Claim:
A heavy-load vehicle tire configured to be operable on a heavy-load vehicle and having a radial carcass reinforcement comprising: a crown reinforcement formed of at least two working crown layers of inextensible reinforcement elements, which are crossed from one ply to the other, forming angles of between 10° and 45° with a circumferential direction of the tire, and topped radially by a tread, said tread being joined to two beads by means of two sidewalk; and in each shoulder, at least one additional layer of reinforcement elements which are oriented circumferentially and have an undulation; wherein an axially inner end of said additional layer is radially adjacent to an edge of one of the working crown layers; wherein at least part of said additional layer is at least one of radially and axially coupled to an edge of an axially widest working crown layer; wherein a layer P of cohesive rubber mixes is arranged between at least part of the working crown layers; wherein an axially outer end of the layer P is axially between ends of axially least wide and widest working crown layers; wherein a ratio of an elasticity modulus of the layer P to an elasticity modulus of a calendering layer of a working crown layer adjacent to the additional layer is of between 0.5 and 1; wherein the crown reinforcement comprises at least one continuous layer of circumferential reinforcement elements; and wherein the at least one continuous layer of circumferential reinforcement elements is arranged radially between two working crown layers.
