PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of improving braking performance on a dry road surface, while ensuring steering stability on a wet road surface or an ice road surface. SOLUTION: On a tread TS, the pneumatic tire 1 is arranged with a plurality of thin holes extending inward in a tire diametrical direction from the tread TS in a block 7 divided by a plurality of circumferential direction grooves extending in a tire circumferential direction, and a plurality of width direction grooves 5 extending in a tread width direction. An opening part of end portion thin holes 9a which are the thin holes 9 disposed at a front end portion 11A and a rear end portion 11B in the tire circumferential direction in the block 7 is smaller than an opening part of center thin holes 9b which are the thin holes 9 disposed at a center portion 11C in the tire circumferential direction in the block 7.
