TIRE COMPRISING CASING-REINFORCING CABLES HAVING LOW PERMEABILITY, AND FABRIC THREADS COMBINED WITH THE CASING REINFORCEMENT

摘要

The invention relates to a tire having a radial casing reinforcement consisting of at least one layer of metal reinforcement elements, said tire including a crown reinforcement, which is in turn radially covered by a tread that is joined to two beads via two sidewalls. According to the invention, the metal reinforcement elements of at least one layer of the casing reinforcement are cables having a flow rate of less than 20 cm3/min in the so-called permeability test, at least one layer of the casing reinforcement is provided on at least one surface consisting of fabric threads, and at least the elastomeric mixture layer, which is arranged radially outside the bead wire and which engages with the latter, consists of an elastomeric mixture containing natural or isoprene rubber and a reinforcing filler imparting high cohesion thereto.
