Crown reinforcement for a tire for a heavy-duty civil engineering vehicle

A tire for a heavy construction-type vehicle, the tire comprising:

• a tread structured to come into contact with a ground surface;
• a radial carcass reinforcement positioned radially inside relative to the tread, the radial carcass reinforcement including at least one carcass layer;
• and
• a crown reinforcement positioned radially inside relative to the tread, and positioned radially outside relative to the radial carcass reinforcement, the crown reinforcement including a working reinforcement and a hoop reinforcement,
• wherein the working reinforcement includes a plurality of working layers, each of the working layers including inelastic metallic reinforcers that:
• (a) are crossed from one working layer to another working layer, and (b) make an angle in a range of from at least 28° to at most 33° with respect to a circumferential direction,
• wherein the hoop reinforcement is formed of a circumferentially wound ply that includes circumferential elastic metallic reinforcers, the circumferential elastic metallic reinforcers making an angle equal to at most 2.5° with respect to the circumferential direction, the circumferentially wound ply being wound from a first circumferential end to a second circumferential end, so that the second circumferential end is located radially outside relative to the first circumferential end, and so that the circumferentially wound ply forms a radial stack of at least two hooping layers,
• wherein the hoop reinforcement is radially positioned between two of the working layers, and
• wherein the circumferential elastic metallic reinforcers of the hoop reinforcement have a force at break equal to at least 800 daN,
• wherein the circumferential elastic metallic reinforcers of the hoop reinforcement have a modulus of elasticity at 10% elongation in a range of from at least 70 GPa to at most 110 GPa,
• wherein the first and second circumferential ends of the circumferentially wound ply of the hoop reinforcement make an angle in a range equal to at least 25° with respect to an axial direction, and
• wherein a circumferential distance between the first circumferential end and the second circumferential end of the circumferentially wound ply of the hoop reinforcement is in a range of from at least 0.6 m to at most 1.2 m.
