The first land portion includes a ground contact surface, a land sidewall on a first circumferential groove side, and a recess that opens across both the ground contact surface and the land sidewall. The recess has an opening defined by a V-shaped first edge and a V-shaped second edge respectively extending on the ground contact surface and the land sidewall. The recess has a circumferential maximum length L1 of from 6.0 to 9.0 mm. The recess has a maximum depth dl of from 15% to 40% of a maximum depth of the first circumferential groove. The recess has an axial maximum length L2 of from 3.0 to 5.0 times the depth dl.",
