How to check tire pressure?

During driving, tire pressure will have an important impact on us. Once there is a problem with tire pressure, it will have a negative impact on our driving and the vehicle. So we need to understand the importance of tire pressure and how to check whether the tire pressure is at a normal level.

Importance of Tire Pressure

Tire pressure is very important for vehicles, mainly reflected in the following points:

1. Safety guarantee: Too high or too low tire pressure may lead to reduced tire performance and affect driving safety. Proper tire pressure can ensure that the tire maintains good contact with the road, provide stable grip and braking effect, and reduce the risk of tire blowout.

2. Performance: Correct tire pressure helps improve tire performance, including power and smoothness. Proper tire pressure can reduce tire rolling resistance, improve fuel efficiency, reduce tire wear and extend service life.

3. Comfort: Too low tire pressure may cause tire overheating, causing the vehicle to vibrate when driving, affecting comfort. Proper tire pressure can reduce these vibrations and improve driving and riding comfort.

4. Load capacity: Tire pressure is a sign of the vehicle's load capacity and directly affects the vehicle's load-bearing capacity. Proper tire pressure can ensure that the vehicle maintains good stability and safety under different loads.

5. Handling stability: Tire pressure also affects the vehicle's handling stability. Proper tire pressure helps improve the stability of the vehicle when driving at high speeds and turning.

In addition, regularly checking tire pressure and keeping it within the recommended range can not only ensure the performance and service life of the tire, but also save fuel consumption, reduce carbon dioxide emissions, reduce the accident rate, and ensure driving safety.

In summary, the importance of tire pressure lies in that it is directly related to the performance, safety and economy of the vehicle. Proper tire pressure is essential to ensure the performance and driving safety of the vehicle.

How to check tire pressure?

When checking tire pressure, we should use a combination of visual inspection, manual inspection (tire pressure gauge) and monitoring system to check whether the tire pressure is normal.

Visual inspection:

Visual inspection of tire pressure is a simple method to determine whether the tire pressure is normal by observing the contact between the tire and the ground.

1. Observe the number of tire treads contacting the ground: When the tire is cooled (it must be cooled), observe the contact between the tire and the ground. Under normal circumstances, the number of tire treads contacting the ground should be 4 to 5. If the number of treads contacting the ground is more than 6, it means that the tire pressure may be low; if it is less than 4, the tire pressure may be high.

2. Check tire wear: Too high tire pressure will cause severe wear in the center of the tire, while too low tire pressure will cause severe wear on the shoulder. You can judge whether the tire pressure is normal by observing the wear of the tire.

3. Observe the appearance of the tire: When the tire pressure is too high, the tread may be curved; when the tire pressure is too low, cracks may appear on the sidewall. By observing the appearance of the tire, some abnormal phenomena can be found.

However, it should be noted that visual inspection of tire pressure is only a rough method. Although this method is simple, it cannot replace a professional tire pressure gauge. If the tire pressure is found to be abnormal, it is recommended to use a tire pressure gauge for accurate measurement and adjust it according to the tire pressure value recommended by the vehicle manufacturer.

Monitoring system inspection:

The automobile tire pressure monitoring system (TPMS) is an electronic safety system used to monitor the tire pressure and temperature of the automobile in real time. It detects the tire pressure and temperature through sensors installed in the tires and sends this information to the vehicle's receiver module. If the tire pressure is too low or too high, the system will alert the driver through the warning light on the dashboard or the information display.

The main functions of TPMS include:

1. Real-time monitoring: During the driving process of the vehicle, TPMS can monitor the pressure and temperature of each tire in real time.

2. Early warning: When the tire pressure is too high, too low or the temperature is too high, the system will issue an early warning to the driver to ensure driving safety.

3. Classification: TPMS is mainly divided into indirect and direct types. The indirect tire pressure monitoring system monitors the tire pressure by comparing the speed difference between the tires, while the direct tire pressure monitoring system uses the pressure sensor installed in the tire to directly measure the tire pressure.

4. Calibration: After changing the tire or adjusting the tire pressure, it may be necessary to start the tire pressure monitoring system calibration to ensure that the system can accurately monitor the new tire pressure value.

5. System failure: If the TPMS system fails, the warning light on the dashboard or the information display will display the corresponding fault information to remind the driver to repair it in time. Have you ever noticed the flashing signal light on the display? That is the monitoring system alerting you.

TPMS is of great significance to improving driving safety and preventing tire failures. With the development of technology, modern TPMS systems also have more intelligent functions, such as remote monitoring, etc., to provide drivers with more comprehensive safety protection.

Tire pressure gauge check:

The tire pressure gauge is a tool for measuring the tire pressure of a vehicle. You can check whether the tire pressure is within the normal range through the dashboard of the tire pressure gauge.Can be used with tire air pump.

1. Prepare the tire pressure gauge: Make sure the tire pressure gauge is in good condition. For mechanical tire pressure gauges, check whether the pointer is zero.

2. Find the standard tire pressure value: Find the standard tire pressure value on the vehicle, usually marked with a sticker on the driver's door frame or the side of the door, or check it in the vehicle manual.

3. Choose the right time: Tire pressure measurement should be performed when the tire is cool, that is, after the vehicle has been parked for at least 3 hours

4. Measure tire pressure: Unscrew the cap on the tire valve.

For mechanical tire pressure gauges, align the measuring head of the tire pressure gauge with the tire valve and press it in hard to ensure sealing.

Observe the reading on the tire pressure gauge. For pointer tire pressure gauges, the reading should be indicated on the dial; for digital tire pressure gauges, the reading will be shown on the display.

5. Compare readings: Compare the measured tire pressure value with the standard value recommended by the manufacturer. If the tire pressure is too high, you can use the deflation function on the tire pressure gauge to release the air appropriately; if the tire pressure is too low, you need to use an inflator to inflate the tire (you can use a tire pump).

6. Cover the valve cap: After the measurement is completed, re-cover the valve cap.

Repeat steps: Repeat the above steps for other tires to ensure that all tire pressures meet the requirements.

Through the above steps, you can effectively check and adjust the tire pressure to ensure the safety and comfort of vehicle driving.
