Abstract:
In a pneumatic tire, center land portions include a circumferential narrow groove extending in the tire circumferential direction so as to partition the center land portions in a tire width direction; a plurality of lug grooves disposed in each region of each of the center land portions partitioned by the circumferential narrow groove, extending in the tire width direction, so as to partition each of the regions of the center land portions in the tire circumferential direction; and a plurality of blocks partitioned by the circumferential narrow groove and the plurality of lug grooves. Blocks of the center land portions include one open sipe extending in the tire width direction so as to partition the blocks in the tire circumferential direction, and three or more closed sipes disposed in each of the regions of each of the blocks partitioned by the open sipe.
