Abstract: Provided is a pneumatic tire improved in on-ice friction properties of the tire, which is excellent in on-ice performance, in particular, on-ice braking performance. The pneumatic tire according to the present invention includes, in a tread portion surface located between both tread ends, a plurality of main grooves extending in a tire circumferential direction; a plurality of lateral grooves extending in a tire width direction, the lateral grooves each having one bent point so as to be in a convex shape in the tire circumferential direction between the main grooves and/or between the main groove and the tread end, the plurality of main grooves and the plurality of lateral grooves partition-forming a plurality of blocks each including a circumferential protrusion in a shape conforming to the convex shape of the lateral groove, the blocks each including at least one lateral sipe extending in the tire width direction in a shape conforming to the lateral grooves, in which the lateral sipe is equal in tire-width-direction dimension to the block having the lateral sipe disposed therein when both are projected onto the same plane which includes the tire rotation axis and is perpendicular to the block surface.
