PROBLEM TO BE SOLVED: To provide a pneumatic tire that can achieve both initial steering responsiveness and steering stability during turning.SOLUTION: The pneumatic tire has at a tread surface a plurality of circumferential main grooves extending continuously in a tread circumferential direction and a plurality of land parts partitioned by tread ends. In center lands formed on a tire equator surface are formed at a predetermined pitch length center sipes extending in a tread width direction, and spaces between the adjacent center sipes are continuous in the tread circumferential direction. In intermediate land parts, adjacent to both sides in the tread width direction of the center land parts through the circumferential main grooves, are formed at a predetermined pitch length intermediate sipes extending in the tread width direction, and spaces between the adjacent intermediate sipes are continuous in the tread circumferential direction. A pitch length of the intermediate sipes is longer than the pitch length of the center sipes, and both ends of the center sipes are opened to the circumferential main grooves.SELECTED DRAWING: Figure 1 |
