Abstract: A run-flat tire, i.e., a tire capable of running for a while even when it is flat or uninflated due to a puncture, includes a carcass ply or layer having a turned-up end which reaches one end of a belt layer underlying the tire tread. A crescent-shaped side-reinforcing rubber pad includes a outer-surface-side rubber pad and an inner-surface-side rubber pad arranged which sandwich a fibrous layer therebetween. The inner-surface-side pad, i.e., the one situated inward of the outer-surface-side pad, is thicker than the outer-surface-side pad. The upper end (the end close to the tread) and the lower end (the end close to a bead portion) of the fibrous layer extend slightly beyond the upper and lower ends of the side-reinforcing rubber pad, respectively.
