  • Patent number: 12583258
    Abstract: The tire (10) has a stiffening structure (50) comprising a stiffening element (52, 53) anchored in or around radially inner reinforcing structures (60A) and a radially outer reinforcing structure (70A, 70B). Each stiffening element (52, 53) extending from one of the radially inner reinforcing structures (60A) comprises a portion (523) extending in the toroidal cavity (35) between first anchor points. Each stiffening element (52, 53) extending from the other of the radially inner reinforcing structures (60B) comprises a portion (524) extending in the toroidal cavity (35) between second anchor points. The portions (523) do not cross over in the toroidal cavity (35). The first anchor points are axially on the other side of the same side of the median plane (M) of the tire (10) as the second anchor points.

  • Patent number: 12472775
    Abstract: The tire (10) comprises a crown (12), two sidewalls (30A, 30B), two beads (32A, 32B), an inner surface (33) delimiting a toroidal cavity (35), and a stiffening structure (50) comprising a stiffening element (52) extending continuously into the toroidal cavity (35) from at least one of the sidewalls (30A, 30B) or one of the beads (32A, 32B) to the crown (12). The stiffening element (52) is anchored in or around: a radially inner reinforcing structure (60A, 60B) arranged in the sidewall (30A, 30B) and/or the bead (32A, 32B), the radially inner reinforcing structure (60A, 60B) being distinct from the circumferential reinforcing element (40A, 40B) situated on the same side of the median plane (M) of the tire (10) as the sidewall (30A, 30B) and/or the bead (32A, 32B), and a radially outer reinforcing structure (70A, 70B) arranged in the crown (12).
