PROBLEM TO BE SOLVED: To provide a pneumatic tire, of which the driving stability on the snow after the occurrence of traveling wearing is improved without losing the driving stability on a dry road. SOLUTION: The pneumatic tire comprises a circularly formed tread, a pair of side walls arranged to extend inward from both sides of the tread in the radial direction of the tire, and beads formed continuous with the side walls in the radial direction of the tire. The tread has a treading surface on which blocks 1 are formed, where the blocks 1 are sectioned by a plurality of main grooves extending in the circumferential direction and by transverse grooves crossing the main grooves, and each block 1 has cipes 3. The block 1 comprises a pair of acute angle block corners 2 opposed to each other in the circumferential direction, a pair of small blocks 4 sectioned by a pair of the acute angle block corners 2 and by two cipes 3, and a central block 5 sandwiched between the small blocks 4, each of which is smaller than the central block.
