I have 2 35x12.5x15 Big O mud terrains and 1 33x12.5x15 Pathfinder A/T if anyone needs a spare. The 35's have some miles on them. The 33 is in very good conditionm but it does have a plug.I am going to put them in the for sale forum if no one needs them around here. I don't know what they are worth. How about 20 dollars each.
