Whether you are a new driver or an experienced driver, you should know when to replace tires and how to check them yourself. There are a total of 5 suggestions.
1： Will check the tire wear limit
There are many small steps distributed in the tire pattern, which represent the wear limit of the tire.
When the tread of this tire becomes very shallow and approaches a step, although the main performance of the tire will not be affected, its drainage performance will deteriorate. When passing through waterlogged roads, the grip ability will be slightly worse. We need to consider replacing it.
2： Will check the tire production time
Find this set of numbers on the edge of the tire, such as 4220 on this tire, which represents that this tire was produced in the 42nd week of the 20th year. The normal service life of a tire is only 5-6 years. Wind, sun, and rain can make the rubber of the tire harder, reduce the friction coefficient, and the braking effect is not as good. Of course, the actual use of this tire for 5-6 years also depends on the actual situation.
When there are many cracks and small fissures at the edges of the tire, it is necessary to carefully consider (indicating that the tire is beginning to age). If your car has high intensity, it is recommended to replace the tire.
3： Conduct a thorough tire inspection
When you have nothing to do, you can touch the outer edge of this tire yourself to see if there are bulges. If there are bulges, they can be clearly felt. Once a tire develops bulges, it means that the curtain layer inside has already been broken, indicating that the tire has experienced "meridian rupture". Why does it swell? This is related to our usual practice of rushing into a pit with speed, parking and directly hitting the curb, and so on.
Another issue is the low pressure of the tire, where areas such as the shoulder that were not originally in contact with the ground begin to come into contact with the ground. This can also lead to damage to the inner ply of the tire, and in severe cases, structural damage, ultimately resulting in a blowout.
We have clearly indicated the standard tire pressure values for tires under different load conditions at the positions of the B-pillar and fuel tank cap on our car. You can also come to our store to check and inflate the tires. If you are a Tmall car maintenance member, you can also enjoy a free patch tire repair.
4： Regularly perform tire rotation
Most of our cars used to be front wheel drive, and the front wheels not only provide power for forward and backward movement, but also have steering functions, so the wear of the front wheels is greater than that of the rear wheels.
Regular four-wheel rotation helps to achieve more uniform wear of the front and rear wheels, which can reduce the frequency of tire replacement.
5： Pay attention to the size when replacing tires
For example, tire 205/50 R17 is its size and model, and replacement can only be done with the same model.
Do you prefer something more sporty or quieter? It depends on your preference for the brand, but the size must be correct. However, changing the size is not acceptable.
