| 摘要 |
The invention relates to a tyre comprising a crown reinforcement formed of at least two working crown layers of reinforcing elements, a first layer C of rubber compound being positioned between at least the ends of said at least two working crown layers, a second 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 the first layer C is less than 8 MPa, the maximum value of tan(δ), denoted tan(δ)max, of the first layer C is less than 0.100, and the complex dynamic shear modulus G*, measured at 10% and 60°C on the return cycle, of said second layer S of polymer compound is greater than 1.35 MPa. |
