This is a youtube video about karting and tire pressure. It is an informational video explaining how to get the perfect tire pressure. Getting the perfect tire pressure is important because when the tire heats up, the pressure gets high which causes the tires to lose grip. If you set the pressure to high, the pressure will rise and you will lose tire grip early in the race causing you to lose time. If you set it just right, your tires will have grip the whole race. This video will help because of how important it is to have the perfect tire pressure.
