TIRE COMPRISING CARCASS REINFORCEMENT CABLES HAVING LOW PERVIOUSNESS, AND TEXTILE THREADS ASSOCIATED WITH THE CARCASS REINFORCEMENT

摘要

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, at least one layer of the carcass reinforcement is provided, on the surface of at least one calendering layer, with textile threads and the said at least one calendering layer of the said at least one carcass reinforcement layer is an elastomeric mixture based on natural rubber or on synthetic polyisoprene and on a reinforcing filler conferring high cohesion.
