ABSTRACT:
Disclosed is a run flat tire for motorcycles having a high handling stability, cornering stability and durability even when the tire is punctured during running and the pneumatic pressure inside of the tire becomes equal to atmospheric pressure. The run flat tire has a pair of sidewall-reinforcing layers each comprising (1) an elastic filler extending from an end location adjacent a bead core in a bead portion to the other end location in a tread portion through a sidewall portion of the tire and (2) at least one reinforcing ply which extends along one side surface of the elastic filler toward the tread portion, is turned up around the end of the elastic filler in the tread portion and which then further extends along the other side surface of the elastic filler toward the bead portion.
