20250153509. Pneumatic Tire Vehicle Reinforcing Structure Lower Toric Cavit (COMPAGNIE GENERALE DES ETABLISSEMENTS MICHELIN)

Pneumatic Tire for Vehicle with Reinforcing Structure in the Lower Toric Cavity

Abstract: a tire with improved handling having a stiffening structure with a stiffening element extending continuously in the toroidal interior cavity from a crown interface connected to a radially inner face of the crown to a bead interface connected to an axially inner face of the bead. the stiffening structure is distributed circumferentially over the circumference of the tire, the axially outermost stiffening element interface is positioned, with respect to the equatorial plane (xz), at an axial distance a at most equal to 0.45 times the axial width s, and the radially outermost stiffening element bead interface is positioned, with respect to a radially innermost point (i) of the axially inner face of the bead at a radial distance b at most equal to 0.5 times the radial height h.
