Tire comprising a layer of circumferential reinforcing elements

A tire comprising:

• a radial carcass reinforcement comprising a crown reinforcement comprising;
• at least two working crown layers of reinforcing elements crossed from one layer to the other while forming, with a circumferential direction, angles of between 10° and 45° , wherein the at least two working crown layers have unequal axial widths,
• a layer C of rubber mixture being positioned between at least the ends of the at least two working crown layers,
• at least one layer of circumferential reinforcing elements positioned radially between two working crown layers, wherein the distance d between the end of the axially narrowest working layer and the working layer separated from the axially narrowest working layer by the layer C of rubber mixture is such that 1.1ø<d<2.2ø, ø being the diameter of the reinforcing elements of the at least one layer of circumferential reinforcing elements, and wherein, in a meridian plane, the thickness of the layer C of rubber mixture does not vary by more than 0.3 mm over the axial width between the axially interior end of the layer C and the end of the axially narrowest working layer,
• wherein the axial widths of the working crown layers radially adjacent to the layer of circumferential reinforcing elements are greater than the axial width of the layer of circumferential reinforcing elements, and
• wherein the working crown layers adjacent to the layer of circumferential reinforcing elements on either side of an equatorial plane and, in an immediate axial extension of the layer of circumferential reinforcing elements, coupled over an axial width, in order to be subsequently decoupled by said layer C of rubber mixture of at least over the remainder of the width common to the two working layers,
• a tread, the tread being joined to two beads via two sidewalls, and
• wherein the tread radially tops the crown reinforcement.
