Abstract: The process for drawing a steel wire applies to a wire having a carbon content by weight C such that 0.4%?C?0.74%. The process comprises an uninterrupted series of drawing steps (7001-700m) of the wire from a diameter d? to a diameter d, d? and d being expressed in mm, in which the true strain ??=2.ln(d?/d) is such that ??>4.

Abstract: The steel wire of diameter d expressed in mm, has a carbon content by weight C, expressed in %, such that 0.4%?C?0.5% and a maximum tensile strength R, expressed in MPa, such that R?A.(920.C+500)/d1/2 with A=0.87.

Abstract: The steel wire of diameter d expressed in mm, has a carbon content by weight C, expressed in %, such that 0.5%?C?0.6% and a maximum tensile strength R, expressed in MPa, such that R?A·(920·C+500)/d1/2 with A=1 and R?2950 MPa.

Abstract: The steel wire of diameter d expressed in mm, has a carbon content by weight C, expressed in %, such that 0.6%?C?0.74% and a maximum tensile strength R, expressed in MPa, such that: for d<0.17, R?A.(920.C+500)/d1/2 with A=0.96, for 0.17?d?0.23, R?A.(920.C+500)/d1/2 with A=1.24.

Abstract: A radial tyre, which is useable for a passenger vehicle or a van, has a crown reinforcement or belt having a lightened belt structure. The lightened belt structure is constructed of a multilayer composite laminate that includes a first layer of rubber that radially surmounts, in a direction Z, two other layers of rubber. The first layer of rubber includes weakly heat-shrinkable textile circumferential reinforcers, for example, made of nylon or polyester. The two other layers of rubber are reinforced with monofilaments of high tensile steel. The multilayer composite laminate allows the tyre's weight and rolling resistance to be reduced without impairing the tyre's cornering stiffness and, therefore, road holding and handling. At the same time, the multilayer composite laminate enables the tyre to have a running endurance that is at least equivalent if not better than that of a conventional tyre.

Abstract: Radial tyre, notably, for a passenger vehicle or van, with a lightened belt structure (10) comprising a multilayer composite laminate (10a, 10b, 10c) of specific construction with a first layer (10a) of rubber (C1) comprising heat-shrinkable textile circumferential reinforcers (110) made of polyester, for example PET or PEN, 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 tyres to be reduced without impairing the cornering stiffness and, therefore, road holding and handling, while at the same time offering running endurance that is at least equivalent if not better.
