SCUBA tanks for filling RV tires?

O2 is very flammable if a tire should catch fire or explode. Is that a good idea?

Only with an oxidizer. O2 by itself is inert. You could always pick up a bottle of Nitrogen and be cool with that, green valve caps and all...

True but limited truth. O2 does not burn but it will cause almost anything else to burn very hotly, including rubber tires.

Do any of you have experience and/or opinions about this settup?

I know of it and the adapters are in the link above. I never did it because I didn't want to carry a tank filled to 3300 psi in the truck bed over some of those roads we go on. I would of had to construct a padded wooden frame or box for the tank. I also did not want to drag a delicate regulator around either. I see there is at least one rig above that eliminates the regulator.

Unless you have a scuba cert card you may have trouble filling a tank tho.

You would not want them filled with pure O2. First it is very hazardous, you haven't seen a fire until you've seen one fueled with pure O2. Second, it could make the tire rubber deteriorate very rapidly and convert those tires to bombs too. CO2 or N2 would be OK but you better label that tank, it would have to be flushed before using it for scuba.

I think CO2 is more common for this purpose. Check out Power Tank.

I've used one, and my FIL has one now. On a full tank you can fill numerous oversized offroad tires.

The only hassle is getting them refilled, but they are awesome while in use.

Don't get too hung up on steel vs alum tanks. For a comparable size the alum tank is a tiny bit heavier because a thicker wall is required for the pressure, but the alum tank will not rust, but it is easier to ding/damage.

Fancy but unnecessary. Suit yourself.

Work great for air guns (you can actually buy an air rifle now that will take medium sized game like deer. You recharge them with a Scuba tank.

Anything is possible and I believe there is an outfit that actually markets a Scuba tank set up for filling tires and running air tools. Not cheap though.
