    Abstract: PROBLEM TO BE SOLVED: To provide a steel cord for reinforcing rubber article excellent in durability compared to conventional one by improving structure of the cord, and to provide a pneumatic radial tire improving steering stability and durability by using the steel cord.
    SOLUTION: The steel cord for reinforcing rubber article has 1×n structure composed of a plurality of steel wires twisted in the same direction with the same twisting pitch. Wherein the number of steel wires is 6-12, and the diameter of the steel wire is 0.08-0.21 mm. The invention relates to the pneumatic radial tire comprising a carcass 1 toroidally extending between a pair of bead sections 11 as a skeleton, and reinforcing crown section of the carcass with a belt layer 2. The steel cord for reinforcing rubber article is applied to the cord constituting the belt layer.
