Zusammenfassung:Provided is a pneumatic tire that includes a belt reinforcing layer formed of an organic fiber cord and allows providing improved durability of the tire and weight reduction and a reduction in rolling resistance of the tire in a compatible manner. A belt layer (7) disposed on an outer circumferential side of a carcass layer in a tread portion (1) is made of a monofilament wire having a wire diameter of 0.30 mm or more and 0.45 mm or less. A belt reinforcing layer (8) disposed on an outer circumferential side of the belt layer (7) is made of a belt reinforcing cord made of a polyethylene terephthalate fiber and having an intermediate elongation under 2.0 cN/dtex load of from 2.0% to 4.0%. Circumferential portions of a strip (S) in which belt reinforcing cords (8c) are arranged are disposed at intervals in a tire width direction.
