A radial tyre, which is useable for a passenger vehicle or a van, has a crown reinforcement or belt having a lightened belt structure. The lightened belt structure is constructed of a multilayer composite laminate that includes a first layer of rubber that radially surmounts, in a direction Z, two other layers of rubber. The first layer of rubber includes weakly heat-shrinkable textile circumferential reinforcers, for example, made of nylon or polyester. The two other layers of rubber are reinforced with monofilaments of high tensile steel. The multilayer composite laminate allows the tyre's weight and rolling resistance to be reduced without impairing the tyre's cornering stiffness and, therefore, road holding and handling. At the same time, the multilayer composite laminate enables the tyre to have a running endurance that is at least equivalent if not better than that of a conventional tyre. |
