A radial tire, notably for a passenger vehicle or van, with a lightened belt structure (10) comprises a multilayer composite laminate (10a, 10b, 10c) of specific construction, with a first layer (10a) of rubber (C1) reinforced with preferably weakly heat-shrinkable circumferential textile multifilament fibres (110) twisted individually on themselves, for example, made of nylon or of polyester, 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 tires to be reduced without impairing the cornering stiffness and, therefore, road holding and handling, while at the same time offering equivalent running endurance. |
