<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire particularly improved in uneven wear resistance of blocks dividingly formed in the vicinity of a tire equator surface, without deteriorating performance on ice. <P>SOLUTION: Block division is performed by disposing, on a tread surface 1, a plurality of circumferential grooves extended in a tread circumferential direction; and a plurality of lateral grooves extended in a tread width direction across these circumferential grooves. A sipe 10 located close to the tire equator surface and a sipe 11 located close to a tread end, are disposed on the blocks interposing therebetween the central circumferential groove located in the vicinity of the tire equator surface, respectively. Both ends of the sipe 10 close to the tire equator surface are terminated in the blocks, and at least one end of the sipe 11 close to the tread end opens into the circumferential grooves or the lateral grooves. <P>COPYRIGHT: (C)2011,JPO&INPIT |
