PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of reducing rolling resistance by suppressing the straw bag shape deformation of a block. SOLUTION: In the pneumatic tire provided with the block 1 on a tread surface, a wall surface 1b of the block 1 is divided into a plurality of small wall surfaces 5 by a boundary line 4 extended in the longitudinal direction of an adjoining groove, and each of the small wall surfaces 5 is twisted in the same direction, and thereby projecting parts 6 projected toward the groove are formed on the wall surface 1b. Thereby, a load when the block 1 is compressed is dispersed, and the rolling resistance can be reduced by suppressing the straw bag shape deformation of the block 1. COPYRIGHT: (C)2010,JPO&INPIT |
