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.

Abstract: A tire is provided with a tread that includes first and second sectors and grooves. The second sectors are formed of a rigid reinforcing compound. Each of the first and second sectors has a contact face intended to contact a road surface when the tire is in use. Each groove includes sidewalls and a bottom, and extends from an end of an adjacent contact face. A depth P of each groove is measured in a radial direction between its bottom and a position corresponding to a radial height of the adjacent contact face. At least one of the second sectors has a contact face that includes a recess having a depth p of less than 2 mm, as measured in a radial direction from a surface of the recess to a position corresponding to a radial height of an adjacent first sector.

Abstract: Adapter for a rolling assembly intended to be fitted to a passenger vehicle, with improved mountability and a high capacity for absorbing large deformations in the event of pinch shocks. The adapter has reinforcing element (15) of the axially outer end (9) wholly situated axially on the outside of bearing face (21) and radially on the outside of adapter seat (18), and a main reinforcement (17) having a radial superposition of at least two layers of reinforcers, the reinforcers being mutually parallel within one and the same layer and crossed with one another from one layer to the next. Each of the layers of main reinforcement (17) comprises reinforcers which make, with a circumferential direction (XX?) of the tire, an angle at least equal to 30°, and coated with a polymer material having an elastic modulus at 10% elongation at most equal to 70 MPa.

Abstract: Adapter coupled between a tire bead and a rim, and having an axially inner end mounted on the rim seat. The adapter comprises an inner reinforcer, an axially outer end that comprises an outer reinforcer, and a body that connects the outer and inner ends to form a single piece and comprises one main reinforcement that connects the outer and inner reinforcers. Substantially cylindrical adapter seat receives one of the tire beads, the seat being situated at the axially outer end of the body. An adapter bearing face is substantially contained in a plane perpendicular to the axis of rotation of the tire/rim rolling assembly, the bearing face being situated on the axially inner face of the axially outer end. The reinforcing element of the axially outer end is axially situated entirely on the outside of the bearing face. The body comprises, facing the adapter seat, an annular seat reinforcement.
