General knowledge of car tire maintenance.
1. Frequent removal of debris in the tread
When we drive every day, it is inevitable that we will crush small stones, metal fragments, etc. on the side of the road, and most of the wheels will crush foreign objects and most of them will adhere to the wheels. If it is not cleaned for a long time, it will cause great damage to the tires, especially when driving at high speeds. If there are foreign objects in the tire pattern that can easily cause the tire to puncture, it is dangerous. Therefore, if you find small stones and so on, you need to use a key or the like to pull out, as far as possible to ensure that the tires are clean.
2. Check the wear of the tires
The three small bumps are scientifically called "tread wear marks". When the tire wear reaches this convex point, it means that the tire needs to be replaced. The traction and grip of the new tire and the old tire are very different. Those tires that wear very badly , The grip is weak, and it is easy to slip. Therefore, the tire should be replaced in time according to the wear.
3. Prevent road shoulders and potholes
There are many car owners who like to park their car on the shoulder of the road, but I don’t know that this will cause the tire to be greatly squeezed, which may easily cause the cord on the side of the tire to break, causing the tire to bulge. In addition, the pits of the road surface should also be avoided, because when the tire runs through the pit, the tire will also be squeezed. The larger the pits and the higher the vehicle speed, the greater the squeezing force of the tires. This will also cause the tires to bulge, which will shorten the life of the tires.
4. Check tire pressure regularly
Tire pressure is the most important factor affecting tire life. It cannot be too high or too low. Inflate according to the tire pressure marked on the vehicle. It should be noted that the tire pressure will change with temperature. Under the influence of thermal expansion and contraction, the tire pressure will also decrease in winter. If the tire pressure is improperly increased, it will not only increase the fuel consumption of the car, but also accelerate the wear of the car tires. Therefore, the tire pressure can be increased appropriately in winter, but it should be controlled within the specified range. In summer, when the temperature is high and the tire pressure is too high, it is easy to cause a flat tire. Therefore, the tire pressure should be lower in summer.
