Abstract:
Provided is a pneumatic tire. Center blocks provided in a center region of a tread portion are arrayed and form pairs across inclined grooves that are inclined with respect to a tire circumferential direction. Each one of the center blocks extends across a tire equator from one side to the other side of the tire equator. Each one of the center block includes a cut formed of a first wall and a second wall connected in a V-shape in a tread surface. The first wall extends at an angle within ±20° with respect to the tire circumferential direction in the tread surface, and the second wall extends at an angle within ±10° with respect to a tire lateral direction. Each one of wall surface angles of the first wall and the second wall is larger than a wall surface angle of a wall surface provided with the cut.
