  • Annular reinforcing element for a tyre and tyre including the annular reinforcing element
    Patent number: 7661453
    Abstract: A tire for a vehicle wheel includes a carcass structure, a tread band extending circumferentially around the carcass structure, a belt structure circumferentially located between the carcass structure and the tread band, and at least one pair of sidewalls applied to the carcass structure in axially opposite positions. The carcass structure includes at least one carcass ply. Ends of the carcass structure are fastened to a pair of annular reinforcing elements, wherein each annular reinforcing element is incorporated in a respective bead of the tire includes at least one cord. The at least one cord includes at least one preformed metallic thread element.

  • Self-supporting tire for a vehicle wheel and method for manufacturing the tire
    Patent number: 6814119
    Abstract: A self-supporting tire for vehicle wheels includes a carcass structure having at least one carcass ply, a belt structure, a tread band, at least one pair of sidewalls, and at least one pair of resilient stiffening inserts incorporated into the carcass structure. The at least one carcass ply includes axially-inner strip lengths and axially-outer strip lengths, and may also include axially-intermediate strip lengths. Each of the strip lengths extend in a U-shaped configuration around a cross-section outline of the carcass structure to define two side portions spaced apart from each other in an axial direction and a crown portion extending at a radially-outer position between the side portions. The resilient stiffening inserts are axially interposed between the side portions of the axially-inner strip lengths and the side portions of the axially-outer strip lengths.
