PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of suppressing partial wear generated on an upper edge part of a rib-shaped land part along a zigzag groove and enhancing the durability by realizing an adequate tread pattern. SOLUTION: A center main groove 2 as a zigzag groove extending along the tire circumferential direction while being bent in a zigzag manner and a pair of side main grooves 3a, 3b located on both sides of the center main groove 2 and extending along the tire circumferential direction are arranged on a tread part 1. A pair of center land parts 4a, 4b are demarcated between the center main groove 2 and the side main grooves 3a, 3b. The center land parts 4a, 4b have stepped land parts 7a, 7b having a recessed section extending across the center land parts 4a, 4b between a first apex 6 of a bent part 5 of the center main groove 2 and the side main grooves 3a, 3b.
