Probably not, compressed air has water in it unless you run it through a dryer. It should evaporate into the air inside the tire when it warms up and it'll be vented next time you air down. Some tractor tires are run with water and a calcium mixture for added weight. > I've rigged up a CO2 tank to inflate tires with.

Will this do any bad to my tires? Assuming its dry CO2, you are probably seeing dry ice forming inside the line. You can make dry ice by putting a cloth bag over the outlet and vent the tank into it, Vapor escapes, dry ice is left, lots of fun at Halloween parties! > If it freezes the reg. when it's 107 outside..this may not be such a > good idea when winter rolls around. That's one of the drawbacks of CO2 systems, pressure and delivery rate requires heat.

Any idea why they add calcium? Same is done on 'reachers', the forklifts with extension-arm, but on the rear, as counter-weight. Always wondered what it would do on a 4x4, to lower the center of gravity....low speed 'aired' down of course, high-way speed at full pressure might get interesting....:)) -- Bye, Willem-Jan Markerink The desire to understand is sometimes far less intelligent than the inability to understand [note: 'a-one' & 'en-el'!] FROM: Mike Romain SUBJECT: Re: The first of many: Question about water in tires DATE: Wed, 06 Jun 2001 14:04:48 -0400 ORGANIZATION: Bell Nexxia NEWSGROUPS: rec.autos.4x4 Willem-Jan Markerink wrote: > > In article <3B1DB0C9.A1AF512F@home.com>, > Roger Brown <4crawler@home.com> wrote: > >Maximum Frog wrote: > >> > >> I'm wondering if moisture in tires can hurt them. > > > >Probably not, compressed air has water in it unless you run it through a > >dryer.

They use it up north on the roads where it is too cold for salt to work. It is also used in the water to make concrete if the pour has to be done in below freezing weather.

Same compound is used to solidify loose sandy soil in road construction and helps control dust, so its probably something a farmer or road builder would have around.

The water/ice in the CO2 gas issue is in their FAQ: http://www.powertank.com/faq.html The regulator icing up is simple physics, liquid CO2 evaporates to gaseous CO2, a process which requires heat, that comes from the air. Cold air causes water vapor to condense on regulator where it freezes (the CO2 boils off at around -100F). Go out to Death Valley and air up, you won't see any ice buildup (low humidity). Same thing will happen to a propane tank in cool humid weather. In fact that line of ice or condensation is a handy way to find the level of liquid in the tank.
