I have a ProComp Xterrain M/T 35x12.5x15 that's never touched pavement. Still has the nipples on it, though it is a little dirty from riding on the back of my heep. These tires were $260 a piece new but have since been discontinued. If you need this to complete a set or need a brand new spare, just let me know. I'll part with it for $150 firm. No wheel included, tire only.
I'm in Henry County, about 30 mins south of Atlanta. I'll meet you anywhere from Butts County up to Atlanta, or even over to Newnan.
