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.
