When Mercury introduced its new body style for 1949, a wheel center was used that had previously served on Lincoln models. The hubcap mounting bumps were on a larger circle than on Ford wheels, so a larger diameter hubcap was needed. The 1949 version was a nearly flat cap with a square shoulder, and lettering on a raised ring around the edge of the face that read "MERCURY EIGHT". For 1950, the raised ring and lettering were deleted, resulting in a smooth, slightly convex surface with no decoration. Mercury ads showed these in combination with a trim ring covering most of the painted wheel, but perhaps the trim rings were an extra-cost option: Looking at Hop Up magazines from the early '50s, it's apparent that the 1950 hubcaps (and, necessarily, the matching steel wheels) were picked up by some hot rod & custom builders. Not a surprise, as the Merc caps' lack of ornament was consistent with the simplification favored by customizers of the day: Valley Custom used the stock cap & trim ring with whitewalls on a hardtopped '49 Merc: Chet Herbert used the caps, again with rings and whitewalls, on his iconic Deuce 4-door: ...and '53 AMBR winner Dick Williams used them, apparently for the first time on chrome reversed wheels, with blackwalls on his T: Over the years many other luminaries have used them, including Ivo: Brizio, Falk, and other contemporary builders have used them on chrome wheels, usually reversed in the rear, with WWs: While I was deciding about stuff to use on my '40 (you didn't think I'd do one of these designy threads without slipping in something of my own, did you?), I thought that the Brizio-style combination was the cleanest and most elegant of the traditional wheel treatments, so I shamelessly copied it on my own car: There's really no point to this thread other than to show off this simple combination of wheels & tires, an alternative to paint or full wheel covers, that has been around for more than 60 years.
