<p>The invention concerns a tyre (1) comprising two beads (3, 3'), a crown and sidewalls (4, 4') linking the crown to said beads, said tyre being reinforced by a carcass reinforcement (5) anchored in each bead to at least an annular anchoring element (30, 30'), each sidewall comprising an additional inextensible sidewall ring (8, 8') axially located inside the axially outermost carcass ply and a coupling profiled section (80, 80') radially located between the annular bead anchoring element (30, 30') and said sidewall ring (8, 8') and axially located inside the axially outermost carcass ply. Said tyre is characterised in that the segments of the straight line passing through the centres of gravity of the sections of the bead anchoring rings (30, 30') and through the centre of gravity of the rings (8, 8') of the sidewall located on the same side form with the axis of rotation different angles, respectively, β1 and β¿2?</p> |
