    • 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.
