Abstract: A steel cord (4) for reinforcing rubber articles and a pneumatic radial tire (10) having a belt layer (14) using the same, in which the steel cord comprises a crimped-curled core (2) made of a steel filament wave-shaped in a plane (crimped) and turned (curled) and 5 - 8 sheath filaments (3) wound around the core in the same direction as the turn direction of the core. The wavelength λc of core-crimp is preferably defined as 8dc≦ λc ≦ 30dc when the diameter of the core filament is dc, and the turn-number nc of the core around the center axis of the core per one wave-length of the core-crimp is preferably defined as 0.12 ≦nc≦ 0.85 (turn/pitch).
Since the core filament is three-dimensional, the core periphery in cross-section is lengthened and the rubber penetration property is remarkably enhanced so that the resistance to cut separation indicating tire durability is enhanced. The space between cords can be lengthened when the strength is constant and the resistance to BES is enhanced. Productivity is better than that of core crimped cord.
