PROBLEM TO BE SOLVED: To provide a pneumatic tire in which radiation performance of a tread is enhanced while suppressing increase in total volume of grooves.SOLUTION: In a pneumatic tire, narrow grooves, which extend obliquely in a tire circumferential direction and have groove width smaller than groove depth, are provided on a tread surface at intervals in the tire circumferential direction. In one end portion of the narrow grooves, inflow portions, which extend in the tire circumferential direction, communicate with the narrow grooves at one end and terminate at the other end, are provided on groove wall faces, which are provided at a side of a termination point of tire circumferential direction components of a first vector going from the one end of the narrow grooves to the other end of the narrow grooves, out of groove wall faces of the narrow grooves opposing in the tire circumferential direction. |
