Generally speaking, each tire will have a wear mark. If the tire wear reaches the position of the wear mark, it means that the depth of the tread groove is less than 1.6 mm at this time. In order to ensure driving safety, it is necessary to replace the new tire as soon as possible.

 

After all, once the depth of the tread groove on the tire is less than 1.6 mm, it is not only a problem of performance degradation, but also a potential safety hazard. Maybe you have no idea about 1.6mm. The more common way is to take out a one-yuan coin and insert it into the tread groove along the top of the national emblem, because the distance between the edge of the coin and the top of the national emblem is between 1 and 2 mm. You can see the entire national emblem, which means that the tread pattern has been worn out, and you need to go to the repair shop for tire replacement.
