Can I put a compressed air tank under my Suburban?
In college my friend had a tubular bumper made for his Samurai and the welder put a schrader valve on it. It allowed him to put compressed air in it to refill his tires after he went on the sand dunes.
I know they make portable tanks to carry but I was wondering if anyone has ever heard of a tank that could be installed under the Suburban. I'd like it to be able to hold enough air for all four tires.
Links or thoughts?

Why not install a compressor and an air tank?
Quick Air and VIA Air sell inexpensive and fast compressors.
In the back or along the frame rails offers lots of spots to mount air tanks. My previous Suburban had two 4 gal tanks along the frame rails with a compressor, the present Suburban just has a VIA Air compressor. You need more than just an air tank to fill tires it requires either a large volume of air or high pressure. Most tanks for air storage are only rated between 250 and 500 PSI.

My uncle came up with a pretty good idea for air tanks, 18-wheeler tanks. They're usually nice and sleder, but long. Perfect to tuck right inside the frame rails on a Suburban. I don't know how many gals or PSI they're rated for, but I imagine they're 5 gal tanks at at least 125PSI. When I get time to do an onboard air setup, I'm going to find and snage me a couple of 'em and make some brackets to bolt them to the frame rail with.Christopher

They last about 5-6 years before needing to be replaced, you can custom make them for your application and they cost half the price of available premade tanks. I've been using PVC tanks on my rock crawlers for years. Schedule 40 is rated to 600psi (most compressors are only rated to 120-160 PSI) and cracks when damaged instead of exploding like steel or aluminium.

the land rover had tanks and under most tow truck have them and of the smaller welding tanks will work. watch out if you use the PVC it will explode and send large chunks everywhere --if me i not use the plastic. use the correct tank. there is many different sizes and many different ways to fill them or get the co2 porta tank and run air tools and anything you want air in....mikeMichael Collins

CO2 would be ideal for most applications but in some areas local restrictions make it hard to get the tanks recharged and they too need to be hydrostatically checked every 5 years or they cant be recharged.

Tim, Do you have any photos of your tanks? I assume the ends are taped and threaded. How did you put in the schrader valve?

i understand your words on PVC, but i seen and seen pictures of PVC home made tanks exploding and doing damage. and DOT would not inspect your tank since it was not a factory item. PVC is rated to 600 PSI it states so about every 12" on the tube. so it is your choice use PVC if you like but I will not even a fine is better than a pine box to me.............mike
