A steel cord/rubber composite reinforcement is disclosed for use in a pneumatic radial tire, the reinforcement comprising a plurality of steel filaments arranged in spaced-apart or isolated relation and embedded in a rubber coat layer. A steel cord made up of filaments is flattened out in the form of a generally crosssectionally oblong, elongated strip having a specified diameter parameter such that the filaments in the resulting reinforcement are held out of contact with each other and the overall diameter of the cord is uniform throughout the length thereof.
