Tire Pressure Gauge

22 May 2024

Types of tire pressure gauges

Pointer tire pressure gauge:

A traditional tire pressure gauge with a mechanical pointer and dial.

The interaction between an internal spring and air pressure drives the pointer to move and display the pressure reading.

Digital tire pressure gauge:

Equipped with LCD display to directly display digital readings.

Usually easier to read and more accurate.

Pen type tire pressure gauge:

Shaped like a pen, easy to carry.

There is a scale inside, which will extend when pressure is applied to display the tire pressure.

Integrated tire pressure gauge:

Some tire pressure gauges are integrated into the car's air pump, making it easy to measure tire pressure while inflating.

How to use tire pressure gauge


Make sure the tires are measured in a cold state (i.e. after the vehicle has been parked for at least 3 hours or driven no more than 1.6 kilometers).

Measurement steps:

Remove the cap from the tire valve.

Press the measuring port of the tire pressure gauge tightly against the valve to make sure there is no air leakage.

Read the reading on the tire pressure gauge, the analog tire pressure gauge reads the pointer position on the dial, and the digital tire pressure gauge reads the value on the display screen directly.

Adjust pressure:

If the pressure is too low, use an air pump to inflate the tire to the recommended pressure.

If the pressure is too high, press the valve core slightly to release the air until the correct pressure is reached.


After completing the adjustment, use the tire pressure gauge again to make sure the tire pressure is within the recommended range.

The importance of tire pressure gauge

Improve driving safety:

Correct tire pressure can effectively prevent tire blowouts and ensure driving safety.

Optimize fuel efficiency:

Proper tire pressure can reduce tire rolling resistance, improve fuel efficiency, and reduce fuel consumption.

Extend tire life:

Maintaining correct tire pressure can reduce abnormal tire wear and extend its service life.

Improve driving experience:

Proper tire pressure can improve the vehicle's handling performance and comfort.

Things to note when using tire pressure gauges

Periodic inspection:

It is recommended to check tire pressure at least once a month, especially before driving long distances or carrying heavy loads.

Keep dry:

The tire pressure gauge should be stored in a dry place to avoid moisture affecting the measurement accuracy.

Choose a high-quality tire pressure gauge:

High-quality tire pressure gauges have higher measurement accuracy and longer service life.


The tire pressure gauge is an important tool in vehicle maintenance. By regularly checking and adjusting tire pressure, driving safety, fuel efficiency and tire service life can be significantly improved. Whether it's a family car or a commercial vehicle, maintaining proper tire pressure is key to ensuring good vehicle performance and safe driving.
