Abstract

An entirely mechanical lightweight economical tire bead breaker is disclosed which can be conveniently operated with a single hand wrench. A wide variety of tire sizes can be serviced by the tool. A clamping screw and cooperating clamp bar unit forces three wedges between the tire bead and rim. The center wedge is then driven away from the rim flange to dislodge the tire bead through operation of a breaker screw.
