Problem: To provide a pneumatic tire that is advantageous in improving the traction performance (driving force transmission performance) on snowy and icy road surfaces and wet road surfaces, while maintaining steering stability on dry road surfaces. Resolution Means: The blocks 18 arranged in the tread center region 22 that is X% (30 ‰¤ X ‰¤ 70) of the tread contact width TW with the tire equator C as center are formed elongated in the tire circumferential direction so that the block ratio (S1/S2) is not less than 1.5. At least one end in the longitudinal direction of the sipes 20 provided in the blocks 18 connects to a longitudinal groove 14. A protrusion 30 and a recess 32 that can engage with each other are provided on the sipe wall surfaces that face each other constituting the sipes 20, at the end portion in the longitudinal direction of the sipes 20 that connect with the longitudinal groove 14. |
