  • Patent number: 7918258
    Abstract: A tire for a two-wheeled motorized vehicle includes a carcass-type reinforcement structure, having reinforcement elements anchored on each side to a bead. Each bead extends radially by a sidewall, which meets up radially with a tread. Under the tread is a crown reinforcement structure including at least one working layer of working reinforcement elements, and a layer of circumferentially oriented reinforcement elements disposed radially to the outside of the carcass-type reinforcement structure. Over the profile of the tire in a radial plane, radially to the outside of the two points of tangency of the curvilinear abscissa of the carcass-type reinforcement structure with perpendiculars to the axis of rotation, at least one layer of working reinforcement elements is at least partially radially to the inside of the part of the carcass-type reinforcement structure radially to the outside of the two points of tangency.

  • Patent number: 7658216
    Abstract: A motorcycle tire includes at least one carcass-type reinforcement structure formed of reinforcement elements, anchored on either side of the tire to a bead whose base is intended to be mounted on a rim seat, each bead being extended radially towards the outside by a sidewall. The sidewalls meet up radially towards the outside with a tread. Under the tread there is a crown reinforcement structure including at least one layer of reinforcement elements known as a working layer which has at least one continuous reinforcement cord forming portions in the central zone thereof. Those central cord portions display identical angles of between 10-80 degrees formed with the longitudinal direction, the angles being measured at points of intersection of the cord with a circumferential plane. Two adjacent cord portions are linked by a U-shaped loop.

  • Publication number: 20090229718
    Abstract: A tire for a motorized two-wheeled vehicle and more particularly for a motorcycle. A tire such as this comprises at least one reinforcing structure of the carcass type, formed of reinforcing elements, anchored on each side of the tire into a bead the base of which is intended to be mounted on a rim seat, each bead extending radially outwards in the form of a sidewall, the sidewalls radially towards the outside meeting a tread, and comprising, under the tread, a crown reinforcing structure made up of at least one layer of reinforcing elements termed the working layer. At least locally, the tread comprises a first polymer compound and of at least one second polymer compound having physico-chemical properties different from those of the said first polymer compound, at least 75% of the volume of the tread consisting of the first polymer compound, and the second polymer compound being distributed discretely.
