摘要： Wet performance and partial wear resistance of a tire are improved, and a noise generated during running of the tire is reduced.At a tread portion 2, a plurality of land portions 20, 30, and 40 is defined by circumferential main grooves 10 and 11 extending in a zig-zag manner in a tire circumferential direction. In the center land portion 20 and the second land portion 30, a plurality of hexagonal blocks 21B, 22B, 23B, and 30B is provided, each gradually expanding to the both sides in the tire width direction from the both end portions in the tire circumferential direction toward the center. In the center land portion 20, the plurality of hexagonal blocks 21B, 22B, and 23B is arranged so as to be brought close to each other in the tire width direction while sandwiching a circumferential thin groove 24 extending in a zig-zag manner in the tire circumferential direction and to be defined by lug grooves 25, 26, and 27 in the tire circumferential direction. In the second land portion 30, the plurality of hexagonal blocks 30B is arranged so as to continue in the tire circumferential direction while sandwiching a sipe 31, and formed in a rib shape continuous in a ground-contacting surface.
