After communicating with the car owners around me, I found out that everyone is righttireThe attention is not high, and basically they are using the original vehicletire. Regarding the question of when to replace the tires, many car owners have expressed that "as long as the tires are not broken or cracked, they can be used as long as they can be used, and they can be replaced if they are not."Tires are equivalent tocar"Shoes", the condition of which is directly related to the driving safety of the car. In this article, let’s take a look at when car tires need to be replaced.
● Pay attention to the "Signal"
Although the tires will not actively say "I can't hold it anymore" to the car owner, the car owner can rely on his own observation and touch to judge whether the tire has reached the level that it needs to be replaced.
1. Tread wear is close to the wear mark
Any brand of tires will have a wear mark on the bottom of the tread groove. The height of the wear mark on general car tires is 1.6 mm (this height is also the legal minimum groove depth of the tire), and the height of the wear mark on truck tires is 2.4 mm.
Some car owners think that as long as the tire is not broken, even if the tire pattern is about to be polished, the old tire is actually very dangerous: when it encounters a slippery road, the tread pattern cannot completely drain the water under the tire. , It is easy to cause the vehicle to lose control.
2. Damaged tires such as cracks or bulges
In the process of daily use of the car, the tire may be pierced by foreign objects or accidentally hit the road teeth, which will cause the tire to be damaged. Tyre damage includes cracks in the tread, bulging of the tread, missing tread rubber, severe sidewall wear, and multiple punctures of the tire by foreign bodies. Especially the bulge, the tire is in danger of bursting at any time. As long as these tires are found to be damaged, the car owner should go to a professional tire shop to check the tires of their car as soon as possible and replace them in time.
2. Avoid hitting the shoulder and falling into potholes
Some car owners have more aggressive parking methods. They like to let the car ride on the shoulder of the road. When the vehicle rides on the shoulder of the road, the tire will be squeezed, which will easily cause the cord on the side of the tire to break and cause the tire to bulge.
Potholes on the road should also be avoided. When the tire runs over the pothole, the tire will also be squeezed. The larger the pothole and the higher the speed, the more squeezed the tires will be, which will also cause the tires to bulge.
3. Avoid rubbing the tire wall
In many cases, the tire wall rubbing is caused inadvertently when the vehicle is pulled over. It may be the owner's poor sense of the car, or the owner's driving. The side of the tire is a weak part of the tire. If it is worn seriously, it will also cause the tire to bulge and bring the hidden danger of tire blowout. Therefore, car owners should pay more attention to the distance between the vehicle and the shoulder of the road when pulling over to avoid rubbing against the tire wall.
4. Maintain proper tire pressure
Appropriate tire pressure can ensure uniform tire contact area and reduce unnecessary wear. Therefore, car owners should develop the habit of checking tire pressure regularly and keep abreast of the tire pressure status. You can check the tire pressure at a professional repair shop, or you can buy a tire pressure meter to test it yourself. For the tire pressure standard, please refer to the tire pressure label of the vehicle.
5. Don't lower tire pressure in summer
Many car owners mistakenly believe that in summer, the temperature is high and lowering the tire pressure can prevent tire blowouts. In this way, the contact surface between the tire and the ground will increase, the friction will increase, and the tire wear will be accelerated, and it will cause the tire temperature to rise faster and more likely to puncture. Therefore, it is still necessary to maintain normal tire pressure in summer.
6. Interchange four tires according to tire wear
As the load of the front axle and the rear axle of the car are not the same, in order to make the wear of the four tires equal and prolong the service life, we recommend that the owner exchange the positions of the four tires every 8000 or 10000 kilometers. The owner can also decide whether to change the positions of the four tires based on the tire wear.
What are the symmetrical, asymmetrical, and directional patterns of tires?
Symmetrical pattern(Picture 1) It is based on the groove in the center of the tread, and the patterns on the left and right are the same;Asymmetric pattern(Picture 2) The pattern of the tire tread is not symmetrical;Directional pattern(Figure 3) is a pattern that requires the direction of tire rotation.

Summarize:The role of tires for car safety is very important, and car owners should devote more attention to tire maintenance and inspection. If you find a “signal” that a tire needs to be replaced, the car owner must pay attention to it, spend money when it is time to spend, and replace the problematic tire decisively-you know, just saving money on tires is equivalent to adding weight to potential safety hazards .
[Note]Do not change the tires at all times, the tires are not as fragile as you think
[Posture]Engine/Tire/car windscreenThere is such a string of numbers on it, which is quite long!
[Note]The tires are punctured. These conditions must not be repaired, but only replaced!
[Posture]Is the tire narrower or wider?Many people are confused
