PoorBoy well as they say Rubbin is Racin, Not really, couple points that may ease your mind.

The rails on the truck are flat and smooth so if the tires ever do rub, the only thing lost will be the Hoosier white paint, the tires are also canted in due to my wood axle support hitting the sidewall near the floor, I expect from my measurments when the bed is back on and the wheel is mounted we will have the 1.5 to 2" of sidewall clearance.
