I've got a set of 5 Interco 31x10.50 TruXus M/Ts on black 15x8 AR-767 steel wheels. I these tires for ~2 years on my '98 XJ before I upgraded to a larger tire. The vehicle is a trail only rig, so the milage on the tires is low... maybe ~7k?
Tread is in good shape... A few nicks in the sidewalls, some rock rash on the wheels. Tires all hold air, one might need to be rebalanced. I'll sell the set of 5 w/ wheels for $350 + shipping. I'm located in southern NH. If you want 'em send your shipping zip code and I'll figure out how much it will cost.
