Abstract
A pneumatic tire structured such that a sipe is formed in a land portion of a tread surface. The sipe has a wide portion extending along a longitudinal direction at least at one position in a depth direction. The wide portion is structured by alternately arranging concave portions which are smaller in the longitudinal direction and the depth direction than the sipe, in both sides of a sipe wall surface along the longitudinal direction of the sipe.
