Abstract
A wheel assembly (10) having self-contained tire mounting and demounting capabilities includes a closed torus tire (18) mountable on a wheel rim (11). The tire (18) is forced onto the wheel rim (11) by a plurality of retainers (25) which are driven into a plurality of mating slots (13) in the wheel rim by bolts (31). Similarly, the tire is forced off of the rim by screwing the bolts through threaded apertures in the retainers and against the wheel rim. Thus, the tire can be demounted from the wheel rim and that tire or another tire can be mounted on the wheel rim without removing the wheel rim from the vehicle.
