PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of simultaneously satisfying the wet performance and the noise performance. SOLUTION: A plurality of inclined lug grooves 2 communicated with right and left shoulder ends EO and EI with the angleθ1 with respect to the tire circumferential direction at the shoulder ends EO and EI being 70-90 deg., and a plurality of inclined main grooves 3 with the angleθ2 of the tire circumferential direction being 15-35 deg. are provided in a tread surface 1. The inclined lug grooves 2 have a curved shape in which the angle to the tire circumferential direction is gradually decreased from the shoulder end EO on the outer side when the tire is fitted to a vehicle toward the tread center line CL, a point P of inflection is provided in the vicinity of the tread center, and the angle to the tire circumferential direction is gradually increased toward the shoulder end EI on the inner side when the tire is fitted from the point P of inflection, the inclined main grooves 3 have the length across at least eight rows of spaces 4 demarcated by the inclined lug grooves 2, and at least four inclined main grooves 3 are arranged in each space 4. |
