"Stock" wheels are 15 inch "innies" so called because the hubcap snaps onto tabs located inside the center section of the wheel. This wheel was used on 1961/66 F100's.
The stainless steel (Custom Cab) innie hubcaps have been reproduced, the painted version not.
Ford did not offer trim (beauty) rings for these trucks, but any 15" trim ring from a 1942/48 Ford/Merc Passenger Car (ribbed) will fit or 1949/51 Ford/Merc Passenger Car (smooth). Both types reproduced.
