ABSTRACT:
An apparatus for allowing pre-assembly of a wheel and wheel spacer and a method of using the apparatus are disclosed. The apparatus provides a structure within the hub of a molded plastic wheel and a structure on a spacer segment for engagement of the two parts. A variety of embodiments are described in which the spacer can easily be snapped, screwed, or pressed into the wheel. This allows pre-assembly of the spacer and wheel so that when needed, a spacer need not be found or acquired, but is readily available to the user.
