Abstract

A conventional tyre carcass with a radial reinforcement inlay (15, 16) in the crown area of the radial tyre is provided with an additional reinforcement material layer (20, 21) comprising a flexible sheet-like structure with quadratic or rhombic bonding without a calendered-on rubber coating. This sheet-like structure can be subjected to pretreatment with a resorcinol/formaldehyde solution in order to ensure adhesion to the tyre rubber. Alternatively, an adhesive can be used for this purpose. The sheet-like structure can either be in the form of a prefabricated, cap-shaped overlay and can extend over the entire belt reinforcement, or can be applied as separate strips over the side edges of the belt reinforcement. The sheet-like structure, which has higher elasticity than the belt cord, enables the design of an appropriately reinforced, flexible transition region between the belt reinforcement inlay and the flexible regions at the sides of the tyre.
