SCUBA tanks for filling RV tires?
I have a vague memory of some folks getting a SCUBA air tank pumped up to very high pressures, then carrying the tank (with a pressure regulator) to quickly and accurately fill RV tires. Do any of ...

there are some silly answers in this thread concerning the original question.....
SCUBA cylinder for inflating tires....... NO Problem.
SCBA cylinder for inflating tires.........No Problem.
Nitrogen cylinder for inflating tires.....No Problem.
Helium cylinder for inflating tires.......No Problem.
these sources also work well for operating an air tool such as an impact wrench for loosening the lug nuts. but unless the cylinder is big, it will empty quickly running an impact gun..
we use a scuba cylinder all the time when using the brad/staple driver for trim and paneling install work...
all one needs is a single stage regulator that fits the respective cylinder, because there are few air hoses that are safe to be used at pressures over 200psi.
all the cylinders mentioned here run a minimum of 3000psi....
a two stage regulator set up, like used with SCUBA and SCBA, takes tank pressure thru the first stage down to an intermediate pressure of around 150psi... the second stage of the regulator setup is what delivers the breathing air to the user AS NEEDED by VOLUME, rather than pressure.. the pressure is only there to push the volume as needed.
so any single stage regulator that can reduce tank pressure to 150psi is completely safe to use as an inflation regulator.
its a fact that tire shops run between 150 and 170 in their lines, and then reduce it to 120psi at the tire machine or tire bay.
in addition, when inflating a tire, one should never connect a locking chuck to the stem and walk away... but properly put some air in, and then check the pressure and add a bit more as necessary.
but I will agree that if someone who is wandering thru life trying to win a darwin award were to connect a hose to a tank without a regulator, there would be a a high degree of danger, but doubtful it would be a tire explosion because the line carrying the air from the cylinder would rupture before the tire.. an automotive, truck or trailer tire in good condition will take well in excess of 200psi without exploding. BUT it can cause damage by over stressing the belts and tearing the rubber loose from them.
