  "textContent": "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 in a groove depth direction to form a serrated surface having a plurality of tip portions between the first surfaces and the second surfaces, and the first surfaces are longer than the second surfaces such that each of the plurality of tip portions has an acute angle.",
