摘要： The tire includes a tread portion having circumferential grooves extending in a tire circumferential direction and land regions demarcated by the circumferential grooves. The circumferential grooves include a first circumferential groove and a second circumferential groove adjacent to the first circumferential groove and having a width larger than the first circumferential groove. The land regions include a first land region demarcated between the first circumferential groove and the second circumferential groove. The first land region has lateral grooves extending in a tire axial direction and lateral sipes extending in the tire axial direction and each having a width smaller than that of each of the lateral grooves. A total value of the widths of the lateral grooves and the lateral sipes connected to the second circumferential grooves is smaller than a total value of the widths of the lateral grooves and the lateral sipes connected to the first circumferential grooves.

摘要： A block has a first wall surface formed from a position where a lateral groove is opened to a first circumferential groove toward an upstream side of an air flow, a second wall surface formed from a position where the lateral groove is opened to a second circumferential groove toward the upstream side of the air flow, and a block corner portion formed at a position where the lateral groove is opened to the second circumferential groove. A virtual surface obtained by extending the second wall surface on the upstream side intersects with the block corner portion on a downstream side or passes through a position in the second circumferential groove which is apart from the block corner portion in a tire width direction. A groove width of the first circumferential groove gradually increases toward the downstream side of the air flow at the first wall surface.

摘要： A method and apparatus for shielding critical faster-moving upper wheel surfaces from headwinds reduces vehicle propulsive counterforces needed to countervail mechanically magnified upper wheel drag forces combined with drag forces on the apparatus itself. The apparatus includes various upper wheel fairings of FIGS. 1-6. Each fairing shields a critical primary vehicle-drag-inducing upper wheel surface from headwinds otherwise impinging thereon.
