A pneumatic tire includes a carcass, a tread portion and a belt layer having a first inclined belt ply, circumferential direction belt ply, and second inclined belt ply. Ground contact edge side belt plies extend from tire width direction end portions of the second inclined belt ply toward tire width direction outsides, at a tire radial direction outside of the carcass. With respect to a tire circumferential direction, an angle of cords of the first inclined belt ply is from 45° to 60°, an angle of a cord of the circumferential direction belt ply is 5° or less, an angle of cords of the second inclined belt ply is from 30° to 60°, and an angle of cords of the ground contact edge side belt plies exceeds 5° and is 30° or less. A distance dimension of the ground contact edge side belt plies is 80% or more of a ground contact width.
