All terrains on Night Edition 20" wheels?

[SandDiesel]

Has anyone mounted A/T's on the 20" Night Edition wheels yet? I plan to go with 18" wheels and tires but curious about fitment and backspacing if you go with 11.5" wide tire. Brake rotors are pretty large on these, not sure if all 18's fit easily.

Found a truck for sale with A/Ts on the OE black wheels...
