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.
Sure. There is no logical reason not to mix it. Regular air is mostly nitrogen anyways.
Air is 78% nitrogen, and most tyres are inflated with air, so mixing pure nitrogen with air would not be a problem.
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.
Yes, nitrogen is more stable than air in tires.
air
Air. Nitrogen in the tires.
Yes, you can use nitrogen or plain air.
Nitrogen , check out this site, http://www.getnitrogen.org/ Typically, plain air. Nitrogen is used in high-performance racing tires and in large aircraft tires.
There are no 'types' of air. Air is all just air. - Some people do use nitrogen in tires - that is not air.
Some people think that tires will last longer if filled with nitrogen instead of air. Air contains about 21 percent oxygen, which is known to gradually weaken tires through the process of oxidation. Nitrogen has no known bad effects on tires.
Nitrogen It's volume changes less than air as the tires temperature changes.
No. Improper pressure will.
