Radial tyre, notably, for a passenger vehicle or van, with a lightened belt structure (10) comprising a multilayer composite laminate (10a, 10b, 10c) of specific construction with a first layer (10a) of rubber (C1) comprising heat-shrinkable textile circumferential reinforcers (110) made of polyester, for example PET or PEN, this first layer radially (in the direction Z) surmounting two other layers (10b, 10c) of rubber (C2, C3 respectively) reinforced with monofilaments (120, 130) of high tensile steel; this multilayer composite laminate allows the weight and rolling resistance of the tyres to be reduced without impairing the cornering stiffness and, therefore, road holding and handling, while at the same time offering running endurance that is at least equivalent if not better. |
