Abstract
A two-ply radial runflat tire having a belt structure, a ply structure, two inextensible beads and two wedge-insert reinforced sidewalls. The outer ply is reinforced by high-modulus, light-weight aramid. The aramid reinforcement material of the outer ply is clamped around the beads. The outer ply is prestressed in tension during manufacture of the tire. The resultant tire is light in weight and resists upward buckling of the tread during runflat operation.
