Abstract:
1. A portable universal apparatus for seating a bead of a wide range of sizes of tubeless tires on a wheel rim comprising: a main support frame; a rigid tubular air ring; a compressed air tank for holding a large quantity of compressed air and including an air discharge valve; said support frame including a wheel rim support surface and a wheel rim retainer for securing the rim in a generally horizontal position atop said rim support surface; said air ring including an air inlet port connectable to said air discharge valve and being connectable to and supported by said support frame in a generally horizontal position lower than said wheel rim support surface; said air ring being vertically adjustably positionable on said support frame and including a plurality of air discharge ports spaced around a length of said air ring, each of said discharge ports receiving one of a plurality of air discharge tubes, each said discharge port angularly oriented to position each discharge tube at an acute angle with respect to an upright central axis of the wheel rim; said plurality of air discharge tubes being of differing lengths which cooperate with the vertical adjustability of said air ring to position an open upper distal end of each of said air discharge tubes in close proximity between a lower rim seal and a lower sealing bead of a tire whereby the lower sealing bead of a tire loosely mounted on the rim is forced downwardly into sealing engagement with the lower rim seal when a portion of compressed fluid in said air tank is released into said air ring and discharges from each of said air discharge tubes.
