PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of suppressing occurrence of a hydro-planing phenomenon by improving drainability.SOLUTION: A groove bottom of a main groove is provided with at least one protrusion protruding from the groove bottom and elongated along the main groove. A streak part comprising a plurality of projections or depressions inclined with respect to an extension direction of the main groove is formed on an inner surface of the main groove provided with the protrusion. Inclination directions of the streak parts on both the sides of the groove center of the main groove are set different from each other, and the streak part is inclined to the side of the groove center toward the side opposite to a rotational direction. |
