<p>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).</p> |
