    Abstract: Provided by the present invention is a technique which can, in a pneumatic radial tire using corrugated steel cords in the circumferential bent, improve the durability of the corrugated steel cords in order to prevent fatigue rupture thereof caused by an increase in energy input.The present invention is a pneumatic radial tire which has a carcass 1 as the skeleton extending in a toroidal shape between a pair of bead portions on either side of the tire, as well as a belt layer 2 and a tread layer 5 successively arranged thereonto at the outer part in the tire radial direction. The belt layer 2 comprises at least one layer of circumferential belt 3 which comprises a plurality of corrugated or zigzag-shaped steel cords extending along the tire circumferential direction, and when the steel cords are removed from the circumferential belt 3, the bending radius of curvature (R) of the steel cords is within the range from not less than 18 mm to not more than 125 mm.

    Abstract: There is provided a steel cord for reinforcing rubber article having superior durability, and a pneumatic radial tire improved in steering stability and durability by using it. There is also provided a pneumatic radial tire satisfactorily combining steering stability, durability, and good cost performance required for a high performance radial tire intended for the application to a high performance passenger car. The steel cord for reinforcing rubber article has a 1×n structure composed of a plurality of steel filaments stranded in the same direction at the same stranding pitch, wherein the number of the steel filaments is 6 to 12 and the diameter of the steel filaments is 0.08 to 0.21 mm. In the pneumatic radial tire having a carcass (1), as a framework, extending toroidally between a pair of bead parts (11), with a crown part of the carcass being reinforced with a belt layer (2), the above-described steel cord for reinforcing rubber article is applied to a cord constituting the belt layer.
