They have the ProComp 6066 in a 20 inch wheel for $1,050 and Toyo A/T's in 305/55/20 for $1,030. (this is for 4 of each) I have not called them yet, but here is a link of what this looks like. I think it is a SWEET setup. It is fairly well set up for off-road, but it does not look really clunky and aggressive.
