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, preferably in the form of monofilaments or assemblies of monofilaments; 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.
