Short Answer...yes. Nitrogen doesnt expand with heat. Air does. They are mixable, but it's best to just stick with one or the other.
The air in the atmosphere is approx 78% nitrogen anyway. All gases behave the same according to the gas laws. If nitrogen did not expand with heat how could a hot air balloon get off the ground?
The benefits of filling tires with nitrogen are,
1 the air has had all the moisture removed ( no rim corrosion)
2 Nitrogen doesn't expand as much when heated (less pressure variance due to temp)
3 Nitrogen is a larger molecule so it doesn't leak as easily.
Mixing nitrogen and regular air in tires will dilute the benefits of having pure nitrogen-filled tires, such as more stable tire pressure and reduced oxidation of the tire components. It may still provide some benefits over using regular air alone, but the advantages won't be as pronounced.
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.
Any tire inflated with a gas (air or nitrogen ) is a pneumatic tire.

Sure. There is no logical reason not to mix it. Regular air is mostly nitrogen anyways.
The two will mix.
Air is 78% nitrogen, and most tyres are inflated with air, so mixing pure nitrogen with air would not be a problem.

Air or nitrogen is used to inflate tires
nitrous oxide? <><><><> Air you are breathing right this second is a mix of nitrogen (79%) and oxygen (21%)
The air that you breathe is 79.8% nitrogen. By using 100% nitrogen you exclude oxygen from inside your tire. Less oxygen, less corrosion of the tire and rim. In short it makes no difference if you have nitogen or air. Its just a marketing scam to charge you an extra $8.00 per tire for something that makes no difference in tire performance.
78% of the air we breathe is nitrogen. 21% is oxygen, and the other 1% is a mix of other gasses.
