Motor vehicle tubeless tyre has inner chamber that expands to block a sidewall puncture and limit pressure loss

摘要

The tubeless tyre (10), having beads (11) sealed with a wheel rim (12), incorporates a toroid inner chamber (30) with a skin (31) of a deformable elastomer material over a supporting frame (311). In the event of the tyre sidewall (12) being punctured the skin is able to expand quasi-instantaneously to block the hole at least temporarily and limit any loss of pressure in the tyre.
