Abstract

992,341. Pneumatic tyres. PNEUMATIQUES CAOUTCHOUC MANUFACTURE ET PLASTIQUES KLEBER COLOMBES. March 14, 1962 [March 15, 1961], No. 9798/62. Heading B7C. A pneumatic tyre has a carcase of two layers or two sets of layers A, B of parallel radial cords, the cords of the inner layer or set A being more extensible than the cords of the outer layer or set B at least in the lower sidewall region adjacent the bead cores 2 to provide better flexibility in that region. As shown, the inner layer A is turned outwardly around the bead core 2, and the outer layer B is turned inwardly therearound. The greater extensibility of the cords of the inner layer A may be achieved by forming corrugated pleats therein, as shown, adjacent the bead core 2, the cords of both layers being of metal, or natural or synthetic textile material. Alternatively the cords of the inner layer may be of a more extensible material, such as nylon, compared with the cords of the outer layer which may be of rayon.
