How to Use a Tire Pressure Gauge
A tire pressure gauge is designed to check the air pressure inside the tires on a vehicle. Correct tire pressure is essential for correct vehicle operation and can improve mileage and performance as well. A tire gauge is constructed with a small diaphragm that is attached to a measurement device. The style of gauge can vary from digital to internal slide. A tire gauge is accurate to +/- 3 PSI, however it is possible to buy more advanced models that are capable of determining the pressure to as closely as +/- 1 PSI.
