Abstract: Improve endurance of tire for heavy-duty vehicle of construction plant type. A hoop reinforcement has an axially continuous first hooping layer and axially discontinuous second hooping layer, first layer has an axial width LF1 at least equal to 25% and at most 75% of axial width LT of working reinforcement, the discontinuous second hooping layer consists of two hooping strips symmetrical with respect to equatorial plane (XZ) of tire, each extends axially from axially interior end as far as axially exterior end over an axial width LF2 which is at least equal to 10% and at most 35% of axial width LF1 of the first hooping layer, and the distributed tension at break TR of each hooping strip defined as the product of number D of reinforcers per mm times the force at break FR of each reinforcer expressed in daN, is at least equal to 100 daN/mm.

Abstract: The invention relates to a tire for a heavy vehicle of construction plant type, comprising a working reinforcement (50), a protective reinforcement (60) and a hoop reinforcement (70). The working reinforcement (50) comprises two layers (51, 52) comprising inelastic metallic reinforcers that are crossed and make angles of between 30° and 35° with the circumferential direction, and having a force at break greater than 2500 daN. The hoop reinforcement (70) is formed by a circumferential winding forming two layers (71, 72), radially positioned between the working layers (51, 52), comprising circumferential elastic metallic reinforcers, having a force at break greater than 800 daN. The metallic reinforcers of the protective layers (61, 62) are potentially identical to the reinforcers of the hoop reinforcement, crossed from one layer to another with angles identical to the working layers. These reinforcers are elastic, have a diameter greater than 3 mm and a force at break greater than 800 daN.

Abstract: A hoop reinforcement is provided for a tire for a heavy vehicle of construction plant type. The crown reinforcement (3) of the tire (1), radially on the inside of a tread (2), comprises a protective reinforcement (6), a working reinforcement (5) and a hoop reinforcement (7). The hoop reinforcement (7) is formed by a circumferential winding, in the circumferential direction (XX?), of a ply of metallic reinforcers (8) forming an angle at most equal to 2.5° with the circumferential direction (XX?), extending from an initial radially inner end (81) to a final radially outer end (82), forming a spiral, such that the hoop reinforcement (7) comprises at least two hooping layers (71, 72) around the entire circumference and at least three hooping layers (71, 72, 73) over an angular sector A, delimited by the initial and final ends (81, 82), respectively, of the hoop reinforcement (7).

Abstract: The manufacturing cost of a hoop reinforcement of a tire for a heavy vehicle of construction plant type is reduced. The crown reinforcement (3) of the tire (1), radially on the inside of a tread (2), comprises a protective reinforcement (6), a working reinforcement (5) and a hoop reinforcement (7). The hoop reinforcement (7) is made up of at least two hooping layers (71, 72), each hooping layer (71, 72) comprising metallic reinforcers that are coated in an elastomeric coating material and form an angle at most equal to 2.5° with the circumferential direction (XX?). Each hooping layer (71, 72) is formed by a circumferential winding in a ring, in the circumferential direction (XX?), of at least one portion of a ply of metallic reinforcers (81, 82), extending from an initial end (811, 821) to a final end (812, 822), such that the hooping layer (71, 72) comprises at least one discontinuity (91, 92).
