I don't have a link to it right now, but I recently read about a test by Consumer Reports that established that tires lose a bit less in pressure when filled with nitrogen than with "air". Air leaks through the rubber, and nitrogen leaks slower.

I also believe the temperature of the tires doesn't rise quite as much with pure nitrogen, though I have no proof of that to offer.

nitrogen is a slightly larger molecule than oxygen, even though it's atomic weight is lower. Hence you will see less pressure loss. but not a lot less since your either filling with 80 percent nitrogen or 100 percent nitrogen.

I know for sure that we all need to go camping or at least find something to do.....

OP asked a simple question and this is what it has turned into.....:h.....:?....:S

Not to pick at nits horribly, but pure oxygen is not flammable. However, and this is a biggie, pure oxygen will cause things to combust at a spectacular rate, hence the issues with pure oxygen.

Thanks for beating me to the post. Oxygen is not flammable

I re-read it. You said this.
"and other critical pressure applications where oxygen under pressure could be a fire hazard".
Pumping "air" into a tire does not put you in a situation where you have oxygen under pressure. You are putting 79% Nitrogen under pressure but only 20% oxygen. No fire hazard.

Yes, I am aware of that.

Please reread my post. Nowhere did I suggest using pure oxygen in tires. I simply stated that the presence of O2 in critical applications can cause a fire hazard that would not exist without it. Remember that at 80 psi, (typical tire pressure for RV's) air is at about 5.5 times ambient pressure at sea level. That means that the amount of oxygen present is 5.5 times as high as standard conditions. Yes, I realize that it is still mixed with nitrogen. That's all.

When an aircraft slams onto the tarmac (crashes) and fuel tanks rupture, tires (at much higher pressures than 80 psi) usually rupture too fanning the flames with what? Whatever is inside. Oxygen if present, under pressure, with a real high probability of sparks too. That's just one reason why pure nitrogen is preferred in critical applications like aircraft.

This is exactly what I did, since I have several vehicles and several trailers with nitrogen in the tires. Only difference is, I purchased the 7 gallon aluminum tank from HF: Here

I bought one of those and it's a kick handing it to someone who doesn't know it's aluminum. :) I love it. Stupid price even with a 20 percent off coupon.

But you really need something that will hold higher pressures if you're going to be nitrogening up tires. Notice that use of nitrogening instead of airing. :)

11 gallon Portable Pressure TANK....good for 125 PSI

Although marketed as Air Tank you can fill with pure Nitrogen if you so desire.

SIGH.
None of that is true, Bill.
You could verify the stuff that pops into your head BEFORE you pass it along. It is real easy with things like Google.
