TIRE

Snow road performance on a packed-snow road is enhanced. [0002] A tire 1 includes a block 3 having a recess 5. The recess 5 includes a first opening 6 on a tread 3a side and a second opening 7 on a side wall face 3b side. The first opening 6 includes a pair of first edges 9 extending from a first vertex 8 to the side wall face 3b side so as to form a V-shaped edge on the tread 3a. The second opening 7 includes a pair of second edges 12 that extend from a second vertex 10 on the side wall face 3b, and are connected to the pair of first edges 9 at intersection points 11. At least one of the pair of second edges 12 includes a second edge body 13 extending on a straight line from the second vertex 10 to the intersection point 11, and a second edge subsidiary portion 14 that is bent so as to widen the second opening 7.
