If I'm interpreting what I've read correctly, this "Chrome Clad" business started after automakers had problems with plating over aluminum, so to give the light weight of the aluminum plus the appearance that people wanted, they started with this chromed plastic kick.
I don't like plastic covers on wheels generally either. I had switched the Stratus that I used to have from 14" steelies with hubcaps to 15" factory aluminum wheels, I had put 15" American Racing Torq Thrust IIs on my Cordoba, I've got a set of 16.5" slotted mags for the '82 D350, my wife's car has factory aluminum wheels, my beater truck has factory chromed-steel wheels, and my daily driver has factory aluminum wheels. In the cases of the Stratus and the Cordoba, I switched wheels when I lost hubcaps. If I were in your shoes, I'd drive the current tires until their worn out, then look at the wheels. If they're in good shape, put a new set of tires on 'em. If they're scrubbed up, consider aftermarket wheels, and if you like the tire size that the car comes with, get wheels that are the same size as the stockers.
