Patent number: 8499808Abstract: A tire comprising a carcass-type reinforcement structure formed from reinforcing elements anchored on each side of the tire to a bead, the base of which is intended to be mounted on a rim seat, each bead being extended radially outwards by a sidewall, the sidewalls joining, radially outwards, a tread and having, beneath the tread, a crown reinforcement structure consisting of at least two layers of reinforcing elements called working layers, said reinforcing elements of the working layers being of identical nature. In a given circumferential plane, the extensional stiffness per unit width of a first working layer measured along the principal direction of the reinforcing elements of said first layer is strictly higher than the extensional stiffness per unit width of a second working layer measured along the principal direction of the reinforcing elements of said second working layer, the second working layer being radially further away from the carcass structure than said first working layer.Type: GrantFiled: February 20, 2007Date of Patent: August 6, 2013Assignee: Michelin Recherche et Technique S.A.Inventors: Francis Bordoz, Yannick Gerbal
