摘要： A tyre comprising two beads (30), each bead comprising an annular reinforcing structure (40); a crown comprising a tread (65); two sidewalls (70), each sidewall extending between a bead and the crown; a carcass reinforcing armature (85) extending from one bead to the other and anchored within each bead to the annular reinforcing structure; and a membrane (91, 94) situated radially on the inside of the carcass reinforcing armature. The membrane comprises a membrane reinforcing armature (91) anchored in each bead to the annular reinforcing structure, and an airtight layer (94) of rubber mix, the membrane being arranged in such a way that part of the membrane together with part of the carcass reinforcing armature delimits a chamber (100) extending transversely and circumferentially, this chamber being situated radially on the inside of the carcass reinforcing armature and, to a large extent, under the crown. The chamber is filled with at least one fluid. In any radial section, the curved length Lm of the trace of the surface of the chamber delimited by the membrane is greater than the curved length Lc of the trace of the surface of the chamber delimited by the carcass reinforcing armature (Lm > Lc).

摘要： The invention relates to problems caused to tires by impacts due to obstacles on the road, such as running into a pothole or the edge of the sidewalk. In this case the wall of the tire between the top and the bead can be pinched between the protuberance of the rim gutter and an external obstacle when the impact between the tread and the obstacle causes the closure of the internal cavity of the tire, momentarily giving rise to high dynamic compression stresses perpendicular to the wall of the tire which can lead to breakage of the reinforcements. An elastically deformable protection element with a high rigidity modulus in the direction of these stresses is used to absorb, at least partially, the stresses, for example by providing a coating layer of rubber containing grooves on the interior wall of the tire.
