Radial tyre for civil engineering comprising two working layers (51, 52) and two hooping layers (41, 42) of which the extensible metal reinforcing elements form, with the circumferential direction (XX'), angles at least equal to 5° and at most equal to 16°, in terms of absolute values, each metal reinforcing element of each hooping layer (41, 42) being extensible, and having a structural elongation at most equal to 1% and at least equal to 0.3%, and the tangent linear stiffnesses of the reinforcing elements of each hooping layer at 1.5% of deformation being at least equal to 75 kN/mm and at most equal to 160 kN/mm, the axial width of the hooping layer LF also being scaled down according to the pitch and linear stiffness of the working layers.
