An improved clamping mechanism to secure a tire between a bead ring and a wheel utilizing a bolt. The bolt has a ball seat that pivots within an enlarged pilot hole in the bead ring as the bolt threads engage in threaded section of the wheel, pulling the bead ring toward the wheel, eventually leveraging off a fulcrum on either the bead ring or wheel against the tire bead bundle and pressing down the tire bead to lock it in place against the wheel. As the bead ring can pivot within the enlarged pilot hole around the bolt, the bolt is not stressed. Further, the wheel comprising a safety bead and non-skid coating on the inner wall of the wheel to prevent the wheel sliding around the wheel.

A wheel includes an inner wheel half defining a plurality of inner bolt apertures and having a mating surface. The wheel also includes an outer wheel half defining a plurality of outer bolt apertures and having an inner surface. The plurality of outer bolt apertures are configured to be aligned with the plurality of inner bolt apertures such that each of a plurality of bolts may be received by one of the plurality of outer bolt apertures and one of the plurality of inner bolt apertures, forming a seal between the mating surface and the inner surface in response to each of the plurality of bolts being tightened. In response to a predetermined number of bolts becoming loose, a first portion of the mating surface may separate from a second portion of the inner surface, breaking the seal.
