Abstract
Two open sipes are formed at a tire circumferential direction central side of a block, and closed sipes are formed in the block at both tire circumferential direction sides of the two open sipes. The depth of the open sipes is set in a range of 50 to 70% times the depth of a first circumferential direction main groove, and the depth dimension of the closed sipe is set in a range of 105 to 140% times the depth dimension of the open sipes. Accordingly high performance on ice is obtained while securing block rigidity.
