PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of improving wet performance, dry performance, uneven wear resistance, and antinoise performance in a balanced manner.SOLUTION: In a pneumatic tire whose mounting direction is designated, first to third main grooves 11 to 13 extending in a circumferential direction and a narrow groove 14 are disposed on a tread part 1 to be partitioned into first and second shoulder land parts 21 and 22, and first, second and third center land parts 31, 32 and 33; and first and second shoulder lug grooves 41 and 42, and first and second center lug grooves 51 and 52 are disposed on the tread part 1. Groove widths GWto GWthat the main grooves 11 to 13 respectively have are 8 mm to 18 mm, and the maximum value/minimum value among the groove widths GWto GWis 1.0 to 1.2. The ratio of a groove width GWof the circumferential-direction narrow groove to the minimum value among the groove widths GWto GWis 0.2 to 0.5, and while the inclination direction of the first center lug groove is a direction opposite to that of the first shoulder lug groove, the inclination direction of the second center lug groove is the same direction as that of the first shoulder lug groove.SELECTED DRAWING: Figure 2 |
