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.
