Using nitrogen in car tires yields better fuel efficiency and longer tire life.
There are no "tire laws" for used car dealers.
Air or nitrogen is used to inflate tires
Nitrogen is used in many aircraft tires.

Nitrogen
Nitrogen is used in tires because it is less permeable than air, reducing the rate at which the tire loses pressure. This can result in improved fuel efficiency, longer tire life, and better tire performance, especially in extreme temperatures. Additionally, nitrogen is inert which means it does not react with the materials in the tire, reducing oxidation and corrosion.
It's nitrogen.
Compressed air or compressed nitrogen.
I think it is Nitrogen. The normal air mixture pumped into regular road cars is not efficient at high speeds and will lose pressure easily. If that happens there could be catastrophic consequence at high speed. That is why they use nitrogen If you pump nitrogen into the tires of your regular road car, you need not check tire pressure for 3 months.
If you have a nitrogen filled tire that is low you can put in regular compressed air to fill it up, but you will lose some of the benefit of the nitrogen. You should replace the green cap with a black one if you have filled the tire with regular air. 90% of cars on the road are just using regular compressed air, and not having a lot of problems. So I wouldn't worry too much about it.
Used tire changers are machines used by mechanics that help mount and dismount tires on cars, motorcycles and trucks. It has all the parts necessary to replace the tire from the wheel.
There are some disadvantages to nitrogen, especially in inflation. Two disadvantages include the expense of nitrogen, and the fact that more tire maintenance will be needed if nitrogen is used.
