摘要： 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.

摘要： A tire tread is provided having a layered design that includes bridged and unbridged circumferential grooves during earlier stages of tread life while transverse and unbridged circumferential grooves are provided at later stages of tread life. Together, the combination of grooves can provide desired wet adherence performance without unacceptable compromises of tread wear and/or rolling resistance. Pockets can also be provided at the end of the transverse grooves to increase the volume available for receipt of water during wet traction.
