  • Publication number: 20130199691
    Abstract: The invention relates to a tire with a radial carcass reinforcement comprising a crown reinforcement, itself radially capped with a tread, the said tread being connected to two beads via two sidewalls. According to the invention, the crown reinforcement comprises at least one axially continuous layer consisting of at least two bands arranged in contact with one another in the axial direction and each formed of at least one multilayer laminate, the lateral edges of the said at least two bands being oriented substantially circumferentially, the width of the said at least one axially continuous layer being greater than half the width of the tread and each laminate comprising at least one multiaxially stretched thermoplastic polymer film positioned between and in contact with two layers of rubber composition.
