which air can be used to fill tyres

Answer 1

Answer 2

Hey Mate..

Nitrogen gas

Hydrogen and helium would leak out pretty fast….. Usually Compressed air is used to fill car tires. Some race cars and performance vehicles use nitrogen gas as they are light and maintain the pressure for a longer period of time when compared to air.
