    摘要: The invention relates to a tyre with a radial carcass reinforcement made up of at least one layer of reinforcing elements which is anchored in each of the beads by being wrapped around a bead wire, said wrapped-around portion of carcass reinforcement being reinforced by at least one layer of reinforcing or stiffening elements the radially outer end of which is radially on the outside of the end of the wrapped-around portion. According to the invention, the reinforcing elements of at least one stiffener are unwrapped metal cords with saturated layers which on the test known as the permeability test return a flowrate of less than 5 cm
    3 /min, the radially inner end of said stiffener being radially on the inside of that point of the bead wire that is radially closest to the axis of rotation, and the elastic modulus of the polymer compounds in the calendered layers of the carcass reinforcement is less than or equal to 8 MPa.

    摘要: The tyre (10) for a vehicle of construction type comprises a tread (22) and a crown reinforcement (14) arranged radially on the inside of the tread (22). The crown reinforcement (14) comprises: a protective reinforcement (36) comprising at least one protective ply (42, 44) having a breaking strength Fm
    NSP ; a working reinforcement (38) comprising at least one working ply (46, 48) having a breaking strength F
    MNST ; and a hoop reinforcement (39) comprising at least one hooping ply (40, 41), the hooping ply (40, 41) comprising reinforcing elements referred to as hoop reinforcements, the hoop reinforcing elements making an angle at most equal to 10° with the circumferential direction of the tyre (10); the working reinforcement (38) is arranged radially on the inside of the protective reinforcement (36); the ratio Fm
    NSP /Fm
    NSr is greater than or equal to 0.27 and less than or equal to 0.90.
