Abstract: A steel cord for reinforcement of a radial tire and a radial tire employing the same are disclosed. The steel cord is made of more than three steel filaments of which one or two filaments are regularly twisted, the other filaments are open-twisted and each filament is twisted in same direction. Each steel filament using carbon steel has the carbon content of 0.7 to 0.96 wt %, the tensile strength of the filament is in the range of 260 to 380 kgf/mm2, the twisting pitch is 10 to 20 mm, and each filament is plated with brass. The topping characteristic is improved and the uniformity of tire is enhanced.
