Abstract

A tire includes a tread portion 2 having a designated rotation direction R. The tread portion 2 includes a first tread end T1, a first middle position 10, and first inclined grooves 5. An inner end 5i of each first inclined groove 5 in a tire axial direction is located on a tire equator C side with respect to the first middle position 10. In each first inclined groove 5, an angle relative to a tire circumferential direction at the inner end 5i is smaller than that at the first middle position 10. Each first inclined groove 5 includes a first groove wall 11 on a leading edge side and a second groove wall 12. In an inner region 5A of each first inclined groove 5, the second groove wall 12 includes a chamfered portion 15. In a cross-section orthogonal to a groove center line of the first inclined groove 5, a chamfered area of the chamfered portion 15 increases toward the inner end 5i side.
