    摘要： A pneumatic tire including a tread portion, side wall portions, and bead portions, wherein the tread portion includes a plurality of circumferential grooves having a groove width of not less than 3.0 mm and which extend in a tire circumferential direction while meandering, and a plurality of lateral grooves having a groove width of not less than 3.0 mm and which communicate between a pair of circumferential grooves adjacent in a tire width direction. The circumferential grooves and the lateral grooves partition two rows of polygonal blocks formed by arranging a plurality of polygonal blocks, having a polygonal shape with not less than five corners, in a staggered manner along the tire circumferential direction. A polygonal rib extending in the tire circumferential direction is disposed between the two rows of polygonal blocks. The polygonal rib is adjacent to the two rows of polygonal blocks.

    摘要： Tire treads having one or more repeating pitches, each repeating pitch comprising individual pitches having tread blocks with sipes formed therein and each pitch having a pitch length of between 15 mm and 35 mm. Such treads may also have a weighted average sipe density Dw of between 10 mm−1 and 37 mm−1, which is determined through the disclosed Eq. 2 below. The tread blocks are also formed from a rubber composition based upon a diene elastomer, a plasticizing system and a cross-linking system, wherein the rubber composition has a glass transition temperature of between −40° C. and −15° C. and a shear modulus G* measured at 60° C. of between 0.5 MPa and 1.1 MPa.

    摘要： An aerodynamically optimized drag-reduction apparatus for optimally reducing the drag-induced resistive forces upon a terrestrial vehicle, where the drag-induced resistive moments on wheel surfaces pivoting about the stationary point of ground contact are reduced, and the vehicle propulsive forces needed to countervail the resistive forces on the wheel are reduced. The drag reduction apparatus includes: a streamlined fairing positioned on a vehicle to shield the faster moving upper wheel surfaces from headwinds; an engine exhaust pipe disposed on a vehicle whereby exhaust gases deflect headwinds to shield the faster moving upper wheel surfaces of an automotive wheel; an automotive spoked wheel having streamlined oval-shaped wheel spokes; a streamlined spoke tailfin rotatably attached to a wheel spoke; a cycle wheel with a tapered spoke having a thin aerodynamic profile near the rim and tapering to a round profile towards the central hub; and a tire having streamlined tread blocks arranged in an aerodynamic pattern.

    摘要： An aerodynamically optimized drag-reduction means and method for optimal minimization of the drag-induced resistive forces upon a terrestrial vehicle wheel, where the drag-induced resistive moments on wheel surfaces pivoting about the point of ground contact are reduced, and the vehicle propulsive forces needed to countervail the resistive forces on the wheel are reduced. The drag reduction means includes: a streamlined wheel cover positioned on a vehicle to shield the faster moving upper wheel surfaces from headwinds; a streamlined wind-deflecting fairing positioned on a vehicle to shield the faster moving upper wheel surfaces from headwinds; an engine exhaust pipe diposed on a vehicle whereby exhaust gases deflect headwinds to shield the faster moving upper wheel surfaces of an automotive wheel; an automotive spoked wheel having streamlined oval-shaped wheel spokes arranged in one or more rows for greater axial strength; a streamlined tailfin rotatably attached to a wheel spoke, which thereby may pivot about the spoke in response to varying crosswinds; and a tire having streamlined tread blocks arranged in an aerodynamic pattern.
