A tyre (1), a mounting rim (2) therefor, and a ring (3) for supporting the tread (10) of the tyre (1) when running at low or zero pressure. The tyre (1) has a radial ply casing (13) on which the points that are furthest apart axially are radially very close to seats (12B) of outwardly sloping beads (12). Said seats (12B) engage sloping seats (23, 23', 23") on the rim (2), which may have at least one mounting well (22, 22'), at least one cylindrical portion (21) for receiving the elongatable and circumferentially unstretchable rubber supporting ring (3), and a rim flange (24).
