The circumferential grooves include an inboard shoulder circumferential groove located nearest to the inboard tread edge in the circumferential grooves. The land portions include an inboard shoulder land portion disposed axially outward of the inboard shoulder circumferential groove and having a ground contact surface with the smallest axial width in the land portions. The inboard shoulder land portion is provided with inboard shoulder lateral grooves and inboard shoulder sipes. The inboard shoulder lateral grooves include inner ends away from the inboard shoulder circumferential groove. The inboard shoulder lateral grooves extend axially outward from the inner ends to a location beyond the inboard tread edge. The inboard shoulder sipes extends from the inboard shoulder circumferential groove to a location beyond the inboard tread edge.
