Yes, that's what three of the rear rims appear to be. The fourth is the 3 piece with split rim like the fronts and is narrower than the other 3 on the rear. I won't know what shape they are in until I get them off, but the fronts weren't too bad. Some rust under the tube and flap, but nothing serious. Maybe I'll get lucky and the rear rims will be okay too. Then I'll only need to find one rim.
