Each of the closed sipesincludes a sipe bottom, a first endand a second end, a first sipe piece, a second sipe piece, a third sipe piece, and at least one tie bar. The closed sipesaligned in the tire axial direction overlap each other in the tire axial direction and a tire circumferential direction. The tie barincludes a first tie bar. A center, in a sipe length direction, of the first tie baris disposed closer to a first intersecting portionthan a center, in a length direction, of the first sipe pieceis. A distance from the first tie barto the first intersecting portionis not greater than 25% of a length of the first sipe piece
