Pneumatic tire

A pneumatic tire comprising at least one carcass extending toroidally between a pair of bead portions as a skeleton, and at least two belt layers each formed by rubberizing a plurality of steel cords arranged obliquely with respect to the tire circumferential direction on the outside in the tire radial direction of the crown portion of the carcass, wherein

• the steel cord consists of two core wires and six sheath wires twisted together around the core wires;
• the interval between adjacent steel cords in each belt layer is not less than 1.09 mm and not more than 1.39 mm;
• and the gauge of the belt layer is not less than 1.22 mm and not more than 1.60 mm,
• in the steel cord, the core wires are arranged in parallel without being twisted together,
• in the steel cord, the wire diameter dc of the core wire differs from the wire diameter ds of the sheath wire, and
• the ratio of the wire diameter ds of the sheath wire to the wire diameter dc of the core wire satisfies ds/dc>1.2.
