Hi,

I am pretty new to the this forum, I have recently acquired a 1971 GMC C10 Short Bed and i am in the process of fixing it up to my liking. I have lowered the truck with CPP's spring and shock 3/5 lowering kit. I have set of 20" Rev Classic Rallys that I would like to install but I am not sure of what tire to go with. Any help you guys guys could yield is highly appreciated.

1971 GMC C10 SWB
3/5 CPP Drop

Wheel Specs:
Rev Classics
Front - 20" x 8" (4.5" Backspace)
