Best guess is 8"-9". Haven't had the tires off for a true measurement but I think they were probably an 8" wheel that ended up wider with the beadlocks added on. I would rather sell them as a set unless someone is interested in just the tires. Don't really want the hassle of separating them. How much were you thinking for the wheels? Let me know and if someone posts up for the tires, I'll think about it.
