you then b/c that tire is very square and says 13.1 w.
Another tire to look at would be the BFG KM2 35x12.5x17.
They run skinny and shows only 12.5 wide so you gained .6 inches and that is a ton in a front of a truck. That gives you a 15 mm advantage in backspacing for the wheel on the KM2.
Depending on the offset between your Tundra wheel and the Rock Warrior wheel the KM2 might work on 18s and no need for new wheels.
