Anyone recommend a place is north county coastal or UTC area that refills CO2 tanks while you wait? I have a tank I need to refilled.
Thanks for the help!

The normal CO2 regulators are rated at very low pressures because they are mostly used for, as mentioned, soda machines. I was taught this when I went to upgrade my go kart air cylinder for use with the Porsches. Go kart tires typically take less than 20 psi. The regulator I had, and/or the air hose probably would have failed with the new "scuba-sized" nitrogen tank I traded for. I sprung for a nice 2 stage regulator that shows tank pressure AND line pressure.

Just a note to let you in on some info. 4 wheelers have been using CO2 fo a long time to re-inflate their tires after airing down for off roading. One thing you need to know is that CO2 expands much more with heat than air so be careful using it on a regular basis in on road vehicles as you could over inflate by mistake. Most of the off roaders will tell you to drain the co2 out of your tires and reinflate with air once you get home just because of this problem. CO2 also introduces moisture into your tire, I know because after pulling my tires off my rims the rims were very rusty (steel rims on the Jeep) inside and I was warned of this in advance. One more thing and I dont know if it is true but the guy at San Diego welders supply in El Cajon said that CO2 erodes rubber.
Just a thought,
Dave

As it converts to a gas the CO2 nearly freezes and carries very much moisture. It also increases in pressure at a much steeper curve than oxygen as related to temperature. The post mentioned that the CO2 would be used in a motorhome which I assumed would have steel wheels. As for data to back it up i'll look for that when i get back from my business trip. Most of this info was picked up in my last 25 years of calibrating pressure gages for the aerospace ind. and come from the Ansii and ASTM (american society of testing and materials) and much of this is also from memory. As for the eroding of the rubber, that was info from the manager at SDWS and I also took it with grain of salt, but on my jeep i usually get 50 or 60 thousand miles out of a set of tires.
