Pneumatic radial tires.

摘要

A pneumatic radial tire (1) comprises a radial carcass (2) comprised of at least one toroidal carcass Ply (4), a belt (6) composed of at least one belt layer (11) arranged outside the carcass ply in the radial direction and a reinforcing layer (15) composed of at least one reinforcing ply (16) and arranged outside the carcass ply in the radial direction. In this tire, the reinforcing ply is constituted by spirally winding strip band (17) obtained by covering at least one wavy bent reinforcing element (18) with a covering material (19) of a high molecular weight substance having a low modulus of elasticity.
