A first inclined belt ply (16), a circumferential direction belt ply (18), and a second inclined belt ply (20) are disposed in this sequence, and ground contact edge side belt plies (28) are disposed extending from tire width direction end portions of the second inclined belt ply (20) toward tire width direction outer sides, at a tire radial direction outer side of a carcass. With respect to a tire circumferential direction, an angle of cords of the first inclined belt ply (16) is from 45° to 60°, an angle of a cord of the circumferential direction belt ply (18) is 5° or less, an angle of cords of the second inclined belt ply (20) is from 30° to 60°, and an angle of cords of the ground contact edge side belt plies (28) exceeds 5° and is 30° or less. A distance dimension W4 of the ground contact edge side belt plies (28) is 80% or more of a ground contact width TW, and the cords of the second inclined belt ply (20) and the cords of the ground contact edge side belt plies (28) are inclined in opposite directions to each other with respect to the tire circumferential direction. |
