| 摘要 |
The invention relates to a tyre comprising a crown reinforcement formed of at least two working crown layers, each one formed of reinforcing elements inserted between two calendering layers or skims of rubber compound, a first layer S of polymer compound being in contact with at least one working crown layer and in contact with the carcass reinforcement and the crown reinforcement comprising at least one layer of circumferential reinforcing elements. According to the invention, the elastic modulus under tension at 10% elongation of at least one skim of at least one working crown layer is less than 8.5 MPa, the maximum value of tan (δ), denoted tan (δ)max, of said at least one skim of at least one working crown layer is less than 0.100 and the complex dynamic shear modulus G*, measured at 10% and 60°C on the return cycle, of said first layer S of polymer compound is greater than 1.35 MPa. |
