PROBLEM TO BE SOLVED: To improve cut-chip resistance by preventing the bite-in of a stone or the like into a groove without impairing on-snow performance.SOLUTION: A pneumatic tire has a tread part 2, a center land part row 3, and shoulder land part rows 4, 4 which are arranged at both sides of the center land part row 3. The pneumatic tire also comprises: outside main grooves 11 which extend to a circumferential direction at both sides with a tire equator CL sandwiched, and partition the center land part row 3 and the shoulder land part rows 4; a plurality of center lateral grooves 12 which are formed at the center land part row 3, extend to a tire width direction between a pair of the outside main grooves 11, 11, and communicates with the outside main grooves 11; a plurality of center blocks 31 in which the center land part row 3 is partitioned by the center lateral grooves 12; and first and second protrusions 50, 60 which extend from at least either of the outside main grooves 11 and the center lateral grooves 12, and arranged so as to surround first and second corner parts 34, 35 which adjoin the outside main grooves 11 of the center blocks 31. |
