  • Patent number: 5922154
    Abstract: A pneumatic vehicle tire includes a carcass, a tread strip, a breaker arrangement provided between the carcass and the tread strip and includes at least two breaker plies having threads or cords of non-metallic material which extend at a predetermined angle to the mid-circumferential plane of the tire and serve as reinforcing elements. A breaker cover surrounds the breaker arrangement, or at least in, regions of its width. The breaker cover includes at least one cover ply having threads or cords which extend at least substantially in the circumferential direction of the tire. The breaker cover has threads or cords of a heat-shrinking material substantially in the shoulder region of the tire. In the middle tire region lying between the threads or cords either no breaker cover is provided or a breaker cover is provided with threads or cords of a material with low thermal shrinkage or no thermal shrinkage.

  • Patent number: 5795417
    Abstract: A pneumatic vehicle tire comprises a single ply or multi-ply radial carcass anchored to beads, a tread, and a breaker arrangement provided between the carcass and the tread. The breaker arrangement is preferably built up of at least two cut breaker plies with the threads or cords of the cut breaker plies, which serve as strength carriers and extend parallel to one another in the respective ply, crossing at a predetermined angle to the central mid-circumferential plane. The tire also comprises at least one cover ply of cords or threads extending substantially in the circumferential direction of the tire, at least one cover ply surrounding the breaker arrangement at least in the breaker arrangement's edge regions. In the preferred embodiment the breaker arrangement (4) has threads or cords (9) of non-metallic material and a material with a low thermal shrinkage or no thermal shrinkage is used as the material for the treads or cords (8) of the at least one cover ply (5).
