Years ago I bought a pair of 15x4.5 inch wheels with a 5 on 5 bolt pattern made by Kelsey-Hayes, and I can't work out what they originally came off. They are stamped: K-H 2 55 231724 I ***ume the 2 55 is a date code for February 1955, which looks about right as they are old-style wheels with no safety beads. They also look like they are made for 7/16 wheel studs. All this makes me think they are something GM like Olds or Pontiac but by 1955 they were 5-1/2 wide. Does anyone recognise them?

That was quick, thanks! Rover P4 from your link definitely looks correct ... The balance weights are interesting, and I had never seen that before either. There are two on this rim, and one on the other one I have.
