  "textContent": "A tire for a heavy-duty vehicle of construction plant type comprises a crown reinforcement () radially on the inside of a tread () and radially on the outside of a carcass reinforcement (). The crown reinforcement () comprises: at least one “low-modulus” layer () formed of elastic metal reinforcers having a structural elongation at least equal to 0.4%, and a total elongation at break at least equal to 3%, and a tensile elastic modulus of between 40 GPa and 130 GPa; at least one “rigid” layer (30) formed of rigid metal reinforcers, the structural elongation of which is less than or equal to 0.2% and the tensile elastic modulus of which is between 140 GPa and 200 GPa. The ratio of the breaking tension of the rigid layer to that of the low-modulus layer is greater than or equal to 1.2.",
