PNEUMATIC TIRE

Provided is a pneumatic tire that allows enhancing braking performance on wet road surfaces and snowy road surfaces and reducing the occurrence of poor appearance, without changing the appearance of a tire. In the pneumatic tire, a tread portion including a plurality of rows of land portions defined by a plurality of circumferential grooves extending in a tire circumferential direction is formed by a plurality of sectors divided in the tire circumferential direction, a plurality of sipes extending in a tire width direction formed in the land portions include a three-dimensional sipe, whose shape appearing on a tread surface changes along a sipe depth direction, and a two-dimensional sipe, whose shape appearing on the tread surface is constant along the sipe depth direction, and a ratio R1 of the number of the three-dimensional sipes with respect to the total number of the sipes in the first boundary region, which is within 15 mm on one side of a sector dividing position in the tire circumferential direction, and a ratio Rt of the number of the three-dimensional sipes with respect to the total number of the sipes in all of the tread portion satisfy the relationship R1 < Rt.
