Solution:
Nitrogen
is used for filling aeroplane tyres.
Nitrogen is an incombustible gas so it does not flame to the fuel.

Nitrogen is least reactive hence it is not corrosive.
It does not cause rust and corrosion on steel and aluminum.
Nitrogen does not wear the tyre like air and it reduces pressure loss in tyre
