PROBLEM TO BE SOLVED: To provide a pneumatic tire reducing noise due to a tread pattern while satisfactorily maintaining drainage performance. SOLUTION: In the pneumatic tire whose front and rear installation directions when installed into a vehicle are designated, three main grooves 11-13 extended in the tire circumferential direction are disposed in a tread section 1. Among these, the center position of the center main groove 12 is arranged at a position displaced from a tire equator CL toward the outside of the vehicle. Four rows of land sections 20-50 are divided by the main grooves 11-13. Narrow grooves 31 and 41 extended in the tire circumferential direction, and a plurality of inclined grooves 32 and 42 extended outwardly in a tire width direction from the narrow grooves are disposed in two rows of center land sections 30 and 40 located on the tire equator CL in the tread section 1. The width of the center land section 30 on the outside of the vehicle is larger than the width of the center land section 40 on the inside of the vehicle. A plurality of lug grooves 22 and 52 extended in the tire width direction are respectively disposed in two row of shoulder land sections 20 and 50 located on the shoulder side of the tread section 1. These lug grooves 22 and 52 are not communicated with the main grooves 11 and 13. COPYRIGHT: (C)2011,JPO&INPIT |
