TIRE COMPRISING A LAYER OF CIRCUMFERENTIAL REINFORCING ELEMENTS |
| 摘要 |
A tire comprising a crown reinforcement formed from at least two working crown layers of reinforcing elements, a layer C of rubber mixture being placed between at least the ends of said at least two working crown layers, the crown reinforcement including at least one layer of circumferential reinforcing elements wherein the tensile modulus of elasticity at 10% elongation of the layer C is greater than 9 MPa and the maximum value of tan(δ), denoted tan(δ)max, of the layer C is less than 0.100. |

1. A tire with a radial carcass reinforcement, comprising:
a crown reinforcement formed from:
at least two working crown layers of reinforcing elements, with one layer crossing the next at angles in the range from 10° to 45° with the circumferential direction,a layer C of rubber mixture placed between at least the ends of said at least two working crown layers,at least one layer of circumferential reinforcing elements, wherein the tensile modulus of elasticity at 10% elongation of the layer C is greater than 9 MPa and wherein the maximum value of tan(δ), denoted tan(δ)max, of the layer C is less than 0.100; and a tread radially capping the crown reinforcement and joined to two beads via two sidewalls. |
