Abstract: Provided is a heavy load tire that includes: the first belt layer including a cord extending in the tire circumferential direction; the second belt layer including a cord extending to be inclined with respect to the tire circumferential direction; and the third belt layer including a cord extending to be inclined at an angle of 30° or less with respect to the tire circumferential direction in a direction opposite to that of the cord of the second belt layer. The first, the second, and the third belt layer are arranged in the stated order from the inner side to the outer side in the tire radial direction. The third belt layer has a width w3 that is 80% or more of a tread width w, and the second belt layer has a width w2. The width w2 and the width w3 satisfy the relation w2

Abstract: A tire 1 includes plural land portions 40 formed on a tread portion 10. The plural land portions 40 are segmented by a circumferential direction groove 30 extending in a tire circumferential direction L and a width direction groove 20, or segmented by an end portion 10E of the tread portion 10 in the tire width direction W and the width direction groove 20. A length of the width direction groove 20 in the tire width direction W is not less than 30% of a length of the tread portion 10 in the tire width direction W. The width direction groove 20 has at least one angled portion 50A/50B configured to be bent toward an opposite direction to a tire rotational direction R on at least one side of a tire equator line CL.

Abstract: 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.

Abstract: A tire 1 includes plural land portions 40 formed on a tread portion 10. The plural land portions 40 are segmented by a circumferential direction groove 30 extending in a tire circumferential direction L and a width direction groove 20, or segmented by an end portion 10E of the tread portion 10 in the tire width direction W and the width direction groove 20. A length of the width direction groove 20 in the tire width direction W is not less than 30% of a length of the tread portion 10 in the tire width direction W. The width direction groove 20 has at least one angled portion 50A/50B configured to be bent toward an opposite direction to a tire rotational direction R on at least one side of a tire equator line CL.
Abstract translation: 轮胎1包括形成在胎面部10上的多个陆部40.多个陆部40由沿轮胎周向L和宽度方向槽20延伸的圆周方向槽30分割，或者由端部10E的端部10E分割 胎面部10在轮胎宽度方向W上和宽度方向槽20.宽度方向槽20在轮胎宽度方向W上的长度不小于胎面部10在轮胎宽度方向上的长度的30％ 宽度方向槽20具有至少一个成角度部分50A / 50B，其被构造成在轮胎赤道线CL的至少一侧上朝向与轮胎旋转方向R相反的方向弯曲。

Abstract: A first belt layer includes a cord extending at an inclination angle of greater than 45° with respect to the tire circumferential direction, a second belt layer includes a cord extending in the tire circumferential direction, and a third belt layer includes a cord extending at an inclination angle of 30° or less in the opposite direction from the cord of the first belt layer with respect to the tire circumferential direction. The belt layers are arranged in order, with the first belt layer furthest inward in the tire radial direction, on the outer circumferential side of a crown region of a carcass extending toroidally between a pair of bead portions. The third belt layer width w3 is 80% or more of the tread width w, and w2
