Nitrogen

Well you're lucky. You made it to 28 posts before someone mentioned a damper.....Slackers! ?

i took this advice and had my damper filled with N2

I use the air from the air compressor to fill them up. 80 percent air, 20 percent water.

While it did get a bit derailed, his question did indeed get answered very quickly.

And then the answer got expounded upon just a wee bit...

Sometime, it might benefit one to use it. Honda for example, has a funny tire monitoring system, based on RPM of the tires. The idea being that a low tire has less circumference, hence higher RPM for any given speed. Honda says, to prevent issues with the system, use only nitrogen. OkieDokie Honda, then why do your dealers charge extra for it?

Sort of reminds me of dealers who charge you for disposing of your old oil. Geez, they "SELL IT"! Fact is, if you tell them you want the old oil back, they tell you the EPA requires them to recycle it!

Bottom line... Fogitaboutit!

The whole Nitrogen myth started many years ago when some racecar drivers brought nitrogen cylinders to the track... Not because nitrogen is inherently more stable , but because air compressors condense a lot of water from the atmosphere and it ends up in the tires.
Water vapor does affect tire pressure unpredictably as they heat up.
There is no significant difference between pure nitrogen and completely dry air as it relates to tire pressure.

I once saw a man sell a jug of Kool-Aid without sugar to another driver at the race track just to prove a point.
He said the orange liquid was a surface friction reducer, proving that some driver's will do anything for the slightest edge

WAIT...now your going to compare "completely dry air" to what ??? Completely "wet" air ???
If pure nitrogen is completely dry, than does that mean that "regular air" which is 78% nitrogen is 22% "wet" ??? Is there any type of government regulation as to what percentage constitutes "wet air" ??? At what percentage does the air become "moist" ???

My Ranger has those little green valve stem caps showing the tires were filled with Nitrogen. Is it worth finding a nitro fill station or just top the low ones off with regular air? Never had nitrogen filled tires in any other vehicle before.

My tailgate damper is filled with nitrogen. You should see how well it opens & closes! ?

No.

Fill em up with mustard gas.

In my experience, Nitrogen is worth the extra expense and effort. The pressure does not vary depending on temperature, and the tires hold their "air" much longer. Opinions may differ...

RH60%+ would be considered moist air as this would be the point after you would start to expect condensation into structures and building water damage (ie. mold). On colder climates this could be even RH40%.

Now if you consider that you put 32'C RH90% air into a tire at two atmospheres (bar) and it cools down to -1'C, you would expect a hefty 24 grams ice block inside your tire. Could mess up the tire balance until it melts, but the 24g might be a bit light side to be noticeable.

When Airco or its ilk process bottled gasses, they do so to a purity standard and thus bottled gasses are devoid of moisture when delivered.
Ordinary air compressors simply compress ambient air and the process condenses water into the tank. mechanics don't normally carry around extensive air drying equipment like for instance a paint shop MUST have to spray a car (even HVLP)
"Wet" air affects tire pressure more than dry as the tires are heated.

Yeah I had nitrogen filled tires once, loved the little green valve covers but soon the dealer stopped supplying nitrogen. Guess it was a scam...LOL

We have really dry air here in New Mexico so fill your tires here. Plus it is lighter due to being at a higher altitude.
