Abstract:
A tire that can improve braking performance on a dry road surface and wet performance is provided. The tire includes a tread portion 2. The tread portion 2 includes a shoulder land portion 5 disposed at an endmost tread edge side. The shoulder land portion 5 has a plurality of shoulder lateral grooves 10 that fully traverse the shoulder land portion 5. Each shoulder lateral groove 10 includes, in a transverse cross-section orthogonal to a longitudinal direction thereof, a bottom portion 11, a groove wall main body 12 extending from the bottom portion 11 outward in a tire radial direction, and a chamfered portion 15 between a ground-contact surface of the shoulder land portion 5 and the groove wall main body 12. The chamfered portion 15 is titled at an angle of 5 to 30° relative to a tread profile 13 obtained by extending the ground-contact surface.
