How to Determine Tire Pressure on Sprint Cars

Video Transcript

"This is a tire pressure gauge. You check the pressure of the tires and to change tire pressures every time you come in, depending on track conditions, the track continues to change every single time you go out there. This is really easy to use, its got a number gauge on it. You just hook it up into this valve and it will show you a read. You just read the ticks and you adjust the higher pressure with this little button and it just lets air out of the tire. Its really easy to use. You can put air pressure in the tires by an air tank that is pressurized, the same thing but this is putting pressure in the tire instead of out. It depends on how much the track is changing but most times its only one or two PSI your taking in or out of the tire."
