Pneumatic Tire Bead Breaker NSN 4910-01-325-2974

Item Description

A hand-operated leverage device designed to loosen tire beads from a wheel rim for tire removal. It consists of a base-mounted upright which serves as a fulcrum for an attached lever arm from which a leg with a shoe is suspended. When the wheel and tire assembly is positioned flat on the base with the shoe against the upper side of the tire at the rim, downward pressure on the lever arm forces the tire bead to break away from the wheel rim. See also demounter, pneumatic tire.
