Tires are another critical component on the race car.
A blowout at high speed can be incredibly dangerous. They have to remain stable at very high temperatures and speeds, provide incredible traction and be changed very quickly. Nitrogen Instead of Air Most of the teams remove the air from the tires and replace it with nitrogen. Compressed nitrogen contains less moisture than compressed air. When the tire heats up, moisture in the tire vaporizes and expands, causing the pressure inside the tire to increase.
