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 includes a tread portion 10. In the tread portion 10, a shoulder land portion 40A and a center land portion 40B are formed from a tire equator line toward outside in the tire width direction using as a basis, a quarter point portion centered on a position distant by quarter the width in a tire width direction of the tread portion 10. In the shoulder land portion 40A, there is formed a width direction groove that extends from a land portion 10E of the tread portion 10 toward inside in the tire width direction and terminates in the shoulder land portion 40A. In the center land portion 40B, there is formed an inclining groove that extends in a direction of inclining toward a tire circumferential direction and has both end portions in the center land portion. The width direction groove has, on at least a part thereof, an inclining portion inclining forward in a tire rotating direction and an extending direction of the inclining groove is inclined further to outside in the tire width direction than the tire rotating direction. |
