<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire improving pass-by noise performance without impairing wet performance. <P>SOLUTION: In the pneumatic tire in which a rib-shaped land continuous in a circumferential direction is divided in treads by a plurality of circumferential grooves extending in a tire circumferential direction, the groove volume obtained by summing groove volumes of all the circumferential grooves of a vehicle inner side from a tire equatorial plane when mounted on a vehicle is larger than the groove volume obtained by summing the groove volumes of all the circumferential grooves of a vehicle outer side. An inclined groove having one end opened to the circumferential groove and the other end terminating in a rib shaped land is provided to at least one circumferential groove. An inclination angle of the inclined groove relative to a tire width direction is larger than an inclination angle of a shoulder groove having one end opened to a tread end and the other end terminating in a shoulder land relative to the tire width direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
