One of my wheels leaks down to almost nothing after a few days (doesnt even register on the guage) and the tire does not look flat but just really low. I have the factory bead locks in all 4 wheels. I just bought 4 new O-rings and plan on replacing them all when I get new tires. One of my wheels hasnt leaked a LB since I put them on, the other 2 have very slow leaks, like 10lbs a week. It is a major hassle having to air up before each trip but gives me time to inspect the rest of the truck. I dont think I would try running them without a bead lock since they dont have the lip built into the rim to hold the bead on. I paid $250 each but that included tires, one was brand spankin new, the others ranged from 50-75% tread.
