Abstract
Pneumatic radial tires for automotive use are constructed with a belt layer reinforced with a steel cord of a unique structure. The steel cord results from the preformation of a single steel wire into a spiral shape meeting specified spiral parameters as determined by specified spiral diameters, specified wire diameters and specified spiral pitches. Significant weight saving is attainable with sufficient driving performance.
