PROBLEM TO BE SOLVED: To improve mud performance and dart performance.SOLUTION: A pneumatic tire 1 comprises shoulder blocks 3 and center blocks 4. A tread 3a of each shoulder block 3 comprises a gradual inclination part 6 extending in inside of a tire axial direction by an angle of 15 degree or less, from a tread end Te side to the tire axial direction, and a sharp inclination part 7 continuous to the gradual inclination part 6 and having a larger angle larger than that of the gradual inclination part 6 to the tire axial direction. A tread 4a of each center block 4 has a first inclination part 15 which is inclined in a direction same to that of the sharp inclination part 7 of the shoulder block 3, and a second inclination part 16 continuous to the first inclination part 15 and inclined in an opposite direction of that of the first inclination part 15 and in the tread end Te side. The first inclination part 15 has length in a tire peripheral direction longer than that of the second inclination part 16. |
