I'm gonna put Staun internal pneumatic beadlocks in my rims. They lock both the inner and outer bead to the rim, unlike standard weld-on beadlock rings, and they act as run-flat tubes, keeping the rim off the ground and sidewall a little if there's 0 psi. One guy's tire went flat on the way home from a run, he was driving at 50-60 on the highway...steering felt funny but he kept on going till his friend pulled him over. The Staun was ok but the tire was screwed. If you wanna change rims the Staun's come out and make your new rims beadlocks...how cool is that.
