My father bought a new '49 Ford four door and it had the plastic "white walls" on it. I remember the Pep Boys Auto Parts chain selling what used to be called porta walls. This is before tubeless tires were standard and everything had tubes in the tire. Yes this was some time ago. What you would do is let the air out of the tire and mount the porta wall white walls between the rim and the tire. Air up the tire and the porta walls were held in place. I remember seeing cars that people had gotten to close to the curb while parking and tear these things. The would be going down the road with part of the porta wall flapping the fender.
