How about using a rich "ivory" or Cream" color. It would give you something nostalgic looking, to go with the wheels. Just make sure it isn't too white. Then nobody would notice the color.

It would also work in a two-tone with dark blue....or a deep aqua blue. If you wanted it to look early fifties, use solid colors. If you want something late fifties/early sixties, use a metallic blue or aqua.
