Abstract
A safety tire and wheel assembly for pneumatic tires which includes a safety insert having an inner portion extending around the wheel rim base for clamping the tire bead toes against the opposing rim flanges and an outer portion projecting radially into the tire cavity. A band of resilient material such as rubber is carried by a circumferential array of bearing elements in a depression formed on the outer surface of the core outer portion for supporting the tire tread with respect to the wheel rim upon loss of tire inflation pressure. The wheel includes a two-piece rim comprising a first rim portion welded to a wheel disc and a demountable rim portion mounted by the circumferential array of clamps to the fixed rim portion. A sealing ring is disposed between the rim portions for sealing the tire cavity for tubeless operation.
