A tire for a heavy construction-type vehicle includes a tread, a radial carcass reinforcement, and a crown reinforcement. The crown reinforcement includes a working reinforcement and a hoop reinforcement. The working reinforcement includes two working layers, each of which includes inelastic metallic reinforcers that are crossed from one layer to a next layer and that make an angle in a range of from 15° to 40° with respect to a circumferential direction. The hoop reinforcement, which is a ply that is wound circumferentially to form a radial stack of at least two hooping layers, includes circumferential elastic metallic reinforcers that make an angle equal to at most 2.5° with respect to the circumferential direction. The hoop reinforcement is radially positioned between the working layers, and the circumferential metallic reinforcers of the hoop reinforcement have a force at break equal to at least 800 daN.
