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.
