Abstract

1,217,475. Pneumatic tyres. CONTINENTAL GUMMI-WERKE A.G. 17 Jan., 1969 [22 March, 1968], No. 2946/69. Heading B7C. A pneumatic tyre has a folded tread-reinforcing belt 7 comprising parallel cords 9 and rubber layers 12, with the folds 11 extending in the circumferential direction of the tyre, and with an additional rubber layer 13 of a maximum thickness of 2-5 times the cord diameter disposed in each of the folds 11. The cords of the belt 8 are disposed at between 10 and 30 degrees to the mid-circumferential plane. The rubber of layers 12 and 13 is of a hardness of 65‹ to 85‹ Shore A. In one arrangement, the layers 13 are each of asymmetrically pear-shaped cross-section and in a second arrangement the layers are each of symmetrical pear-shaped cross-section.
