摘要 PROBLEM TO BE SOLVED: To reduce shear force generated between a region in the vicinity of a tire equator line CL and a region in the vicinity of an end portion in a tire width direction W.SOLUTION: A tire 1 related to the present invention has a plurality of land portions 40, at a tread portion 10, comparted by a circumferential groove 30 extending in a tire circumferential direction L or an end portion 10E of the tread portion 10 and a width direction groove 20 extending in a tire width direction W constituted in such a manner that the length of the groove 20 in the tire width direction W is 30% or more than the length of the tread portion 10 in the tire width direction W. The width direction groove 20 has on at least one side of the tire equator line CL, a bending portion 52A constituted to bend so as to protrude at least in one tire rotating direction. The land portions 40 have a ground contact surface 40z and a width direction side wall 40x formed by the width direction groove 20. An angle between the ground contact surface and the width direction side wall at a place closer to the tire equator line than the bending portion 50A is different from an angle between the ground contact surface and the width direction side wall in the bending portion 50A.
