As a purified gas, it’s dry going in as opposed to compressed, atmospheric gas.
I wouldn’t spend a cent on it myself but if someone wants to fill my tire(s) with it, won’t hurt so no issue.
If you search, you’ll find many reasons to use nitrogen. Just about all of them are bogus. It makes no practical difference, unless you’re flying an airliner (which eliminates a source of oxygen in a crash, and eliminates water condensing in the tires at frigid high altitudes) or a race car (where there’s a need to control tire pressures precisely).

I have the green caps, big deal not something for me to worry about. Didn’t someone come on here not to long ago wondering if they could add plain air to tires with nitrogen in them?
Thank you I was just curious like I said I had heard about using it but have never knew any one who has used it.
All airplane tires use nitrogen. If they used regular compressed air, the tires would go flat when it gets up to flying height and the temperature drops to -60F. The idea is that nitrogen does not expand or contract like compressed air. Tires get hot on the highway especially on a 100+ day. This means the pressure increases as the mixed gases expand.
I personally cant see the benefit on my personal car if they charge me $10/ tire for gas that cost about $0.02. The tires I buy are only about $50 each so to break even the tires would need to last 20% longer. That simply is not going to happen. On the other hand if I have $300 semi tires, a $10 expense would only need to increase the life 3%. That might happen.
Some race car drivers will use nitrogen in their tires because it is more predictable and constant. When you do huge burnouts at the drag strip the tires heat up significantly.

This is 100% BS! Air and nitrogen expand and contract EXACTLY THE SAME. Sorry, you are exactly wrong.
It’s a gimmick. I suspect it originated with some marketing whiz seeing that a race category used compressed nitrogen rather than compressed air and thought “wow! Perhaps we can sell it!”.
Truth is, race teams use nitrogen for safety. In the event of a fire in the pits, compressed air will feed it, while compressed nitrogen will smother it.

You left out the bit about it being a dry gas. As a purified gas, it doesn’t have water vapor mixed in. Race cars rely on accurate pressures in the tires for performance. A dry gas will be more stable across temperature that the tire experiences and therefore more stable pressure…

Green is the color used on labels in the compressed gas industry to indicate nitrogen. It saves time when looking for gas bottles if the labels are color coded. Color coding also makes it more difficult to pick the wrong bottle off the rack when using it.
The dealer had already put nitrogen in my tires when new. Yes green caps. But with sale prices, incentives, discount for using their finance department didn’t affect bottom line. But I wouldn’t ask for it. Ordered chrome caps with nice Blue Ovals to replace the green.
And no, I did not get ripped off by their finance department.
I got green caps last set of tires, my regular shop had the lowest prices, even after tire rack calculations, They do my oil changes, so I imagine they put nitrogen back in if needed, I always think people might look at my car in a parking lot and go “SUCKER” fell for that did ya.
How about helium to reduce unstrung weight?..

Helium would get through rubber pretty quick.
Sorry, my tablet doesn’t have the optional satire font.
Oh, I figured you were joking.
Pretty sure I have a green cap on my old wheelbarrow tire. But it indicates that the tire is loaded with puncture sealing slime not nitrogen…

Helium atoms are 1/16 the size of oxygen atoms. The tires wouldn’t hold it very long.
Good ol’ ambient air is the best fill. And it’s FREE!!!
I wish that air for tires was free. Any time I stop for gas on a trip and need air, I have to feed quarters to the air pump. Even at home it isn’t free since I had to buy my own pump. Real cheap, as much as I’ve used it, but still not free.
I guess we can keep this going.
For a happy car use N2O
Can I fill up at the dentist?
