Each first sipe includes a tie-bar locally raising radially outwardly from the sipe bottom to divide the first sipe into first and second portions. The sipe bottoms of the first and second portions extend in a zigzag shape in a cross-section parallel to the ground contact surface. The sipe bottom of the first portion communicates with a first widening portion having a circular cross-sectional shape with a groove width greater than a width of the first portion and extending in a zigzag shape along the first portion. The sipe bottom of the second portion communicates with a second widening portion having a circular cross-sectional shape with a groove width greater than a width of the second portion and extending in a zigzag shape along the second portion. The first and second widening portions do not communicate with each other.",
