Patent ID: 8448682

Claim:
A tire with a radial carcass reinforcement comprising a crown reinforcement formed of at least two working crown layers of inextensible reinforcing elements, crossed from one layer to the other making angles of between 10° and 45° with the circumferential direction, itself radially topped by a tread, the said tread being joined to two beads by means of two sidewalls, the crown reinforcement comprising at least one layer of circumferential reinforcing elements positioned radially between two working crown layers, wherein at least one layer of circumferential reinforcing elements has an axial width greater than 0.5×S, wherein it is made up of two parts separated axially from one another, and wherein, axially between the two parts of the layer of circumferential reinforcing elements, two working crown layers are coupled over an axial width greater than 0.035×S, wherein at least one layer of polymer blend of an axial width less than the axial distance separating the two parts of the layer of circumferential reinforcing elements is present radially on the outside of the working layer radially adjacent and exterior to the layer of circumferential reinforcing elements, wherein the at least one layer of polymer blend is interposed between the two parts of the layer of circumferential reinforcing elements, and wherein the at least one layer of polymer blend is radially covered by an additional layer comprising reinforcement elements.
