A tire pressure gauge is a device used to measure the air pressure inside a tire. It is important to maintain the correct tire pressure for safety and performance reasons. Underinflated tires can lead to decreased fuel efficiency, poor handling, and increased wear and tear on the tire. Overinflated tires can be dangerous, as they can cause the tire to burst.
There are two main types of tire pressure gauges: analog and digital. Analog gauges use a mechanical dial to indicate the pressure, while digital gauges display the pressure on a digital readout. Digital gauges are generally more accurate and easier to read than analog gauges.
