Hooping reinforcement for a tire of a heavy duty civil engineering vehicle

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

• a crown reinforcement radially on the inside of a tread and radially on the outside of a carcass reinforcement, the crown reinforcement comprising a protective reinforcement, a working reinforcement, and a hoop reinforcement,
• the protective reinforcement, which is radially outermost in the crown reinforcement, comprising at least one protective layer, the protective layer comprising metallic reinforcers that form an angle at least equal to 10° with a circumferential direction XX′ tangential to the circumference of the tire,
• the working reinforcement comprising at least two working layers, each working layer comprising metallic reinforcers that form an angle at least equal to 15° and at most equal to 45° with the circumferential direction XX′ and are crossed from one working layer to the next, and
• the hoop reinforcement being formed by a circumferential winding, in the circumferential direction XX′, of a ply of metallic reinforcers extending from an initial radially inner end to a final radially outer end, forming a spiral, such that the hoop reinforcement comprises at least two hooping layers around the entire circumference and at least three hooping layers over an angular sector A, delimited by the initial and final ends, respectively, of the hoop reinforcement, the metallic reinforcers of the hoop reinforcement forming an angle at most equal to 2.5° with the circumferential direction XX′,
• wherein the hoop reinforcement comprises at least one discontinuity positioned circumferentially between the initial end and the final end, respectively, and any discontinuity is positioned circumferentially, with respect to the initial end or the final end, forming an angle at least equal to 90°.
