Yup, it's true. Just purchased and installed some 255/85/16 Bfg Mud Terrain KM2s. They actually measure 33.8x10.50. I previously had the torsion key turned a couple of times. I think it was equivalent to about 1.25 when I measured from the ground to the bumper. But it does not rub and it's not even close. Even when it's flexed.
