Abstract:
A tire comprises a tread portion 2 comprising blocks 20. At least one of the blocks has a first block wall (25a), a second block wall (25b), and a first region (26a) and a second region (26b) divided by a crossing sipe 30. In a plan view, the first and second block walls (25a) and (25b) are each formed in a convex V-shape so as to have an apex portion 27 protruding toward the outside of the block. The crossing sipe 30 has a first end (28a) positioned on a first side of the apex portion 27 of the first block wall (25a) and a second end (28b) positioned on a second side of the apex portion 27 of the second block wall (25b) in the tire circumferential direction. The first and second regions (26a) and (26b) each have a closed sipe 38 having both ends terminating within the region.
