ABSTRACT:
A safety wheel including a combined flat protector and bead stopper structure radially fitted in the tire around the inner periphery thereof and having a closed frame-like cross-sectional configuration of a substantial modulus of section. The flat protector, being made itself of an elastic material in a substantially H-shaped cross section, is easily deformable and can be readily inserted in the tire and, once combined with the bead stopper, which clamps the opposite side wall portions of the flat protector and the respective bead portions of the tire against the rim flanges, exhibits a substantial rigidity enough to support the vehicle weight, as when the tire is punctured. The rigidity of the flat protector per se is also increased by means of reinforcing cords of unstretchable material embedded therein. Formed on the outer periphery of the opposite side walls of the flat protector are a pair of laterally aligned straight puncture-sensing regions which extend in parallel to a tangent thereto, lying radially outside of the bottom of the annular recess in the outer periphery of the flat protector of H-shaped cross section. The straight puncture-sensing regions, allowing the vehicle body to descend each time such regions are positioned directly opposite to the road surface during travel of the vehicle with the tire punctured, serve to produce a puncture alarm signal in the form of shocks transmitted to the vehicle body, which warns the driver of the need for prompt tire replacement immediately upon tire puncture.
