Tire with high strength corrugated sidewalls
First Claim
1. A combination, comprising:
- a rim having first and opposite sides and a peripheral lip extending around each of the first and opposite sides of said rim, each peripheral lip having an inside wall, an outside wall, a bottom coextensively connected to said rim, and a top lying opposite and spaced from said bottom by said inside and said outside walls; and
a tire mounted on said rim, said tire having a crown extending circumferentially therearound, a pair of sidewalls located below the crown and lying opposite one another to surround said rim and lay against the peripheral lips at the first and opposite sides of said rim, and a series of corrugations formed in at least one of said pair of sidewalls, said series of corrugations having first and opposite ends and alternating inwardly extending depressions and outwardly extending projections that are aligned side-by-side one another and that run radially along the at least one of said pair of sidewalls such that the first end of said series of corrugations is located so as to be trussed across the top of one peripheral lip at one of the sides of the rim in order to provide side load stability to the tire at said rim when the tire is subjected to side loads during cornering.

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