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, at least two rubber blend layers Ci being disposed between the ends of the working layers. According to the invention, the thickness of the working layers, measured in the equatorial plane, is less than 5 mm, the reinforcing elements thereof being 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 working layers is greater than 60 % of the axial width of the tread; the tensile modulus of elasticity at 10% elongation of at least one layer Ci is less than 8 MPa; and the maximum tan(δ) value is less than 0.100.
