Abstract
An adaptor assembly for removably mounting a traction wheel that is a partially inflated conventional automotive or turf tire on a conventional automotive or trailer rim, to each of the driven wheels of a forklift. The adaptor assembly has a mounting assembly semipermanently attached to the driven wheel and a traction tire assembly including a spacer sleeve attached to the traction wheel. An anchor member extends through a bore in the spacer sleeve and threadably engages a central hole in the mounting assembly to anchor the traction tire assembly to the mounting assembly. Drive pins extending from the spacer sleeve engage small openings in the mounting assembly adjacent the central hole to transmit torque between the wheels. In one embodiment, the anchor member is hollow with an inner diameter larger than the hub of the driven wheel so that a protruding hub may be accommodated.
