I know of an X with 33x12.5 swampers, yes they rub, but I don't think they would have fit without a t-bar raise.

T-bars on Xs are all over the map, some are high, some are low. Apparently Nissan doesn't spec them very well before they leave the factory.

Measure the distance from your frame to the ground, on level ground and crank them up a bit, lower the X and measure again. There is no magic formula.
