Patent ID: 8678056

Claim:
A tire with a radial carcass reinforcement comprising: a crown reinforcement formed of at least two working crown layers of inextensible reinforcing elements, said two working crown layers are crossed from one layer to the other layer making angles of between 10° and 45° with the circumferential direction, said crown reinforcement radially capped by a tread, said tread being connected to two beads via two sidewalls, said crown reinforcement comprising at least one layer of circumferential reinforcing elements positioned radially between said two working crown layers, said two working crown layers are adjacent to said at least one layer of circumferential reinforcing elements being on each side of the equatorial plane, in an axial continuation of said layer of circumferential reinforcing elements, and coupled in a coupling zone having an axial width 1 , in order thereafter to be decoupled by profiled elements of rubber compound at least over a remainder of a width common to said two working crown layers, wherein a layer of polymer blend having a thickness greater than 1.5 mm over an axial width greater than 0.1 times a distance (d) is positioned axially between an axially exterior end of said layer of circumferential reinforcing elements and an axially interior end of said coupling zone of the working crown layers adjacent to said layer of circumferential reinforcing elements, and wherein said distance (d) is an axial distance separating an end of the narrowest working crown layer adjacent to said layer of circumferential reinforcing elements from the nearby axially exterior end of said layer of circumferential reinforcing elements.
