Abstract: A radial tire (1) for a heavy-duty vehicle, in which the reinforcing elements of each hooping layer (331, 332, 333), forming an angle at most equal to 5° with the circumferential direction, and the reinforcing elements of the transverse reinforcer layers (321, 322, 323), forming an angle of between 10° and 45° with the circumferential direction, are extensible and therefore such that, in their rubberized state extracted from a polymer matrix, their structural elongation As is at least equal to 0.5%, their total elongation at break At is at least equal to 3% and their tensile Young's modulus E is at most equal to 150 GPa.

Abstract: A radial tire (1) for a heavy-duty vehicle, with at least two working layers (321, 322, 323, 324) in which the reinforcing elements form an angle at least equal to 10° and at most equal to 45° with the circumferential direction. The metal reinforcers of all of the crown layers of the crown reinforcement are extensible and therefore have, in their rubberized state extracted from a polymer matrix, a structural elongation As at least equal to 0.5%, a total elongation at break At at least equal to 3% and a tensile Young's modulus E at most equal to 150 GPa. The narrower of the two working layers has an axial width at least equal to 60% of the width of the tread and the wider of the two working layers has an axial width at least equal to 70% of the width of the tread.

Abstract: A tire having a radial carcass reinforcement, made up of a single layer of reinforcing elements anchored in each of the beads by being turned up around a bead wire, reinforced by a stiffener.

Abstract: The reinforcing structure for a tire is in the form of a stratified assembly formed of two layers of reinforcing strips of completely connected cross section, and flattened in shape. According to the method, the strips of each layer are laid side by side in a main direction of laying. The strips of the first layer are spaced apart by a distance that is less than the width of the strips of the second layer and in such a way that the edges of the strips of the first layer overlap the edges of the strips of the second layer. The two layers of strips are separated by a layer of uncoupling rubber.

Abstract: A tire comprising a crown, two sidewalls and two beads, a casing reinforcement anchored in each of the beads and a crown reinforcement, the crown reinforcement comprising radially, from the inside outwards, a working block and a protective block having at least one ply of circumferentially oriented parallel reinforcing threads, characterized in that the protective block ply consists of aromatic polyamide reinforcing threads with an initial modulus of less than 1000 cN/tex and a tenacity of greater than 65 cN/tex.
