PROBLEM TO BE SOLVED: To provide a pneumatic tire that can make both steering stability performance on a dry road surface and a wet road surface compatible at high level.SOLUTION: A pneumatic tire has a plurality of main grooves 3-5 continuously extending in a tire circumference direction and a plurality of land parts 6-9 partitioned by the main grooves 3-5 provided at a tread part 2. In a first center land part 8 are not provided grooves whose widths are equal to or more than 2 mm but are provided a plurality of first center sipes 10 whose widths are less than 2 mm. In a second center land part 9 are not provided grooves whose widths are equal to or more than 2 mm but are provided a plurality of second center sipes 11 whose widths are less than 2 mm. The first center sipes 10 extend from a center main groove 5 to one shoulder main groove 3, and the second center sipes 11 extend from the center main groove 5 to the other shoulder main groove 4. The first center sipes 10 incline toward one direction relative to a tire shaft direction and the second center sipes 11 incline toward the same direction as the first center sipes 10 relative to the tire shaft direction.SELECTED DRAWING: Figure 1 |
