A pneumatic tire having improved rolling resistance and increased resistance to separation between coat rubber and steel cords embedded therein. The steel cord is formed from two intertwisted steel filaments containing 0.80-0.92 weight percent of carbon. The rubber coat has 100% elastic modulus of 35-55 kg/cm.sup.2. Each of the cords and the rubber coat has a specified mean cross-sectional area (Sa, Sb). The cords are spaced apart from each other by a specified distance across the junction of adjacent belts.
