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。
