How to judge the service life

Generally speaking, the life of a tire in normal use is 4-5 years. After 5 years, it is best to replace it even if the tire pattern is very small, because the rubber on the tread will age over time, and there will be many small cracks. It is the cause of a flat tire.

For example, most of the aging parts of the tread begin to appear from the edge parts such as the sidewall or the shoulder. The long time in the sun and rain will cause small loops on the rubber surface, which shows that the load capacity and quality of the tire at this time have been It starts to decline, and it is best to replace it early to reduce the risk of puncture.

In addition to aging, tires will wear out naturally. Therefore, the tires of the factory will be marked with wear marks on the sidewalls before leaving the factory to show the real-time wear of the tires. At the same time, we can also use calipers to measure tires without signs of wear. Generally, tires with a groove depth of less than 1.6 mm can no longer be used, because the drainage and puncture resistance of the tire will be greatly reduced at this time. In addition, if a tire has been repaired three or four times, then we recommend that you better replace it with a non-driving wheel or a rear wheel to reduce the risk of puncture.

Of course, the life of a tire is closely related to whether it is used normally. First, we must ensure that the tires are always under normal tire pressure. Too low or too high tire pressure will bury hidden dangers for tire safety. It must be reminded that don't believe your eyes to see it, because most cars nowadays are equipped with low-pressure radial tires without inner tubes. Sometimes they may feel a little dent from the outside, but this doesn't mean you have to lose air. Professional tire pressure instrument is the only way to detect tire pressure. In addition, when detecting tire pressure, it must be in a cold tire state. If it is a hot tire measurement, the measured value must be reduced by 0.3PA to be accurate.

The service life of automobile tires is directly related to the personal safety of our drivers and passengers. I believe everyone knows how high the risk factor of a flat tire is. In addition to a puncture, if the tire is severely worn, it will also cause the car to have poor grip and easy to slip. In addition, when it rains or snows at low temperatures, road icing will seriously threaten our personal safety, so drivers should pay attention.
