Abstract: 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.

Abstract: A radial tire, notably for a passenger vehicle or van, has a very thin belt structure comprising a multilayer composite laminate of specific construction, with a first layer of rubber reinforced by circumferential textile reinforcers in the form of monofilaments or assemblies of monofilaments, preferably slightly heat-shrinkable, for example made of nylon or of polyester, this first layer radially (in the direction Z) surmounting two other layers of rubber, reinforced by high-strength steel monofilaments. The mean thickness of rubber, measured in the radial direction (Z), separating a first reinforcer from the second reinforcer which is closest to it, and that separating a second reinforcer from the third reinforcer which is closest to it, are both less than or at most equal to 0.35 mm.

Abstract: A radial tire, notably for a passenger vehicle or van, has an improved belt structure comprising a multilayer composite laminate with a first layer of rubber comprising heat-shrinkable circumferential textile reinforcers, in the form of monofilament fibres twisted individually on themselves according to a twist greater than 100 turns per metre; this first layer radially (in the direction Z) surmounts two other layers of rubber, reinforced by reinforcers all or some of which are composite reinforcers made up of steel monofilaments sheathed with a thermoplastic material, the glass transition temperature of which is greater than 20° C. This laminate makes it possible to lighten the belts of tyres by reducing the thickness of the layers of rubber that make up part of their structure, and therefore to reduce the weight and rolling resistance of the tyres, without the risk of direct contact between the reinforcers.
