Nitrogen why because,
Being an inert gas, it cannot catch fire or explode or aid combustion.
Tyres inflated with nitrogen run between 10 and 15% cooler.
Tyres inflated with air run hotter than those inflated with nitrogen. Nitrogen disperses heat quicker than air. Tyres run cooler and tyre life is extended by up to 20%. Tyres inflated with nitrogen do not lose pressure as quickly as those filled with air.
Even Formula 1 Cars do use Tyres filled with Nitrogen

Nitrogen is preferred over air in tyres.
A combination of Nitrogen and Helium is also used
Upto 1940 and during World War 1,
Hydrogen was also used to fill tyres. Later it was banned in 1954 as Hydrogen is a highly combustible gas

I went to several web sites and deduced the following: 1. Aircraft tires get much hotter during taxi, takeoff and landing. They run at much higher speeds during takeoff and landings (140 mph and higher) and support much, much heavier weight. 2. This heat causes moisture in the air (inside the tire) to expand causing tire pressures to increase. 3. Nitrogen doesn't have the high moisture content. 4. Nitrogen doesn't oxidize or react to aluminum wheel parts 5. Nitrogen doesn't degrade rubber 6. Aircraft operate at much higher altitudes were air pressure differentials are greater. Moisture in air can condense out with these pressure changes. With that being said, why do I not use nitrogen in my car tires? 1. Too expensive. Some places charge$30 for a nitrogen purge and fill up 2. My tire treads wear out after about 50,000 miles long before the rubber degrades due to the use of plain air. 3. The $30 price negates any savings on fuel mileage, tire life or other "costly" issues. 4. My tires always have about 78% nitrogen inside them anyway. Air is 78% nitrogen. 5. Using nitrogen adds to the cost of fixing a flat tire because of the lost nitrogen. Nitrogen will not prevent a flat tire due to a puncture from a nail. One experiment I read about (for the family car) was this. The front tires were filled with air and the rear tires were filled with nitrogen. After 6 months, tire pressures were relatively the same.

Aeroplane tyres are filled with Nitrogen for avoiding fire accidents.
If filled with air, it contains oxygen and may help fire.

they're filled with nitrogen. Nitrogen filled tires are supposed to get 3-5 percent better fuel mileage. ...

Air (air has nitrogen in it) So Nitrogen too.

I have also heard that some miltary aircraft planning on trying airless tyres that would be much more reliable and superior in all kind of situations.

neither of them is used
the gas used is helium
[He] is used bcoz
it is a lighter gas
it is inert
it can't catch fire
it reduces the friction n avoids the explosion of tyres that might be caused due to the great force exerted by the ground
