Maybe I am just a bit old school but IMO without a 6" lift and 37" tires the 20" wheels look like they should be on some low-rider and not a 4x4 truck. I guess I'm just getting old because it seems like everyone and their brother is running 20's. Hope everything works out with your new wheels, tires, and leveling kit. I know the tires I have are big for 285/70 or at least that is what I have read in comparison to other brands of A/T tires in that size.
