Abstract
A rim disc adjustable to different sized rims includes a rim disc and a steel ring. The rim disc has a plurality of engagement members provided near an outer circumferential edge. Each engagement member has a projecting edge on a front end of an upper surface to rest on an inner wall of the rim, a ridge, a stop and a fit aperture for the steel ring to engage therein. One of the engagement member specially has another stop under the fit aperture, and the other stop has a few engagement grooves on its surface so that the steel ring may selectably fit in one of the engagement grooves to enable the rim disc to adjust to different sized rims.
