Yep, a good air dryer is money well spent. Draining the tank is obviously free.Do I drain water from my air compressor(s) every now and then? Yes because I don't want excess water vapor in the compressed air, whether I'm using the compressed air for filling tires or using tools.
I don't use my air tools for painting and I keep them oiled. So, draining is cheap and free.Yep, a good air dryer is money well spent. Draining the tank is obviously free.
I'm not that concerned about a minute amount of moisture in my tires (and it's much better than getting oil in them),
but my air tools get the cleanest air possible.
Unless you are running pure o2 in the tires, that's the last thing to worry about in a crash, considering that you are totally surrounded by atmosphere with the same o2 content as what's in the tires.If your're in an aircraft, or race car, where the oxygen could be an issue from a fire standpoint after a crash, yes.
Other than that I can't see a single reason to use nitrogen.
The pressure increase could be several PSI, depending on tire temp and amount of water. The higher the temperature, the higher the pressure (it becomes exponential). On street tires - no big deal, as in "I don't care."Interesting. I'll have to dig deeper and see if I can understand this. The little I saw during a quick check showed that air expanded quite a bit more than water.
And since the water content would (hopefully) be minute anyway, I figured that there would be no measurable difference.
Is nitrogen theoretically, technically preferable to atmospheric air in tires?........Yes.Depends on where I fill my tires up, I guess. We have very little oxygen in the air here at home.
Anyway, I must've fallen for part of the nitrogen propaganda on that one.
Regardless of any water content, I'm painfully familiar with how much the pressure changes with our common 50 degree swings in a day. Then there's the heat being generated from driving, and add to that what 5,000 foot elevation changes do to it.The pressure increase could be several PSI, depending on tire temp and amount of water.
Hopefully, you find this information helpful:Regardless of any water content, I'm painfully familiar with how much the pressure changes with our common 50 degree swings in a day. Then there's the heat being generated from driving, and add to that what 5,000 foot elevation changes do to it.
Driving alone can easily amount to 8 psi or so on cold mornings.
Well, I try my best not to get any tires up to 212 degrees. Also, I balance even my trailer tires, so the shaking is minimized.That is what is going on in the tires. If the water was on the verge of boiling and you shake it, the pressure would go way up and it might explode.
... the rise in pressure from water is exponential with high tire temps.
That is a very good point, Zinga. And it's really when I only cruise along, at 100-120 in a 55, that I do.If you're thinking about cops, you're not going fast enough.
