A radial tire is described, in particular for private passenger vehicles or pick-up trucks, having an improved belt structure comprising a multiply laminated composite (10) comprising at least three superposed reinforcement layers (110, 120, 130), each reinforcement being unidirectionally arranged in one of the layers and embedded in respective rubber thicknesses (C1, C2, C3), a first rubber layer (C1) comprising at least one row of circumferential heat-shrinkable textile reinforcements (110), made for example of nylon or polyester; this first layer radially covers (in the Z direction) two other layers (C2, C3) comprising metallic reinforcements (120, 130) which cross from one layer to the other in the form of steel monofilaments having a diameter from 0.20 mm to 0.50 mm; the reinforcements (110) made of heat-shrinkable textile material are ribbons having a thickness (T) from 0.1 to 1 mm and a width (W) from 2 to 50 mm.
