TYRE COMPRISING A LAYER OF CIRCUMFERENTIAL REINFORCING ELEMENTS

摘要

The invention relates to a tyre comprising a crown reinforcement formed of at least two working crown layers each formed of reinforcing elements inserted between two calendering 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 reinforcement comprising at least one layer of circumferential reinforcing elements. According to the invention, the elastic modulus under 10% tensile strain of at least one calendering layer of at least one working crown layer is less than 8.5 MPa and the maximum value of tan(delta), denoted tan(delta) max, of said at least one calendering layer of at least one working crown layer is less than 0.100.
