because if you didnt they would be flat......... obviously
It's just regular air.
Nitrogen and oxygen = Air
Nitrogen mixed with normal air
80%nitrogen 20% oxygen........ which is the exact same gas as ambient air. you put AIR IN TIRES!!!
F1 tyres are filled with Nitrogen since it is a more stable gas than air
It is what fills the tires, in the form of air.
Examples of solid in a car include the metal body, rubber tires, and plastic components. Liquids in a car include engine oil, coolant, and windshield washer fluid. Gas in a car includes the fuel in the gas tank and the air in the tires.
When tires or balloons are filled with gas or air, they are said to be in an inflated state.
Street cars air (which is manily Oxygen, nitrogen), race cars nitrogen.
There's moisture in air. When you fill your tires with compressed air, the moisture goes in the tire too. Moisture then has potential to rust out the rim from the inside. They use other gas (nitrogen?) that doesn't have moisture. Usually garages will put green air valve caps on tires filled with gas.
F1 teams use Nitrogen to fill the tires because of its low dilatation compared to air, a small dilatation in a F1 tire will result in unbalancing the car.
