CO2 Aluminum bottle for filling tires

I was at a swap meet today. I bought a small Aluminum CO2 tank. It's about 2 1/2 ft tall. I thought I could have it filled with CO2, and use it for tire air. The tank does not have a regulator, but a air chuck attached to the tank valve. Will CO2 be ok for tires, and can a air chuck be attached to the valve, without a regulator. If nothing works, I can scrap it, and get most of my money back. I only paid 10.00 for it. Stan

I don't think you would want to hook an air hose to a tank with 800 lbs of pressure without a regulator. But I don't see why you couldn't just air it up with your compressor and use it that way.

Old tires can explode with just a regular air compressor, so it's not good to go with any thing that could have higher pressure. I'm with Jon.

My question: Why would you want to use CO2 in your tires?

Why not?
That's what off-roaders carry to run air tools and reinflate tires without an air compressor.

Question is, is it a co2 tank or some other kind of tank?

Use air. It works and is free. Co2 is
OK but you need a regulator to prevent radical over inflation. Also, high pressure air can get blown into and under skin, causing an embolism. Which can be fatal!!. Jim

That is why I am asking my question. I am reading people with off road vehicles are doing it. Stan

That is what we use at the shop,20#co2 and a hose.(keep the tank upright,you really do not want liquid co2 in your tires.)BTW the tank will have about 300PSI in it.

I have a portable air tank. I can put around 100 psi in it. It will fill maybe one tire. Stan

It can be used but you need a regulator to limit the out pressure so the line does not blow.
You can buy small regulators without the gauge to save some money.

I once saw a guy at a pull a part junk yard with what looked like a scuba tank.
He was using it to run a air gun.

You use co2 because of the enormous amount of air you can carry in a small package.

With regular air you only have the air you can squeeze in the tank.
With co2 you have a liquid. As you use air out of the tank the liquid in the bottom turns to air providing more air to use.
Same principal as propane in a tank.

For those scared of putting a HP tank on a tire, without a regular, stop worrying. The only way someone is going to blow up a tire like this is to be absolutely stupid.

Personally I charge accumulators with nitrogen all the time. The nitrogen is in the tank at 2000 psi, give or take depending on how much I have used. I routinely charge to pressures anywhere from 30 to 850 psi with no issues whatsoever. I've got a guage on my setup since it's a special type fill valve, you have to have everything attached tight, and sealed, to put the charge. Even so, I just go a little at a time until the correct pressure is reached. If I overshot a little, I just let a little out until the pressure is correct.

To fill a tire, all you'd have do is put in a little pressure, and then check the tire. If there's too much, hit the Schrader valve and let a little bit out. Remember it's the volume of gas that gives you the pressure. In other words, using round numbers, a tire with 50 cuft of air will read 10 psi, while one with 100 cuft in it will read 20 psi. If you only put in 50 cu ft you'll only get 10 psi.

Like I said, that's just using round numbers as an example, but the fact holds true regardless of the gas used.

In the end, again, unless you hook up a chuck, and turn the valve on and leave it, there's no real chance of blowing up the tire as some are afraid might happen.

If it's still up to date, legal to fill.

But you'll need a high pressure hose. At 80F you're looking at almost 1000 PSI!

Be careful!

I have portable air tanks at both residences, but I have a 12 volt compressor in each vehicle. They're kind of slow, but they get the job done. We were up in CA on a fishing trip once and had a low tire, it wasn't easy to find any air!

If your looking for a larger supply of air thannan air tank go ahead, just get a regulator. But don't try it without the regulator.

Scuba tanks-I'm an avid wreck diver-we have used air chisels connected to a scuba tank at 150 ft deep to get portholes off. Good for two dives on average. Same setup has been used to reinflate tires after a beach dive. Lol.

Why do you want to put co2 in your tires? I just fill them with the air compressor. Must be a California thing.

In some places I work with my tractor I would need a 40 mile long hose connected to my compressor. Stan

I used a Nitrogen tank on my race car tires .Had a regulator on it but didnt know it was bad . Went to use impact to take tire off ,thought world come unglued . Lug nut went flying clear across pits . Not sure a CP734 impact is to be used with 500 lbs of pressure , lol

Buy a regulator and use it. They aren't expensive and to not use one on high pressure hoses is plain stupid. Has anyone ever pumped up a tire and not felt the air when pushing on the chuck? The HP is going to cut through your fingers like a hot knife through butter.
