All of my vehicles have at least 78% nitrogen in their tires, considerably more if you believe that oxygen leaks out faster than nitrogen.

Ditto to what XS650 said.
That being said, my Hyundai Dealer puts Nitrogen in all the Hyundai's they sell, including my Genesis. In addition, they check and top off tires FREE.

Same here.

I have it in my Taurus and feel that is more stable in temp swings vs air.
It's free for my tires.

Guys, anyone who took general chem knows that air and pure nitrogen are going to behave identically under mild temperature swings! (120 F swings) There is no real benefit to nitrogen. Oxidation of tires occurs on the OUTSIDE, not the inside. This is another example of buying something that has no value in the long run. Spend that money on better tires or a rotation or something meaningful. If it is free, nice if you don't have to do extra work for it but to what end?

+1. Nitrogen is the current snakeoil today. Regular air you breathe has almost 80% nitrogen. Maybe you they will combine a fuel filter magnet with the nitrogen so you can gain 10mpg for a low price of $19.99...

For what it's worth, Michelin supports and endorses the usage of nitrogen tire inflation.

That is a strong statement. It has a lot of tough competition. How about ''synthetic'' brake fluid?
Has the EPA tested nitrogen?

Say all you want......I think it is more stable holding pressure.

The EPA has tested almost all the ''gas savers'' and found all of them useless.
Jeeze, it's been a whole month since the last thread on nitrogen. https://bobistheoilguy.com/forums/threads/nitrogen-tire-fill.63566/

In my OPINION, the largest advantage of a higher concentration of nitrogen (look at the websites for the products used ... the one at Costco claims, IIRC, 95%) is that the concentrators remove much of the water vapor. I believe that water vapor causes more pressure change with temperature than oxygen or nitrogen. At higher pressures (aircraft tires and industrial hydro-pneumatic accumulators) oxidation is a more significant issue.
Is less oxygen better ... hard to say no. Is it MUCH better at the <50 psig of automobile tires ... hard to say yes. Is it MUCH better at the 50 psig to 150 psig of truck tires ... more than with lower pressures, but IMO, not much.

Nitorgen is more stable holding pressure in MAJOR temp changes. Jets/planes use Nitrogen in there tires due to them going from a 100+ degree runway to a -70 degree alltitude of 40,000 feet and then back to a 100+ degree runway. In that case, yes Nitrogen is great. In a car, it really has no effect.

Guys, seriously.
Nitrogen can sometimes make a small, micro difference in tire performance. On an ultra high performance race car at 200mph that small benefit can sometimes make the difference between winning, losing or crashing.
For street cars, nitrogen simply makes the driver happy because it's really cool to use the same stuff as ultra high performance race cars that go 200mph.
It might be silly but if it makes people feel cool to be like their favorite race driver then what the heck. At least it's not obnoxious like [censored]-can exhausts or silly body kits.

We've had this discussion before and here's a link to some interesting data:
http://www.engineeringtoolbox.com/individual-universal-gas-constant-d_588.html
This means that Nitrogen IS more stable - 3½% worth!!
The real reason that aircraft use nitrogen is:
1) that is comes in 3000 psi bottles and that's easier than lugging around a compressor capable of filling 300 psi tires.
2) that it is required by the FAA in order to NOT support a fire. (My guess is that #1 came first and the FAA thought it was such a good idea, they make it a requirement.)

Finally, some good facts we can chew on that weren't presented in the old threads!
I also think Lorenzo made a good observation.

I don't get the 3 1/2% bit. Regardless of its molecular weight the idea gas law calls for the pressure of a fixed amount of gas in a fixed volume to be proportional to its absolute temperature. So double the temperature, and you double the pressure, be it hydrogen or uranium hexafloride. If you don't have any of the heavier oxygen or carbon dioxide molecules in your tire, you have to have more nitrogen molecules in your tire at the same pressure. So with a given temperature change, the pressure change is still going to be the same.
Now, one more point. No gas follows the ideal gas law exactly. Helium comes the closest. I have see tables of correction factors. They are larger for the likes of water vapor and carbon dioxide. Very little work requires using them. I was taught they exist in school, but don't think even there I was required to use them.
It sounds to me like the supporting combustion issue is the biggest factor.
