I've heard of the internal beadlock from a Jeep buddy of mine. He said that you can even drive your truck on it if you tear the tire . Not sure if it's the same system as this one. I think that the one he was looking at is actually like an intertube that you fill with air as well to puch against the inside firewall and lock the bead onto the rim. One nice advantage to the internal beadlock system is that you can drive on the road with a beadlock system and not get harassed by the local law enforcement.
