'Lil Knee Scuffer
Found these odd size US Royal 28 inch tires nos that were stored for many decades.I didn’t know what size rim they fit so I brought them to a wheel builder . He said they fit tightly on old British roadster rims. They come up on EBay once in a while.he built them on reproduction aluminum rims that have a similar shape with paint and pinstripes. That and the brick shape is as close as you are going to get to the originals.Its also nice to have replaceable inner tubes.I wind up riding it much faster than the old bike was designed to go. I think this is as close as you can get and still be practical.
