TIRE

A tire comprises a tread portion provided with blocks including a first block provided with a plurality of sipes. Each sipe comprises a zigzag portion in a cross section perpendicular to the sipe length direction, and a zigzag portion in a cross section parallel to the ground contacting top surface of the first block. Each of the sipes is provided with at least one tie bar protruding radially outwardly from the bottom of the sipe and terminating without reaching the ground contacting top surface. The sipes includes a first sipe having the tie bar at a first position in the tire axial direction, and a second sipe having the tie bar at a second position in the tire axial direction different from the first position.
