Having been around for almost a half century ......... oops! a little
longer I've seen bunches of stored or manufactured pressure devices.
One if the coolest was the FLAT super shrunk spare tire. It came with a
co2 cylinder about the size of a caulking tube and was a wonderful thing.
It could be refilled and re used or if you needed a good cleaning you
could buy a new one.
If you've ever had a Snapper riding mower you know that they ship
$1600.00 mowers with $2.00 tires that stay flat and must be refilled for
each round with the lawn.
I used one of these cylinders and got a year supply of air for my mower
out of it. Next go around was a cheap 12v compressor, last only 6 months
but you can put the fill valve cam over devises on your bicycle pump and
keep a truckin'.
If you're one of the folks that never wants to change a flat you can put
60 psi in your spare tire and fill your flat from it with a jumper air
line.
