  • Publication number: 20140338811
    Abstract: A tire having a radial carcass reinforcement, composed of at least one layer of metal reinforcing elements, the said tire comprising a crown reinforcement, itself topped radially by a tread, the said tread being joined to two beads via two sidewalls. The metal reinforcing elements of at least one layer of the carcass reinforcement are cords exhibiting, in the “permeability” test, a flow rate of less than 20 cm3/min and at least one layer of the carcass reinforcement is provided, on at least one face, with textile threads and at least the layer of elastomeric mixture, radially external to the bead wire and in contact with the latter, is an elastomeric mixture based on natural rubber or on synthetic polyisoprene and on a reinforcing filler conferring high cohesion.

  • Publication number: 20130030097
    Abstract: This invention relates to an article, in particular a pneumatic tire for a vehicle, comprising at least one external rubber mixture, in particular a tread, said external mixture comprising a rubber mixture consisting of at least one diene elastomer such as BR, SBR or NR, a reinforcing filler such as silica, a crosslinking system such as a vulcanization system, between 0.2 and 10 pce of an antioxidant, for example a substituted paraphenylenediamine, and between 0.2 and 10 pce of a lanthanide acetylacetonate such as a neodymium actylacetonate. The latter makes it possible to advantageously reduce the consumption of antioxidant during the thermal oxidizing aging of the composition and hence of the external mixture.
