SOLD. I have a set of 4 - 37" x 12.50" x 15" Good Year MTRs mounted on classic 70's style desert racing slots - rims are 15" x 10" somewhere between 3" and 3.5" backspacing. Think it's 3" - currently mounted on a disc brake 40 and also clears my 4x4 labs arms. Rims need polishing and a few have some rock rash on the outer edge. I have wheeled these once, and currenlty only use them as street tires with maybe up to 1,000 miles on em. Tires look near new, no rock rash and 95% or so tread. NEW PRICE - $1,200 obo. Make a Reasonable offer...now need to unload these for the storage space. Oops - Includes a 5th rim with a 35" BFG MT with 50% tread mounted.
