Abstract
A stepstool (20) configured for mounting on a vehicular tire (22) includes a support frame configured to rest against an outer surface (38) of the tire (22). The support frame includes a first upright support (24), a second upright support (26), and a third support (28) coupled to each of the first and second upright supports (24, 26). A platform (30) is attached to the support frame. A retaining bar (36) is configured to rest against an inner surface (40) of the tire (22). Chains (32 and 34) link the retaining bar (36) to each of the first and second upright supports (24, 26). The chains (32 and 34) are directed over an upper circumferential surface (83) of the tire and wrap around the upper circumferential surface (83) to hold the platform (30) securely on the tire (22).
