摘要:
Provided is a tire having improved braking performance while maintaining noise performance. The tire includes a tread portion 2 having a designated rotation direction R. The tread portion 2 includes a first tread end T1, first inclined grooves 5, and first land portions 7. Each of the first inclined grooves 5 includes a first groove wall 11 on a leading edge side in the rotation direction R and a second groove wall 12 on a trailing edge side in the rotation direction R. A first chamfered portion 13 is formed on the first groove wall 11, and a second chamfered portion 14 is formed on the second groove wall 12. In a cross-section orthogonal to a groove center line of the first inclined groove 5, a chamfered area S1 of the first chamfered portion 13 is larger than a chamfered area S2 of the second chamfered portion 14.
