The importance of tires is self-evident as the only parts in contact with the ground during the driving of the car. Most car accidents at high speeds are related to tires. At the same time, tires are rubber products, and wear will inevitably occur over time. As time and mileage increase, tires will have shallow grooves, weakened grip, and longer braking distances, resulting in reduced safety. Some people may ask since tires are so prone to wear and important, how often should a car tire be changed?

In fact, how often a car tire is changed can be judged according to the wear mark of the tire. The general replacement cycle is roughly within 3-5 years or between 40,000 and 60,000 kilometers after the car has been driven. Of course, due to differences in driving habits and road conditions, there may be discrepancies. The mileage, time, and actual wear of the tires can be used to determine whether the tires need to be replaced. The auto accessories exhibition will tell you how often a car tire needs to change. The following is a detailed explanation for everyone.

1. Mainly depends on the tire wear mark.

Generally speaking, every tire will have this logo, and Goodyear tires will also have classic flying foot logos on the sidewalls, which are signs of tire wear. If the tire wear reaches the location 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 don’t have a concept of 1.6mm. The more usual 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.

2. It should also be determined based on the tire shelf life.

Some car owners bought their cars, but for various reasons, they kept their cars in the underground garage and rarely drove them out. Although the tires of such cars do not have much wear, they should still be careful when driving because the tires will also "expire".

There will be 4 digits on the tire sidewall to indicate the date of manufacture. The first two digits represent the week number, and the last two digits represent the year. For example, in 1617, means that the tire was produced in the 16th week of 2017. After knowing the production date, under normal circumstances, it only needs to add 5 years to the production date to infer the best service life of the tire.

3. It also needs to pay attention to the actual mileage.

Generally, the normal driving kilometers are about 40,000-60,000 kilometers. After these kilometers, the driving risk will be greatly increased. In a driving environment dominated by urban asphalt roads, since the driving environment is good, the upper limit of the number of kilometers traveled by tires can be appropriately referred to. In the case of non-paved roads and mountainous areas in the suburbs, the lower limit of the tire mileage should be used as the standard for car tire replacement.

4. It also pays attention to whether there is trauma on the tread, shoulders, sidewalls, etc.

For example, the tire surface has obvious cracks, bulges, deformation, and nails. Once the tire is deformed and bulged, it proves that the metal coil inside the tire has been deformed or broken. If you continue to drive, it is very likely that a tire burst may occur.

It is not difficult to find that how often a car tire is changed cannot be judged by a certain condition alone. It should be measured in combination with the degree of wear, service life, and mileage.

China tire trade show advises you: if you use the car frequently when the tire pattern has worn to the wear mark, or if you do not use the car frequently when the tire reaches the end of its service life, you need to replace the tire in these cases. When the tires appear to be cracked and bulged, they need to be replaced as soon as possible and should not be used. The most important thing is those car owners themselves have to develop the habit of regular maintenance of tires, so as to extend the service life of tires.
