Abstract: An improved tire changing apparatus for changing so-called "difficult tires" and/or changing tires at a more rapid rate and/or use in facilities having low pressure or widely fluctuating air pressure sources. The apparatus includes a base having an upwardly extending frame mounted thereon, a tire receiving table mounted on the frame, an elongated rocker arm pivoted at a point intermediate its ends to the frame, upper and lower bead loosening assemblies associated with respective ends of the arm, a rotatable post mounted on the table top, a linkage interconnecting the arm and the post for rotating the post in response to pivotal movement of the arm, a first cylinder connected between the arm and the base for pivoting the arm in one direction and a booster cylinder connected between the arm and the base for pivoting the arm in the one direction in concert with the first cylinder. Also disclosed is a retraction mechanism for an air chuck.

Abstract: Tire bead seating and inflating apparatus of the type employing an arcuate tube having its interior connected to a source of air and including inwardly directed nozzles for directing a high volume of air under pressure toward the interface between a tire rim and a tire sidewall while air is simultaneously being applied to the interior of the tire through a conventional valve stem. The invention specifically contemplates a kit whereby such an apparatus, along with desired peripheral equipment, may be easily affixed to existing tire changing stands.
