HPA tank or a 20 ounce co2 tank for filling up car tires

[MiteyWhitey]

I need some help finding out a way to hook up an adapter on my HPA tank or a 20 ounce co2 tank for filling up car tires. This is for a trip to the infamous Rubicon trail. After airing down our tires, i have heard people have used their co2 tanks or hpa tanks with some kinda of adapter to fill their tire psi back to normal. Anyone heard of this who can help me out.... thanks.

You will need a regulator to drop output pressure down from the 3000-4500 psi HPA or 1200 psi CO2 to a somewhat lesser presure. You may be able to use an inline reg, then a length of flexibe braided hose, and then a valve stem adapter. Easy.

BTW, I have seen a video of an Icelandic procedure for reseating a bead on a tire that was aired down too much and slipped off. They squirt a bit of lighter fluid inside the tire, and then expose it to a flame. The tire is reseated EXPLOSIVELY. BE VERY CAREFUL DOING THIS. In fact, DON'T do it unless you ablsoutely have to, as death or injury could result.

Yeah... but they were running those tires at 4 psi and driving on icefloes in the artic. It could probably get you to the next exit tho. I have a bike tire filler that accepts 12gs. I used it on my car once but the co2 chilled WAY too fast to get more than 2 psi per cartridge. Perhaps you could get one of these, then put a dummy 12g in the side, drill and tap a hole for 1/8 npt.
