    Generally speaking, the normal life of the tire is 4 to 5 years. After 5 years, even if the wear of the tread is small, try to replace it, because the rubber of the tread will age due to the long time, and many small cracks are Caused by the puncture.

    However, the relevant departments of the state have not yet made special provisions on the shelf life of tires, because the service life of tires will vary according to the different rubber formulas of the tires, the environment of the car and the driving habits. Therefore, this requires us to drive more and keep more heart, and tire aging is also a sign. For example, the aging part of the tread is mostly from the edge of the bead or shoulder. The long-term sun and rain will cause small cracks in the rubber surface. These cracks indicate the bearing capacity and quality of the tire. Has begun to decline, in order to reduce the risk of puncture tires as much as possible to replace in advance.
    In addition to aging, the tires are also naturally worn. Therefore, the factory tires will be marked with a wear limit on the sidewall before leaving the factory to indicate the real-time wear of the tire. For tires without wear marks, we can also use calipers to measure. Generally, tires with a groove depth of less than 1.6 mm can no longer be used, because the drainage performance and the anti-strength performance of the tires will be greatly reduced. In addition, if a tire has been repaired three or four times, we recommend that you try to change the tire to a non-drive wheel or rear wheel to reduce the risk of puncture.
    Of course, the life of the tire is also related to the normal use of the peacetime. First of all, we must ensure that the tires are always under normal tire pressure, too low or too high tire pressure will give the tire safety hidden danger. Need to remind everyone is not to believe what the eyes see, because most cars are now equipped with low-pressure radial tires without tubes, sometimes it will feel a little embarrassed from the outside, but it does not mean that it will be a loss, professional tire pressure The instrument is the method to detect the tire pressure. In addition, when testing the tire pressure, it must be in the cold tire state. If it is the hot tire measurement, it is accurate to reduce the measured value by 0.3PA.
