摘要： A device for mounting and demounting tubeless tires with respect to wheel assemblies includes a wheel support structure upon which a tubeless tire and wheel assembly is positioned. An elongate vertically disposed mounting member is releasably locked to the wheel support structure and projects vertically upwardly therefrom through the tire and wheel assembly. A wheel clamping member projects through openings in the mounting member and is urged into clamping relation with the wheel by an adjustable threaded clamping bolt. An elongate lever has a tire removing member at one end thereof, which is insertable between the tire bead and the wheel rim so that, when the lever is maintained in engaging relation with the mounting member and is moved through an arc of 360 degrees, each tire bead will be successively removed from the wheel. A tire mounting shoe is mounted on the other end of the lever and is operable to stretch and force the tire bead upon the wheel rim when the lever is moved through an arc of 360 degrees and is maintained in engaging relation with the mounting member.
