In response to what size rim Cavebull uses, this is what I found:
My baby just got a new set of shoes for Christmas.
I too like/wanted the true "truck look" of muds on the rear and street tread on front.
The final decisions; BFGoodrich Commercial T/A's LT, All Season on fronts and spare, and Traction on rear. The 215/85/16 are mounted on original 16" rims. They mount out on the narrow rims just like the pictures (see link). They fill and fit in the wheel-well of the 46' perfectly!
I had the rims sandblasted and tube holes welded in.
