Abstract
Provided is a pneumatic tire whose braking performance on ice and partial-wear resistance can be improved. SipesX provided in a ribon a tire equatorial plane TE are formed in such a three-dimensional shape that the amount at which the ribcollapses due to an external force is smaller in the tire rotational direction than in a direction opposite to the tire rotational direction. In each blockin each shoulder regionS, sipesMa in a block tread-in side portionA are each formed in such a three-dimensional shape that the amount at which the block, if entirely provided with the sipesMa, collapses due to an external force will be smaller in the tire rotational direction than in the direction opposite to the tire rotational direction. SipesMb in a block kick-out side portionB are each formed in such a three-dimensional shape that the amount at which the block, if entirely provided with the sipesMb, collapses due to an external force will be smaller in the direction opposite to the tire rotational direction than in the tire rotational direction.
