How to judge the service life and the degree of wear of the tire

- Mar 07, 2018 -

Generally speaking, the service life of the normal tire is 4 to 5 years, and after 5 years, even if the tire wear is very small, it is best to replace it, because the tire rubber will be aging because of the long time, and many small cracks are the inducement of tire burst.


However, the relevant departments of the state have not yet specified the shelf-life of the tire for the time being, because the service life of the tire varies according to the difference of tire rubber formulation, vehicle environment and driving habits. So it is necessary for us to drive more heart, and the aging of the tires is also a sign. For example, the tread part of aging mostly began to emerge from the bead or shoulder edge parts such as small crack, long-term sun and rain will let the rubber surface appear in circles, these cracks at this time that the bearing capacity of the tire and quality have already started to decline, in order to reduce the risk of tire replacement ahead of the best.


In addition to aging, the tires are also naturally worn.  Therefore, the wear limit of the tire is marked on the side of the tire before the factory is out of the factory, so as to indicate the real time wear of this tire. For tire with no wear marks, we can also measure with calipers. Generally, the tire with a groove depth less than 1.6 millimeters can no longer continue to use, because the drainage performance and anti tie performance of the tire will drop dramatically. Besides, if a tyre has been repaired three or four times, we suggest that you change the tire to the non driving wheel or the rear wheel, so as to reduce the risk of tire burst.


Of course, the life of the tire is also related to the normal use of normal. First of all, we want to ensure that the tire is always under normal tire pressure, too low or too high tire pressure will bury the tire safety. Need to remind you that don't believe what your eyes see, because now most of the car assembly is a tubeless radial tire pressure, sometimes from the outside will feel a little flat, but it does not mean a loss of gas, professional tire pressure instrument is the only way to test the tire pressure. In addition, the test of tire pressure must be cold tire condition, if it is a hot tire measurement to reduce the value of the measured value of 0.3PA to be accurate.
