<p>Provided is a pneumatic tire which can improve the braking performance on ice and the partial-wear resistance. Sipes (11X) provided in a rib (5) on the tire equatorial plane (TE) are arranged in a three-dimensional shape where the amount of collapse of the rib (5) by the external force becomes smaller in one rotational direction of the tire than in the other rotational direction of the tire. In the block (10) of a shoulder region (1S), the sipes (11Ma) on the block tread-in side (10A) have a three-dimensional shape where the amount of collapse of the block by the external force when the sipes (11Ma) are provided entirely in the block (10) becomes smaller in one rotational direction of the tire than in the other rotational direction of the tire, and the sipes (11Mb) on the block kick-out side (10B) have a three-dimensional shape where the amount of collapse of the block by the external force when the sipes (11Mb) are provided entirely in the block (10) becomes smaller in the other rotational direction of the tire than in one rotational direction of the tire.</p> |
