PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of enhancing on-snow performance while suppressing generation of eccentric wear. SOLUTION: A groove wall 7 in which blocks 5 are divided by a lateral groove 4 is formed to a recession/projection-like wall surface such that a step surface side and a groove bottom side of the groove wall 7 are formed to the zigzag shape 14, 15 and are deviated by a half pitch in a tire width direction, and a trigonal pyramid-like projection part 8 and a reverse trigonal pyramid-like projection part 9 formed by ridge lines 16, 17 for connecting an apex 10 of a zigzag shape-like crest-folding part and an apex 11 of a bottom-folding part between both zigzag shapes 14, 15 and left and right bottom lines 18 connecting the apexes 12 of the bottom-folding part to each other at both sides are alternately continued in a tire width direction.
