<p><P>PROBLEM TO BE SOLVED: To provide a pneumatic tire with a sipe capable of restraining deterioration of block rigidity near an end of the sipe, and restraining deterioration of a performance when abrasion is progressed. <P>SOLUTION: A plurality of projections 22 are formed on one wall 20A of a sipe 20. The projections 22 are formed on both of the ends of the sipe, not on a center. When a block 18 is grounded and fell over by rolling a pneumatic tire, a plurality of the projections 22 are strongly pressed to the opposed wall, and small blocks 18 divided by the sipe 20 are supported by each other on the sipe end. Accordingly, deterioration of block rigidity near the end of the sipe 20 can be restrained, and the depth of the sipe 20 is constant, so as to restrain deterioration of a performance when abrasion is progressed. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
