Tire with high strength corrugated sidewalls

A method for making a tire comprising the steps of:

• molding a pair of sidewalls that lie opposite one another by bonding a plurality of fibrous plies together one on top of the other;
• molding a crown extending circumferentially around said tire and located radially outward from said pair of sidewalls;
• forming a reinforced bead in each of said pair of sidewalls such that said beads extend around said sidewalls opposite said crown;
• and
• shaping the plurality of fibrous plies of each of said pair of sidewalls so that each sidewall has a series of corrugations extending continuously therearound, and each series of corrugations has alternating inwardly extending depressions and outwardly extending projections that extend side-by-side one another between the crown of said tire and the bead of a respective one of said pair of sidewalls.

A tire, comprising:

• a circumferentially extending crown;
• a pair of sidewalls spaced from and lying opposite one another and coextensively connected to the crown;
• a bead located within each of said pair of sidewalls such that said beads extend around said pair of sidewalls and lie opposite said crown;
• and
• pluralities of corrugations being formed in at least one of said pair of sidewalls and lying adjacent and side-by-side one another, each one of said pluralities of corrugations having first and opposite ends and alternating inwardly extending depressions and outwardly extending projections that run radially along the at least one of said pair of sidewalls,
• wherein the bead that is located within and extends around the at least one of said pair of sidewalls lies inwardly of each of the inwardly extending depressions and each of the outwardly extending projections of each one of said pluralities of corrugations and wherein the first end of each one of said pluralities of corrugations encompasses at least some of said bead.
