Zusammenfassung:	The tyre, designed to be fitted to a wheel rim (10) with seats (11) that slope outwards and end in humps (14), has its beads (1) containing circumferential reinforcing elements (4) that anchor the radial ply carcass reinforcement and shaped to rotate during the final stage of fitting. The tyre differs in that the seating surface (81) of at least one bead has the connecting profile (82) between it and the lateral surface (83) of the bead is shaped so that the maximum and minimum distances (L1, L0) from the bead reinforcing element's centre of rotation (41) to two points on the connecting profile surface satisfy a relationship where K is less that one per cent, and K = (L1 - L0)/L1. The value K is selected so that the compression stresses in the zone of the bead corresponding to the connecting profile are much lower than the compression stress of the bead material that is in contact with the rim and corresponds to a compression deformation of one per cent.
