How to read tire pressure gauge
As the number of cars continues to increase, the issue of safe driving has attracted increasing attention. Recently, tire pressure monitoring has become one of the hot topics, especially in hot summer weather, abnormal tire pressure can easily cause tire blowout accidents. This article will introduce in detail how to use the tire pressure gauge to help car owners correctly monitor tire pressure and ensure driving safety.
1. Basic types of tire pressure gauges
A tire pressure gauge is a tool for measuring tire pressure. According to its working principle and display method, it is mainly divided into the following types:
| Type | Features | Applicable scenarios |
|---|---|---|
| Mechanical tire pressure gauge | Displays air pressure through pointer, no batteries required, strong durability | Household vehicles, repair shops |
| Digital tire pressure gauge | LCD screen display, accurate reading, simple operation | High-end vehicles and precise measurement requirements |
| Tire Pressure Monitoring System (TPMS) | Real-time monitoring of tire pressure, abnormal alarm | Standard on modern vehicles |
2. How to read the tire pressure gauge correctly
Whether it is a mechanical or digital tire pressure gauge, reading the data correctly is the key to ensuring normal tire pressure. Here are the specific steps:
1.Check the tire pressure gauge unit: The display unit of the tire pressure gauge may be PSI (pounds per square inch), Bar (Bar) or kPa (Kilopascal). The standard tire pressure units of different vehicles may be different and need to be confirmed according to the vehicle manual.
2.Preparation before measurement: Make sure the tires are in a cooling state (the vehicle has been stopped for at least 3 hours) to avoid high temperatures affecting the readings.
3.Connect tire pressure gauge: Align the measuring head of the tire pressure gauge with the tire valve and press firmly to ensure a seal.
4.Read data:
| Tire pressure gauge type | Reading method |
|---|---|
| Mechanical | Observe the scale value pointed by the pointer |
| digital | Directly view the value displayed on the LCD screen |
5.Compare standard value: Check whether the current tire pressure is within the recommended range according to the vehicle manual or the label on the door frame.
3. How to deal with abnormal tire pressure
If the tire pressure gauge displays abnormal values, the following measures need to be taken promptly:
| question | Possible reasons | Solution |
|---|---|---|
| Tire pressure is too low | Air leakage, temperature changes | Add air pressure and check whether the nails are inserted |
| Tire pressure is too high | Overinflation, high temperature expansion | Deflate appropriately to standard value |
| Tire pressure is unstable | Sensor failure | Repair or replace tire pressure monitoring system |
4. Precautions for tire pressure monitoring
1.Regular inspection: It is recommended to check tire pressure at least once a month, and be sure to confirm before driving long distances.
2.Seasonal adjustment: Tire pressure can be slightly higher in winter, but excessive tire pressure needs to be prevented in summer.
3.Spare tire inspection: The tire pressure of the spare tire is usually higher than the normal value and needs to be confirmed separately.
4.Equipment calibration: Digital tire pressure gauges need to be calibrated regularly to ensure accurate readings.
5. Recommended brands of popular tire pressure gauges
According to recent e-commerce platform sales and user reviews, the following brands of tire pressure gauges have outstanding performance:
| Brand | Model | Features | price range |
|---|---|---|---|
| Michelin | 12264 | Mechanical, durable and precise | 50-80 yuan |
| iron general | T6 | Digital display, backlight function | 100-150 yuan |
| 70 miles | TPMS | Wireless real-time monitoring | 300-500 yuan |
Through the above content, I believe you have mastered the use of tire pressure gauges. Properly monitoring tire pressure not only improves driving safety, but also extends tire life. It is recommended that car owners develop the habit of regular inspections to ensure safe driving.
