The tire is a key part of the car, but many consumers don't care about it. The quality of the tire actually determines the safety of our daily travel. So we must pay attention to the performance of the tire and learn some daily tire knowledge. Today, the editor will introduce you the common knowledge of the car tire, including how often to replace it? How to identify the tire type and specification of your own model?
Many friends think it's a change every 20000 km, or 40000 km, and some friends say it's a change according to the wear degree of the tyres. In fact, they are all right, but you should refer to the actual situation. You can also change the tyres in the following five ways.
1.Severe wear
The main observation is the wear degree. At the tread pattern of the tire and the sidewall of the side, our tires are designed with wear marks before leaving the factory. You can check whether they need to be replaced according to the wear condition. Under normal circumstances, the wear degree of the front wheel is greater than that of the rear wheel because of frequent steering. It is recommended that the front and rear wheels be replaced after 30000 kilometers to ensure the durability of the tires, Four tyres can be replaced at one time when the tyres are obviously worn next time.
2. After many times of tyre repair
The tyre punctures when driving on the road, which is common. Many people can repair the tyre once for 10 yuan and 20 yuan, but this is not permanent. Especially in the same position, two patches can not appear. Secondly, if the two patches are too close, it is not feasible, which will lead to dangerous risks when driving at high speed. In addition, it is worth mentioning that when a tire is found to be punctured, it must not be pulled out manually. On the one hand, the nail may be ejected due to air leakage, which may cause danger. On the other hand, it will speed up the tire deflation, which will lead to insufficient tire pressure. We are driving in a soft tire state, which is the most harmful to the tire, and even directly scrap the tire.
3. The tyre wall is punctured
The most vulnerable part of the tyre is the tyre wall. If the tyre wall is punctured, my personal suggestion is to replace it directly. Many car owners may have observed the appearance of the car parked. At this time, our front tyres will always be under stress due to the weight of the engine, and the tyre walls on both sides will also slightly bulge, so the tyre wall is punctured. It is not a simple repair to solve the problem. It is easy to split twice in daily life, Even the tyre burst, so it is recommended to replace it directly if the tyre wall is punctured.
4. The tire is bulging
The bulge of the tire often happens to the truck driver. The bulge of the tire indicates that the gold wire inside the tire has broken and deformed, and it is easy to cause the possibility of tire burst when driving. In addition, when you find this problem, you should deal with it in a timely manner as soon as possible to ensure your own safe driving.
5. Tire aging
As for tire aging, we should pay attention to observe the cracks on the tire wall, which represents the aging degree of the tire. If you drive for a short distance, but the car is in a standing state, this situation is prone to aging. The validity period of the tire is generally 3 to 5 years. You can judge it according to the model marked on the tire. Some manufacturers will tell you when purchasing the model that it is generally a warranty for non-human damage within 3 years, In case of aging, replace it in time.
In addition, in addition to paying attention to the obvious problems caused by the above tires, you must pay attention to the maintenance of the tires when driving. First of all, the tires should be adjusted differently according to the different seasons. For example, in summer, it is easy to have a flat tire, so you should reduce the pressure a little in summer, and also pay attention not to turn the steering wheel in place. Now cars have steering assistance, This has also led us to develop many bad driving habits. The rotation of tyres in place is a human factor to accelerate wear.
