Abstract: Tire for heavy off-the-road vehicles including a radial carcass reinforcement anchored in each bead to an annular bead reinforcement element, and radially above it a crown reinforcement consisting of at least two working crown plies of inextensible metallic cables crossed from one ply to the next, the said plies having widths at least equal to 50% of the width L of the tread and, radially above these, two protection crown plies of so-termed elastic metallic cables crossed from one ply to the next, the tread including in its ungrooved portion of thickness D at least one armature of reinforcement elements, wherein the said armature is composed of at least two layers of textile monofilaments parallel to one another in each layer, the axial widths of the said two layers being at least equal to the width of the narrower working ply.

Abstract: Tire for heavy off-the-road vehicles comprising a radial carcass reinforcement (1) anchored in each bead to an annular bead reinforcement element (2), and radially above it a crown reinforcement (3) consisting of at least two working crown plies (320, 321) of inextensible metallic cables crossed from one ply (320) to the next (321), the said plies having widths at least equal to 50% of the width L of the tread (4) and, radially above these, two protection crown plies (330, 331) of so-termed elastic metallic cables crossed from one ply (330) to the next (331), the tread (4) comprising in its ungrooved portion of thickness D at least one armature (34) of reinforcement elements, wherein the said armature (34) is composed of at least two layers (340, 341) of textile monofilaments parallel to one another in each layer, the axial widths of the said two layers (340, 341) being at least equal to the width of the narrower working ply (321).

Abstract: Reinforcement ply N for a tire, formed of reinforcement elements embedded in coating products, characterized in that it comprises a first C1 and a second C2 layer of metallic elements E1, E2 parallel to one another, embedded in a coating product or coating products M1, M2 and, between the said two layers C1 and C2, a third layer C3 of elements E3 made from a textile material and embedded in a coating product M3, the said textile elements E3 being orientated relative to the elements E1 and E2 at an angle between 70° and 110°.
