  • Patent number: 9108465
    Abstract: A tire having a radial carcass reinforcement, comprised of at least one layer of metal reinforcing elements, said tire comprising a crown reinforcement, which is itself covered radially with a tread, said tread being joined to two beads via two sidewalls. The metal reinforcing elements of at least one layer of the carcass reinforcement are non-hooped cords having, in the permeability test, a flow rate of less than 20 cm3/min and at least one layer of the carcass reinforcement being provided on at least one side with textile threads oriented mainly along a direction parallel to that of the metal reinforcing elements of said at least one carcass reinforcement layer, said textile threads being corrugated about this main direction.

  • Patent number: 8695667
    Abstract: Method of manufacturing a tire comprising a carcass reinforcement extending between beads, this carcass reinforcement being anchored in each bead by being wrapped around each circumferential bead reinforcement to form a turned-back portion, this carcass reinforcement comprising at least one rubber ply which is reinforced with a plurality of metal cords of low or zero permeability, each bead comprising a plurality of rubber-based strips, at least one of these strips, known as the bead rubber strip, radially on the outside of the circumferential bead reinforcement performing a function of filling and mechanical connection between the carcass reinforcement and its turned-back portion, this bead rubber strip comprising a first surface axially towards the inside in contact with the carcass reinforcement and a second surface axially towards the outside, each bead further comprising at least one other strip, known as the filler strip which, radially on the outside of the radially outermost points of the turned-back
