An object of the present invention is to provide a pneumatic tire capable of ensuring both of the ice braking performance and the ice turning performance while increasing the dry steering stability performance. To achieve the above object, a sipe extending in a width direction of the tire is formed a land portion, the sipe having: pluralities of wide portions each having an inclined plane that begins from the tread surface of a road surface, and terminates in the half way of a sipe wall while inclining so that a sipe width decreases toward the groove bottom of the sipe, and a pair of side faces connecting the inclined plane and the sipe wall therebetween, wherein the pluralities of wide portions are located alternately on both sipe walls along a longitudinal direction of the sipe.
