beads with bead cores;
an emergency support body, mounted on the wheel rim and
positioned inside the pneumatic tire, that includes an emergency rolling
surface to support the pneumatic tire in case of failure;
the emergency support body comprising a surrounding ring torus
composed of a rigid material with a bowl-shaped cross section having at
least two radially outwardly arched sections forming axially exterior
peripheral areas separated from each other by a radial depression,
wherein, when deflated, the tire is capable of riding on the outwardly
arched sections and the radial depression;
the ring torus being formed to maintain the bowl-shaped cross
section in an emergency roll; and
the emergency support body being resiliently supported over both
