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 to a vehicle is designated, first to third main grooves 11, 12 and 13 extending in a circumferential direction and a circumferential-direction 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. Groove widths GWto GWthat the main grooves 11 to 13 respectively have are 8 mm to 18 mm, and while the ratio of the maximum value to the minimum value among the groove widths GWto GWis 1.0 to 1.2 and 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, the inclination directions of the first center lug groove and the second center lug groove are both directions opposite to that of the first shoulder lug groove.SELECTED DRAWING: Figure 2 |
