As far as I can tell from the parts manuals and supplements for the Aero, trim rings for the wheels were never an accessory. Full wheel discs were optional in 1952-1954 and standard on the 1955's (except exports: according to the registry, they all came with the 1954 dog dish).
According to the registry and corroborated by the parts manuals:
1952's just had the corporate embossed "W" and no color on both the hub cap and the full covers.
1953's were like the 1952's except they had the "W" (unpainted) in a circle of red on both the hub cap and full covers.
1954's were like the 1953's except they added a single red ring around the red circle on the hubcaps. Full wheel covers had two rings and some were green or blue instead of red, depending on body color. I have never seen green or blue on the hubcaps, but I found a pic on the internet of a black Ace Deluxe with black instead of red on it's hubcaps - I think that was owner induced.
1955's looked exactly like the 1954-55 Kaiser full wheel discs except it had a "W" instead of a "K."
I'll post pics later if y'all want.
