PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of improving traveling performance on an iced road surface by uniforming ground contact pressure in blocks without excessively locally reducing the rigidity of the blocks. SOLUTION: The pneumatic tire having the blocks 1 on the tread surface comprises surface sipes 11 formed on the surfaces 1a of the blocks 1, wall surface sipes 12 formed on wall surfaces 1b of the blocks 1 and extending in the direction crossing the surface sipes 11, and wall surface sipes 13 formed on wall surfaces 1c adjacent to the wall surfaces 1b and extending in the direction crossing the surface sipes 11 and the wall surface sipes 12.
