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

摘要

The invention relates to a tire having a radial carcass reinforcement that consists of at least one layer of metal reinforcement layers, said tire including at least one crown reinforcement, which is in turn radially covered by a tread, said tread being joined to two beads via two sidewalls. According to the invention, the metal reinforcement elements of at least one layer of the carcass reinforcement are cables having, in the so-called perviousness test, a flow rate of less than 20 cm³/min, and at least one carcass reinforcement layer is provided on at least one surface consisting of textile threads, and at least the layer made of an elastomeric mixture, which axially engages with the end of at least the radially innermost crown reinforcement layer and with the carcass reinforcement, is an elastomeric mixture containing natural rubber or synthetic polyisoprene and a reinforcing filler imparting high cohesion thereto.
