Pneumatic tire

A pneumatic tire including multiple blocks formed on a tread face by a plurality of main grooves extending in a circumferential direction of the tire and by a plurality of sub grooves intersecting the main grooves, in which zigzag sipes extending in a width direction of the tire are provided on surfaces of the blocks,

• wherein the sipes are formed by
• shifting pitches of a zigzag shape on a tread face side of the sipe and a zigzag shape on a bottom side thereof in the width direction of the tire,
• and in the case of viewing concave and convex points according to a visual direction E along the circumferential direction of the tire, connecting a convex flexion point of the zigzag shape on the tread side and a concave flexion point of the zigzag shape on the bottom side which are facing each other, a concave flexion point of the zigzag shape on the tread side and a convex flexion point of the zigzag shape on the bottom side which are facing each other, and the convex points of the both zigzag shapes which are adjacent to each other, severally with edge lines, and
• interlinking the edge lines serially by planes in the width direction of the tire,
• wherein one of wall surfaces sectioned by the sipe is formed into a concavo-convex face A in which convex triangular pyramids and convex reverse triangular pyramids are alternately arranged in the width direction of the tire, and the other wall surface is formed into a concavo-convex face B in which concave triangular pyramids and concave reverse triangular pyramids are alternately arranged in the width direction of the tire, and
• wherein at least the concavo-convex faces A sectioned by the sipes are disposed in both outermost positions in the circumferential direction of the block to be oriented outward from the block.
