PROBLEM TO BE SOLVED: To rapidly improve on-ice performance by making a tread pattern appropriate. SOLUTION: This pneumatic tire is constituted so that a block group G<SB>B</SB>made as a plurality of independent small blocks 3 divided by grooves 2 are thickly arranged with each other is provided at least at part of a tread part 1 and block rows or land part rows are formed of the small blocks 3 of the block group G<SB>B</SB>. The small blocks 3 are respectively formed into a single shape and in the same size each other, and at least one groove 4 in the radial direction extending in the depth direction toward a surface of the groove 2 from a surface of the small block 3 and recessed inward from a peripheral surface C of the small block 3 is formed on the peripheral surface C of the small block 3.
