Aircraft tires are usually inflated with nitrogen to minimize expansion and contraction from extreme changes in ambient temperature and pressure experienced during flight. [4] Dry nitrogen expands at the same rate as other dry atmospheric gases (normal air is about 80% nitrogen), but common compressed air sources may contain moisture, which ...

Analytical chemistry: Nitrogen generators are required for various forms of analytical chemistry such as liquid chromatography–mass spectrometry and gas chromatography where a stable and continuous supply of nitrogen is necessary. Aircraft & motor vehicle tires: Although air is 78% nitrogen, most aircraft tires are filled with pure nitrogen ...
In a theoretically perfect situation with weightless spheres, a "vacuum balloon" would have 7% more net lifting force than a hydrogen-filled balloon, and 16% more net lifting force than a helium-filled one. However, because the walls of the balloon must remain rigid without imploding, the balloon is impractical to construct with any known material.
Airless tires are attractive to cyclists, as bicycle tires are much more vulnerable to punctures than motor vehicle tires. The drawbacks to airless tires depend on the use. Heavy equipment operators who use machinery with solid tires may become fatigued. Any airless tire will be heavier than the rubber tire it is meant to replace.
These techniques prevent the compounds from reacting with components of air, usually water and oxygen; less commonly carbon dioxide and nitrogen. A common theme among these techniques is the use of a fine (10 0 –10 −3 Torr) or high (10 −3 –10 −6 Torr) vacuum to remove air, and the use of an inert gas: preferably argon, but often nitrogen.
Make sure the vehicle and the headlights are clear and not covered with ice or snow, make sure your tires have adequate tread and travel at a safe speed especially when roads are icy."
