Abstract
A tire comprising a crown reinforcement formed from at least two working crown layers 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 first additional layer of polymer blend having a width at least equal to the widthof the coupling zone and having a maximum thickness of less than two times the thickness of the layer of circumferential reinforcing elements is positioned radially under the working crown layer radially adjacent to and inside the layer of circumferential reinforcing elements and is at least partially radially superposed on the coupling zone of the working crown layers.
