A tire (1) having a pair of high strength sidewalls (7) lying opposite one another, wherein each sidewall has a plurality of plies (14) that are shaped during manufacture to have a series of pleats or corrugations (9) formed therein and stretching from the tire beads (24) radially- outward along the sidewalls (7). Each of the series of sidewall corrugations (9) includes a pattern of alternating inwardly extending depressions (10) and outwardly extending projections (12) that extend continuously around the tire (1). The corrugations (9) provide the sidewalls (7) with an integral structural reinforcement, whereby the tire (1) is advantageously capable of providing run flat support and avoiding damage to the rim (20) on which the tire is mounted. According to a preferred embodiment, the tire (1) herein disclosed is ideally suited for use on a motorcycle rim.
