  • Patent number: 9168790
    Abstract: A motorized two-wheeled vehicle, comprising a radial carcass reinforcement formed of at least two layers of reinforcing elements, and comprising underneath the tread a crown reinforcement structure comprising of at least one layer of reinforcing elements. At least the tread surface comprises a first polymeric compound extending in at least the region of the equatorial plane and at least one second polymeric compound having physicochemical properties different from those of said first polymeric compound, the density of reinforcing elements in the radially inner carcass reinforcement layer being less than that in the radially outer carcass reinforcement layer.
    Type: Grant

  • Patent number: 8776848
    Abstract: A tire for a motorized two-wheeled vehicle, comprising a carcass-type reinforcing structure formed of at least two layers of reinforcing elements, and comprising underneath the tread a crown reinforcement structure comprising at least one layer of reinforcing elements. At least the tread surface comprises a first polymeric compound extending in at least the region of the equatorial plane and at least one second polymeric compound having physicochemical properties different from those of said first polymeric compound, the reinforcing elements of said two or more layers forming the carcass-type reinforcing structure forming angles with the circumferential direction of between 70° and 85° and the distance between the reinforcing elements of each of said two or more layers forming the carcass-type reinforcing structure being not more than 0.5 mm across at least 60% of the axial width of at least one region composed of the second polymeric compound.
    Type: Grant

  • Patent number: 6945294
    Abstract: Tire for heavy off-the-road vehicles including a radial carcass reinforcement anchored in each bead to an annular bead reinforcement element, and radially above it a crown reinforcement consisting of at least two working crown plies of inextensible metallic cables crossed from one ply to the next, the said plies having widths at least equal to 50% of the width L of the tread and, radially above these, two protection crown plies of so-termed elastic metallic cables crossed from one ply to the next, the tread including in its ungrooved portion of thickness D at least one armature of reinforcement elements, wherein the said armature is composed of at least two layers of textile monofilaments parallel to one another in each layer, the axial widths of the said two layers being at least equal to the width of the narrower working ply.
