A belt cover layer is provided on an outer circumferential side of a belt layer. The belt cover layer is constituted by a band-like member in which steel cords are embedded in rubber. Adjacent revolution portions of the band-like member are wound spirally in a tire circumferential direction so as not to contact each other in a region of at least 50% of a belt width centered on a tire equator. A load-strain curve of the steel cords has an inflection point in a strain region of 1% to 3.5%. An average elastic modulus when the steel cords are subjected to a load from 50 N to 100 N is from 25 GPa to 100 GPa.
