Ah. Gap fillers.
I am glad that I have not seen spinners in a while. Where did they go?
Someone could take "floaters" (or make them "drill and tap the spindles and bolt the hubcaps on to the spindle after you make sure nothing hits (valve stem,hubcap tabsweights) (
Floating Hubcaps. | The H.A.M.B.)) and fabricate wheel covers that cover the rims, upper portion of the tire, wrapping around at least somewhat.
Someone posted wheel covers for buses like that, but they were to reduce run-over pedestrians.
