I do this with aircraft tires for that very reason. Also corrosion prevention of the magnesium or aluminum rims. We do not use it on support equipment or fleet vehicles... For an Auto? It would give the same benefit that you would have in an aircraft but no one I know would pay anything like that for inflation. Nitrogen is also heavier than air by a fair amount potentially making for a harder ride at pressures over 35psi...

Good call Ricky. Pay $10 a tire to fill them? Screw that.
Yeah the benefit of no corrosion is nice But I'm not gonna sarcifice My ride comfort or performance due to heavier gas in the tires for a potential fuel milage gains. Not to mention It's FREE to fill my tires with air from my compressor. And I do keep a tire guage in my car, and I do use it. Well It's an Idea and I'm sure it will be debated as to whether it's better to use one versus the other. Just my $.02

This sounds like an alternative for people who take their car to jiffy lube, genie, satan, etc... The people who would rather pay a few bucks to not have to deal with (maintain) their vehicle. lazies.

its not the fact of being lazy, its the fact of having better wear on tires. Also if it does not expand or contract then that would in turn give better handleing. See what im saying?

I see what the advantages are... for a 1. race car - tire's, new to near melting temp in a couple minutes: traction/handling utilized at capability limit 2. aircraft - extreme altitude (temp) changes, corrosion, /\ 3. lazy - "Costco can tell I want the cheapest, easiest way to replace and forget about my tires"
Unless it's free like air, nitrogen doesn't seem worth any trouble for 98% of drivers. This is all my opinion of course.

The page says:
"The reason -- air contains moisture and moisture in tires expands and contracts, meaning air pressure fluctuates.
Nitrogen does not."
Unless I've forgotten everything I learned in thermodynamics, any gas confined in a fixed volume will change pressure as the temperature changes. Costco forgot the ideal gas law: PV = nRT. In a tire, V (volume), n (moles of gas), and R (universal gas constant) are fixed. So, P (pressure) will vary with T (temperature).

Damn Corbin! You one smart puppy!!! Get em baby!! Yes, all gases will fluctuate with temp. Dry pumped aargon will just as much as dry pumped nitrogen.

This isn't actually true.
Air is primarily nitrogen (about 79%) which has an atomic weight of 28 grams per mole (for molecular nitrogen N2). about 19 % is Oxygen, which weighs 32 grams per mole. The rest is misc gases, such as Carbon dioxide (44 g/mole), water vapor (18 g/mole) and trace amounts of other gases.
On the whole, pure nitrogen is lighter than air, albeit a small difference. This is given the same volume/pressure of air so you have equal numbers of moles. (avagadro's hypothesis anyone?)
Man, I'm a dork......
