Abstract
A pneumatic tire includes a tread portion molded by sectors divided in a tire circumferential direction. The pneumatic tire includes circumferential grooves, rows of land portions, and sipes. The circumferential grooves extend in the tire circumferential direction in the tread portion. The rows of land portions are defined by the circumferential grooves. The sipes extend in a tire width direction in at least one row of the rows of land portions. The sipes include at least one shallow bottom sipe and regular sipes. The at least one shallow bottom sipe is disposed in a boundary region including a dividing position of each of the sectors. The regular sipes are disposed at positions more separated from the dividing position of each of the sectors than the at least one shallow bottom sipe. The at least one shallow bottom sipe is shallower than the regular sipes.
