ABSTRACT:
An apparatus for the mounting/dismounting of tires on wheels. A bead breaker module with elongated pressure clamps pivotally moved by an actuator such that the elongated pressure clamps extend from the perimeter of a tire to a position proximal the tire side and bead; the actuator urges the elongated pressure clamps together to disengage the bead from the rim. A tire mount/dismount module having a base plate affixed to a wheel; a receiver and drive assembly rotatably affixed to the base plate with a receiver receiving a bead rolling tool which is inserted between a tire bead and wheel rim and which, when the receiver and drive assembly is rotated, disengages the bead from the rim or, when installing a tire, engages the bead relative to the rim. A bead rolling or tire iron tool has ellipitical cross-sections proximal its ends and extensions, bearing surfaces at its bottom, a rectangular cross-section intermediate its ends and a slot intermediate its ends.
