Tire comprising a layer of circumferential reinforcing elements

A tire with a radial carcass reinforcement, comprising:

• a crown reinforcement formed from at least two working crown layers of reinforcing elements, with one layer crossing the next at angles in the range from 10° to 45° with the circumferential direction, said at least two working crown layers each being formed of reinforcing elements inserted between two skim coats of rubber mixture, and including a layer of circumferential reinforcing elements,
• wherein the tensile modulus of elasticity at 10% elongation of at least one skim coat of at least one working crown layer is greater than 9 MPa,
• wherein the maximum value of tan δ denoted tan δ max, of said at least one skim coat of at least one working crown layer is less than 0.100,
• wherein said at least one skim coat of at least one working crown layer is an elastomeric mixture based on:
• natural rubber or synthetic polyisoprene with a majority of cis-1,4 chains, and optionally at least one other diene elastomer, the natural rubber or the synthetic polyisoprene in case of blending being present in a majority proportion relative to the proportion of the other diene elastomer or elastomers used, and
• a reinforcing filler composed of carbon black with a BET specific surface of less than or equal to 44 m2/g, regardless of its structural index, used in a proportion of 40 to 100 phr, and
• a tread radially capping the crown reinforcement and joined to two beads via two sidewalls.
