Abstract: To provide a pneumatic tire wherein the lightweight properties of a tire is secured while improving the plunger energy and BES resistance thereof, which is particularly suitable for tires for a large passenger car or extra load tires.A pneumatic tire comprising a carcass 1 as a skeleton, and at least two belt layers 2a, 2b 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 is provided. The steel cord is composed of two or more core wires and five to seven sheath wires twisted together around the core wires; the interval between adjacent steel cords in the belt layer is more than 1.0 mm and not more than 1.50 mm; and the gauge of the belt layer is not less than 1.20 mm and not more than 1.60 mm.
