摘要： A passenger vehicle tire having hooping layer (71) that has a force at break FR per mm of axial width of the hooping layer at least equal to 35 daN/mm and has a secant extension modulus MA at least equal to 250 daN/mm, for an applied force F equal to 15% of FR. Working reinforcement (6) comprises a single working layer (61) the working reinforcers of which form, with the circumferential direction (YY′), an angle AT at least equal to 30° and at most equal to 50°. The carcass reinforcers of the at least one carcass layer (81) form, with the circumferential direction (YY′) and in the equatorial plane (XZ), an angle AC2 at least equal to 55° and at most equal to 80° and having an orientation opposite of that of angle AT of the working reinforcers so that the carcass reinforcers and the working reinforcers constitute a triangulation.

摘要： Tire (1) for a vehicle, comprising a radially outermost working layer (41) which comprises at least one undulation (412) in line with a rib (26). The undulation (412) is such that it is radially on the outside of the points of the working layer (41) that are in line with the centre of the bottom face (243) of the circumferential groove (25) closest to the undulation (412) and that the minimum radial distance (do), between the radially outer surface of the radially outermost working layer (41) and the tread surface (21) is at least 1 mm less than the radial distance (dc) between the radially outer surface (ROS) of the radially outermost working layer (41) and the tread surface (21), which is the distance in line with the circumferential groove (25) closest to the undulation (412) concerned.

摘要： A tire 2 includes: a tread 4 forming a tread surface 20; a band 14 disposed inward of the tread 4 in a radial direction; and a belt 12 disposed between the tread 4 and the band 14 in the radial direction. The tread 4 includes a center region 22 disposed at a center in an axial direction, and a shoulder region 24 disposed on an outer side in the axial direction. The band 14 includes a band cord. The band cord is helically wound and extends in a circumferential direction. The belt 12 includes a belt cord. The belt cord extends so as to be tilted relative to an equator plane. An absolute value of an angle of the belt cord relative to the equator plane is not less than 70° and not greater than 90°.

摘要： A tire having a radial carcass reinforcement, composed of at least one layer of metal reinforcing elements, the said tire comprising a crown reinforcement, itself topped radially by a tread, the said tread being joined to two beads via two sidewalls. The metal reinforcing elements of at least one layer of the carcass reinforcement are cords exhibiting, in the “permeability” test, a flow rate of less than 20 cm3/min and at least one layer of the carcass reinforcement is provided, on at least one face, with textile threads exhibiting, in the “permeability” test, a flow rate of between 1 and 3 cm3/min.

摘要： 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.

摘要： 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.
