Abstract: PROBLEM TO BE SOLVED: To provide a single-layer twisted steel cord for reinforcing rubber products having sufficient rubber penetrability and excellent fatigue resistance and to provide an automotive tire using the steel cord in a reinforcing material.
SOLUTION: The steel cord is obtained as follows. At least one wire 11 of a steel cord 10 having a 1×n structure is provided with a small spiral or wavy preform. In the wire provided with the spiral or wavy preform, the extent of protrusions from the cord outer periphery is regulated so that there exists no site where the ratio L/d of the deviation range L of the locus from the base line (sine wave) of the spiral preform for cord twisting in the projection plane of the preformed wire 11 after untwisting and loosening to the wire diameter d exceeds 0.7 in the whole round angle of the wire and there exist ≥2 sites where the ratio L/d is within the range of 0.07-0.7 per twisting spiral pitch.
