PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of improving on-ice brake performance of tires.SOLUTION: A pneumatic tire 1 comprises, on a tread surface, land parts 31 to 33 each having a rib or a plurality of blocks. The land parts 31 to 33 further comprise, on a ground contact face, a plurality of shallow hairline grooves 7 and a plurality of recesses 8. When it is defined that a region of a central part 50[%] of the continuous ground contact face in the land parts 31 to 33 in a tire width direction is a central region, and that regions of right and left end parts 25[%] in the tire width direction are end regions, the relationship between an opening area ratio Se of the recesses 8 in the end regions ERs in the tire width direction and an opening area ratio Sc of the recesses 8 in the central region in the tire width direction for one continuous ground contact face is to be Sc<Se.SELECTED DRAWING: Figure 3 |
