The problem of full wheel covers "walking" around the rim (and cocking/chafing the tire valve) predates the use of radial tires.

The full wheel covers on my V8s have a coupe of special teeth, which are adjacent to the valve stem opening, upset from the metal between the ring of teeth (inboard) and the rim of the cover (outboard). These extra teeth correspond to a couple of divots on the OE rim. I believe this was intended to help keep the opening centered on the valve AND prevent the cover from "walking".

I don't have '54 full wheel cover handy, but suspect it has the same feature.
