Many, many years ago my dad owned a gas station. He had a strap that would go around the tire and cinch through a pair of D rings. Then you could inflate it with compressed air and that would make it even tighter as it went from flat to about an inch in diameter. It was about the size of a bicycle inner tube, but made of rubber interior and canvas exterior.
The image of that, when I was around 8 years old, has stayed with me ever since, but I have no idea why.
