nitrogen gas
I was over at costco looking to get a tire rotation and they said they used nitrogen gas to fill the tires. they said that the gas resists expansion or compression due to changes in the temperature.
is there anything bad associated with nitrogen gas in car tires???

Nothing wrong with nitrogen but I think they're feeding you a line of
that stuff costs a whole lot more than free air! They might add a little but I'm sure it's not pure nitrogen - it would be way too expensive.

It should be pure nitrogen, its the latest fad in the tire world. They sell units that remove the nitrogen from air through some form of membrane. There are a few different models from a few different companies available. I don't think its going to catch on, (i) its expensive and you would have to charge for it, (ii) if you ever top off with regular air the benefits are lost. People are NOT going to like paying for optional air, I asked and explained the benefits and the average consumer does not care! The benefits are that its less likely to migrate through the tires inner liner and that it has NO moisture in it so it does no damage to the liner or the wheel and also weighs less because of this. Tire manufacturers have been building tires to resist these factors for years and have gotten really good at it, besides that air is available just about everywhere for free- if your tire goes low good luck finding a no2 fill station. Then you'd have to bring your tire back, have it deflated and reinflated with no2 and then have the percentage of no2 tested- below 98% the benefits are nonexistant.
Needless to say, I've looked into buying into this and deemed it not worth the investment- for me or my customers.

And since regular air is roughly 70% nitrogen anyway, I can't see the extra 30% of nitrogen making that big of an impact.

Still, it's a fad. Some Type-R loser will still think it's the latest and greatest thought.

I'm sure someone has tried it in the past... it would be a great way to make your car fly!

Nitrogen is used in high end paintball guns as it's density varies alot less when exposed to a wider range of temperatures. It does not expand or contract as much causing more consistent tire pressure, which, in some small way would contribute to better gas mileage. I am not saying it makes a noticable, but it's properties are much more consistent from freezing temperatures to the hottest summer temperatures. Also, if you were to top off and put 1 psi of air to 31 psi of nitrogen to top off, that would be 3% air in your tire versus 97% nitrogen. That would be a neglible amount of air to truly affect the benefits of the nitrogen. It is just another example of race technology coming down to consumers where the benefits aren't as noticeable as no ones car is being pushed to F1 limits.

I still don't believe that expansion can be the reason. All gasses expand and contract with temperature changes. Are you sure that it is due more to the fact that the nitrogen will not react with the rubber compounds in the tires and the metal in the wheels?

Expansion is the reason.
I'm a pilot and we use only nitrogen in aircraft tires so they won't blow due to expansion as we climb to cruising altitude. Also, nitrogen is very inexpensive, but the bottles and associated regulators are costly.

All this talk of the benefits of nitrogen are insane. Just use regular air!! The advantages to using nitrogen in your tires, especially for the average driver, are not strong enough to warrant paying for it. I am also a pilot, and yes nitrogen IS used almost exclusively in aircraft for the reasons already mentioned. Hydraulic accumulators, tires, shocks......all of them are serviced with nitrogen.
But this is nothing compared to the guy that went through the trouble of servicing his tires with helium to reduce the rotational mass. He actually did the math and found how much weight in air he was saving when the wheel was spinning. Crazy. It was in a Sport Compact Car issue about a year and a half ago.

I haven't read one post in this thread that makes sense. Almost all forms of racing use Nitrogen to fill the tires. Why? Because putting 100% Nitrogen into the tire means you aren't putting any moisture into the tire. It's not that Nitrogen has any different expansion than 'air', it's the fact that you aren't putting any water molecules into the tire that definitely do expand at a different rate. All it does is give you a more linear build-up of pressure in the tire.
And for everyday cars, air is fine because you aren't experiencing the same pressure buildup a race tire is...

Grubbs Infiniti (Dallas) is putting Nitrogen in all of its cars starting March 1. Apparently there's so many folks complaining about the Tire Pressure monitor going off (due to pressure changes cause by temp changes) that they rather fix the problem with nitrogen in the tires.
I have a feeling this will be more and more of an issue now that more and more cars have TPM systems.
The more I thought about this the more it makes sense. Maybe GM should offer nitrogen filled tires on all of its cars instead of OnStar as a safety measure. It would be cheaper and overall I think it would make a bigger diff safety wise (prevention vs. reaction)

I use Argon. Same as I use to inflate my drysuit for diving.
