<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of improving a steering stability performance and noise performance. <P>SOLUTION: The pneumatic tire 1 includes, in a tread portion: at least four circumferential main grooves 21 to 24 extending in the tire circumferential direction; and a plurality of rib-like land portions 31 to 35 partitioned by the circumferential main grooves 21 to 24. Additionally, an outer side second land portion 32 includes: an L-shaped narrow groove 321 formed by connecting a width direction groove portion 3211 extending from an edge portion on an outer side in the tire width direction of the outer side second land portion 32 toward an inner side in the tire width direction, and a circumferential direction groove portion 3212 extending substantially parallel to the tire circumferential direction and terminating in an interior portion of the outer side second land portion 32; and a penetrating sipe 322 penetrating the outer side second land portion 32 in the tire width direction and intersecting the circumferential direction groove portion 3212. A plurality of L-shaped narrow grooves 321 and a plurality of penetrating sipes 322 are disposed in a tire circumferential direction with a predetermined interval. Also, the adjoining L-shaped narrow grooves 321 and 321 are disposed independently from each other. <P>COPYRIGHT: (C)2013,JPO&INPIT |
