My 12v tire inflator crapped out while I was in need. It seems a lot of them die while in the trunk of a car because of seals or cooked components. A foot pump would likely suffer the same seal failure.
I like the idea of the CO2 inflators but they're just too small for a car tire. I think on a 32" tire you'll get about 2psi per 12g cartridge, which isn't practical. The math suggests 90g cartridge would get you about 16psi, still not practical.
Which got me thinking about ways to store compressed air for emergency tire inflation that didn't require a big dedicated tank. Like a modified fire extinguisher?
Anybody done anything like this?
What about using something like a $6 can of R134a and a modified valve/hose? It's already pressure in a can and the valves/hoses are readily available.
Curious what you smart fellas come up with. Keep in mind, this is stranded on the side of the road and just plugged a flat use.
