TYRE COMPRISING A LAYER OF CIRCUMFERENTIAL REINFORCING ELEMENTS

摘要

A tire having a crown reinforcement formed of at least two working crown layers each formed of reinforcing elements inserted between two calendaring layers of rubber compound, crossed from one layer to the other making angles of between 10° and 45° with the circumferential direction and the crown reinforcements comprising at least one layer of circumferential reinforcing elements. The elastic modulus under 10% tensile strain of at least one calendaring layer of at least one working crown layer is less than 8.5 MPa and the maximum value of tan(δ), denoted tan(δ)max, of said at least one calendaring layer of at least one working crown layer is less than 0.100.
