Provided is a pneumatic tire. A belt cover layer made of an organic fiber cord spirally wound along the tire circumferential direction is provided on the outer circumferential side of a belt layer in a tread portion, and a polyethylene terephthalate fiber cord of which the elastic modulus under a load of 2.0 cN/dtex at 100° C. is in the range of 3.5 cN/(tex·%) to 5.5 cN/(tex·%) is used as the organic fiber cord. The coating rubber covering the organic fiber cord contains one or more of natural rubber, styrene-butadiene rubber, or butadiene rubber as a rubber component. The coating rubber is formed of a rubber composition in which the content of natural rubber in the rubber component is 50 mass % or more, and 5.0 parts by mass to 9.0 parts by mass of zinc oxide is blended per 100 parts by mass of the rubber component.
