Abstract
A tire with a radial carcass reinforcement comprising a crown reinforcement formed from at least two working crown layers of inextensible reinforcing elements and from at least one layer of circumferential reinforcing elements positioned radially between two working crown layers, the working crown layers adjacent to the layer of circumferential reinforcing elements being on each side of the equatorial plane and in the axial continuation of the layer of circumferential reinforcing elements coupled over an axial width, in order thereafter to be decoupled. A layer of polymer blend having a thickness greater than 1.5 mm over an axial width greater than 0.1×d is positioned axially between the axially exterior end of the layer of circumferential reinforcing elements and the axially interior end of the coupling zone of the working crown layers.
