A hooping reinforcement of a tire for a heavy duty civil engineering type vehicle is disclosed. 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 hooping reinforcement (7). Said hooping reinforcement (7) has an axial width at most equal to the smallest axial width (L61, L62) of the two working layers (61, 62), and comprises at least two hooping layers (71, 72) that are formed from strips each made up of elastic metal reinforcers. Each hooping layer (71, 72) is made up of an axial juxtaposition of contiguous turns of the strip (8), which are circumferentially wound around the working layer (51). Each strip (8) is at least 35 mm and at most 250 mm thick, and its distributed breaking tension is at least equal to 100 daN/mm.
