Hello everyone, I'm Xiao Li. How do I tell when a tire needs to be replaced? Many people are not clear, resulting in being fooled into replacing the tires that can continue to be used safely, and as a result, a lot of unjust money has been spent. In fact, in many cases, we ourselves can fully judge the tires of our car to the end to replace the time, today Xiao Li came to share with you 3 kinds of situations that need to change tires, I hope that my explanation can help everyone. If you are interested in the content of car maintenance and car use, don't forget to pay attention to Ha.
In the first case, the tire exceeds its service life. Tires are rubber products after all, and they will have a service life like our oil. The oil is calculated according to the mileage, but the tire is not the same, it is calculated according to the service life of the vehicle. This is mainly because the normal use of the vehicle (idle will cause the tire to age in advance) In a certain service life, the more tires you run for the tires, the more frequent the mutual extrusion movement inside the rubber products, the less likely it is to age.
The general tire service life is 5 years, beyond this time it is recommended to change the tire. However, if you are temporarily tight on money, you can continue to use it in a short period of time, and then change it when you have money. It is best to replace it as soon as possible, because the indicators of all aspects of the tire that exceed the service life will gradually decline, and there is a risk of puncture when driving at high speeds. It's like a fully synthetic engine oil is obviously 10,000 kilometers to be replaced, but I often change it at 11,000 without pay, the reason is the same, it will not be scrapped immediately, but it cannot be used for a long time to change as soon as possible.
In the second case, the tire ages prematurely. The service life of the tire mentioned earlier is 5 years, but if your tire protection is not in place, it will cause the tire to age prematurely. For example, if the vehicle is idle for too long and the tires cannot be run for a long time, there will be a series of problems such as loss of gas and deformation. In these states, the tires have aged in advance, and they can no longer be used, otherwise they are prone to puncture accidents.
I remember once the company's car did not use the tire for a long time, I took the pump to fill it, and I didn't expect to burst the tire the next day. This is mainly because the tire is not used for a long time, the rubber inside can not squeeze the movement to cause the rubber to become hard and brittle, and after suddenly changing the state of the tire (such as being too full of gas from the gas loss) there will be a puncture of the tire due to the lack of plasticity of the rubber. In addition, long-term exposure to the sun will also cause tires to age in advance, and we must pay attention to these problems.
In the third case, the tire reaches the wear limit. After all, the tire is a friction part, and it constantly rubs against the ground when driving, so it also has a wear limit. There will be a triangular symbol on the tire wall, and a protruding area at the bottom of the groove on the countertop. If the tire wears out to these two marking points, it should be replaced as soon as possible, otherwise there will be a risk of puncture.
Many people do not know how to observe the wear limit of tires, Xiao Li teaches everyone a method, do not need to use any coin directly with the naked eye to judge. That is to directly observe the pattern surface of the tire, according to my experience as long as the pattern of the tire surface is flattened, or close to the flattening that is definitely beyond the wear limit, must be replaced as soon as possible. Otherwise, if you continue to use it, there will be a very big security risk.

Tires that wear to the limit
The above is Xiao Li to everyone to summarize the 3 situations on how to judge whether the tire needs to be replaced, I hope that my explanation can help everyone, if you think what I said is useful, don't forget to give me some praise, thank you.
