PROBLEM TO BE SOLVED: To provide a pneumatic tire that can improve a snow road performance while maintaining a steering stability when traveling on a dry road, by maintaining block rigidity even when sipes are formed in land blocks. SOLUTION: The pneumatic tire includes a land block 13 formed in a tread by a side circumferential groove 5 and a lateral groove 11 crossing the side circumferential groove 5. In the land block 13, a narrow lateral groove 17 extending in a tire width direction, and narrow longitudinal grooves 19 and 21 extending in a tire circumferential direction to cross the narrow lateral groove 17, which both ends in the circumferential direction are terminated inside the land block 13, are formed.
