A tire can include a block having a recess. The recess can include a first opening on a tread side and a second opening on a side wall face side. The first opening can include a pair of first edges extending from a first vertex to the side wall face side so as to form a V-shaped edge on the tread. The second opening can include a pair of second edges that can extend from a second vertex on the side wall face, and can be connected to the pair of first edges at intersection points. One of the pair of second edges can include a second edge body that can extend on a straight line from the second vertex to the intersection point, and a second edge subsidiary portion that can be bent so as to widen the second opening.
