TYRE

A tyre includes a tread portion having a tread surface being provided with a plurality of lateral grooves extending in a tyre axial direction. In a cross-sectional view perpendicular to a longitudinal direction of the at least one of the plurality of lateral grooves, the at least one of the plurality of lateral grooves includes a pair of groove walls and a groove bottom. At least one of the pair of groove walls includes a serrated portion including first surfaces and second surfaces that are arranged alternately. Each first surface is inclined outwardly in a groove width direction toward the groove bottom and has a radially inner end thereof, and each second surface extends substantially parallel with the tread surface from the radially inner end of a respective one of the first surfaces toward a groove centerline of the at least one of the plurality of lateral grooves.
