Publication number: 20240100885Abstract: 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.Type: ApplicationFiled: December 9, 2021Publication date: March 28, 2024Inventors: Jean-Luc GUERBERT-JUBERT, François BARBARIN, Olivier REIX, Philippe MANSUY, Lucas LAUBY, Sébastien NOEL
