Inner Air Lock beadlocks work with any traditional wheel or ring-style beadlock and feature a heavy duty internal case that houses an inner tube which, when inflated, presses against the inner and outer tire beads to prevent them from slipping or coming loose. Not only do Inner Air Locks allow you to run very low tire pressures by acting as a true double-beadlock, they also help prevent the wheel lip from getting pinched or damaged by acting as a tire within a tire.
