Abstract: A safety tire and wheel rim assembly incorporating a safety tire support member which is capable of slippage relative to the rim. The wheel rim is of substantially uniform diameter between its bead seats and a pair of spacer members are provided, one on each side of the safety support to give axial location and a bead restraint. Each spacer member has a low friction interface with the support member and a high friction interface with the tire bead.
