PROBLEM TO BE SOLVED: To provide a pneumatic tire which improves on-snow operation stability performance on a high-speed region.SOLUTION: An inner land part 13b divided by two circumferential direction grooves 12c, 12a formed so as to be elongated along a tire circumferential direction and an inclination lug groove 14b which divides the inner land part 13b into a plurality of blocks 15b, has a groove depth which shallower than the groove depth of the circumferential direction groove 12c, 12a and is elongated in a direction inclined to the tire circumferential direction and the tire width direction are disposed on the surface of a tread 11. At the same time, one inclination sipe 16p which is inclined in the same direction as the inclination lug groove 14b and has both edges opened to the circumferential direction grooves 12c, 12a and a plurality of sub-sipes 16q, 16r of which one edge is opened to the circumferential direction grooves 12c, 12a, the inclination lug groove 14b or the inclination sipe 16p and the other edge is ended in the blocks 15a and is inclined in the direction opposite to the inclination sipe 16p are formed on the surface of the block 15b. |
