Abstract
A large annular ring is secured to a wheel rim to augment the load capability of a tire when it is partially or nearly fully deflated. The ring includes an outer elastomeric pad which contacts the ground as a tire collapses. An intermediate length of the ring serves as a brace against the buckling sidewall. As a result, the majority of load is assumed by the ground-engaging ring but the ring, in a state of equilibrium, braces the outwardly buckling sidewalls of the tire so that the collapsing tire is still capable of assuming a portion of the load.
