In order to desensitise the crown of a tyre for a heavy civil engineering vehicle in terms of impacts essentially hitting the centre of the tread, a tyre (1) is provided, comprising a tread (2), a bracing ply (3) and a casing ply (4), the bracing ply (3) comprising, radially from the outside towards the inside, a protective ply (5) comprising at least one layer (51, 52) consisting of elastic metal reinforcements, at an angle of >= 10 degrees to the circumferential direction, a working ply (6) comprising at least two layers (61, 62) consisting of non-elastic metal reinforcements crossed from one working layer to the next, at an angle of <= 60 degrees to the circumferential direction, and an additional ply (7) centered on the equatorial plane of the tyre, comprising at least one additional layer (71, 72) consisting of elastic metal reinforcements that, when extended, have a maximum elastic modulus of 150 GPa, at an angle of <= 10 degrees to the circumferential direction.
