<p>A pneumatic radial tire comprises a carcass (17) extending between a pair of bead portions (13) and comprising at least one rubberized ply (18) containing cords, a belt (21) comprising at least two belt layers (22, 23) containing cords, a belt reinforcing member (30) comprising a belt reinforcing layer(s) (31), and a tread rubber (27) arranged outside of the belt. A pneumatic radial tire comprises: (1) a carcass toroidally extending between a pair of bead portions and comprised of at least one rubberized ply containing cords arranged in a radial direction; (2) a belt arranged outside of the carcass in the radial direction and comprised of at least two belt layers containing cords, the cords of which layers being crossed with each other with respect to an equatorial plane of the tire; (3) a belt reinforcing member arranged adjacent to the belt and comprised of a belt reinforcing layer(s) containing a reinforcing element and extending in a circumferential direction while bending in wave or zigzag form; and (4) a tread rubber arranged outside of the belt in the radial direction, in which a belt protection member containing reinforcing elements embedded at an inclination angle with respect to the equatorial plane larger than the inclination angle of the cord in the belt layer is disposed in the vicinity of the belt, and a widthwise outer end (23a, 30a, 35a) of the belt protection member is located outward from a widthwise outer end of the belt reinforcing member in a widthwise direction of the tire.</p> |
