Everyone knows that cars are consumables，Many places need to be maintained frequently，and many parts need to be replaced regularly，and the most component of the car on the car is the tire that contacted the ground with the ground。But how long can a tire take? Most car owners can't say clearly，This should be based on driving mileage and road conditions。But today we can learn some techniques that need to be replaced，for timely replacement，Avoid accidents。

a，See if there is any obvious trauma on the surface of the tire。Tire surface wear marks are unavoidable，But some serious trauma still need to pay special attention。For example, less block，cracks, etc.。Although these trauma may not affect normal work at the time，But it is likely to cause air leakage or even tire。So when this severe trauma appears on the surface of the tire，It should be replaced。

2，See the degree of tire wear。Even if it is not severely traumatized，Normal wear is also limited。my country stipulates that when the thickness of the tire pattern is worn to 1.6mm，Tire must be replaced。General home vehicles are driving about 60,000 kilometers under normal Seabetroad conditions. Tire should be changed，You can also measure the thickness of the pattern with tools，Too count in my heart。

3，Pay attention to the production date。Although the tire uses consumables，But even if you don't use it，The tire also has a shelf life。Because it takes a long time, it will make the rubber aging，This will greatly increase the possibility of explosive tire，Very dangerous。General tire life is also four or five years，So remember the production date of your own tire，and do not use tires produced by too long before replacing the tire。
