This is a single rim that was on a 1950s Buick. I don’t know if that’s what it’s originally from. This is an single steel rim which has the clips that hold on moon style center caps. This rim will not fit over disk brakes, drum brakes only. The lug pattern is 5 on 5 inches. This pattern fits on some full size cars like cadillac, buick, Oldsmobile, and pontiac from the 50s and 60s.
