TYRE COMPRISING WORKING LAYERS FORMED BY INDIVIDUAL WIRES

摘要

The invention relates to a tyre comprising a crown ply formed by at least three working crown layers of reinforcing elements. According to the invention, in a meridian plane, the thickness of the layers, measured in the equatorial plane, is less than 5 mm; the reinforcing elements are individual metal wires having a diameter of less than 0.50 mm; the distance between the reinforcing elements, measured along the normal to the direction of the centre line of the wire, is strictly less than 1 mm; the axial width of each of the layers is greater than 60% of the axial width of the tread; the tensile modulus of elasticity at 10% elongation of at least one skim coat of at least one working crown layer is less than 8.5 MPa; and the maximum tan(δ) value, denoted tan(δ)max, of the skim coat is less than 0.100.
