Do you differentiate between hubcaps and wheel covers?

Same thing.

Car has many parts with accompanying names that generally describe their function (still not sure just what a plenum is though). All wheel covers are hub caps, not all hub caps are wheel covers. The more restrictive term is needlessly overdescriptive and is thus rejected in favor of the more general term that describes both analogous items.

I agree that I’m being pedantic. Before alloy wheels became so popular (early-'80s? – though I remember that ‘mag wheels’ existed when I was in the single digits) a hubcap was a hubcap. But no one is going to put a full-coverage hubcap on an alloy wheel; so I make the distinction.
