What tool do you use to measure the tire pressure and how do you think it works?

To measure tire pressure, I use a tire pressure gauge, which can be either digital or analog. The gauge works by connecting it to the valve stem of the tire, allowing air to flow into a calibrated chamber. This movement of air pushes a piston or activates a sensor, which displays the pressure reading in PSI (pounds per square inch). Accurate measurements are crucial for maintaining proper tire health and vehicle safety.
