PROBLEM TO BE SOLVED: To provide a pneumatic tire further increased in braking performance while suppressing the lowering of the steering stability of a vehicle when providing a plurality of ribs linearly extending in the tire circumferential direction. SOLUTION: This pneumatic tire 1 includes a rib-shaped land part 40 formed of a plurality of ribs linearly extending in the tire circumferential direction R. The rib-shaped land part 40 includes a rib 10 and a rib 20 and a rib 30 which are formed on the inner side and outer side of the rib 10, respectively, when the tire is mounted on a vehicle and are partitioned by a sipe 50 and a sipe 60, respectively. The width of the rib 10 in the tread width direction WTR is smaller than the widths of the rib 20 and the rib 30 in the tread width direction WTR. The rib-shaped land part 40 is provided further to the inner side than the equator CL of the pneumatic tire 1 when the tire is mounted on the vehicle. COPYRIGHT: (C)2010,JPO&INPIT |
