Tire for vehicle comprising a stiffening structure

A vehicle tire, intended to be mounted on a nominal rim and inflated to a nominal pressure P, the vehicle tire having an axial width S and a radial height H in the mounted and inflated state, and comprising a crown having a radially outer tread surface, intended to come into contact with ground, and two axial ends, each extended radially inwards by a sidewall of the vehicle tire and then by a bead of the vehicle tire, intended to come into contact with the nominal rim,

• wherein the crown, the sidewalls, and the beads delimit a toroidal interior cavity,
• wherein the vehicle tire has an equatorial plane passing through a middle of the radially outer tread surface and perpendicular to an axis of rotation of the vehicle tire,
• wherein the vehicle tire further comprises a stiffening structure, distributed circumferentially around an entire circumference of the vehicle tire and comprising two stiffening elements, each 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,
• wherein each stiffening element comprises filamentary reinforcing elements that are partially uncoated with an elastomer compound to make the stiffening element unsealed, except at portions of the stiffening element, which form the crown interface and the bead interface, respectively, and in which the filamentary reinforcing elements are coated with the elastomer compound,
• wherein the crown interface of each stiffening element is positioned, with respect to the equatorial plane, at an axial distance A at most equal to 0.45 times the axial width S, and
• wherein the bead interface of each stiffening element is positioned, with respect to a radially innermost point I of the axially inner face of the bead, at a radial distance B at least equal to 0.10 times the radial height H and at most equal to 0.5 times the radial height H.
