The center main groovecomprises first oblique groove segmentsA inclined with respect to the tire circumferential direction to one axial direction at an angle, and second oblique groove segmentsB inclined with respect to the tire circumferential direction to the other axial direction at an angle less than the angle of the first oblique groove segments. The crown land portionis divided into hexagonal crown blocksby crown lateral groovesextending between axially inwardly protruding zigzag vertex portions of the center main grooveand axially outwardly protruding zigzag vertex portions of the middle main groove. The crown lateral groovesand the first oblique groove segmentsA are inclined with respect to the tire axial direction to one circumferential direction.
