Detailed Analysis Of Tire Usage Techniques

1. Check the tire. If the tire is scratched on the side of the tire and is too serious to be repaired, you need to replace it with a new tire.

2. The size of tires cannot be changed at will, so you must choose tires that match your car.

3. Since the sealing performance of the tire and the wheel hub is very good, professional equipment must be used to separate the tire from the wheel hub; the tire must be rotated evenly to avoid abrupt disassembly and damage to the wheel hub.

4. Completely remove the tire from the wheel hub. After the tire is removed, check whether the wheel hub is damaged. If a damaged wheel hub is installed with a tire, it will not only not be tightly sealed and cause air leakage, but it will also break and cause danger.

5. Yellow dots and red dots are specially designed on the tire, because when the wheel rotates, it has a center of gravity. The side with the yellow dot is lighter and the side with the red dot is heavier. Therefore, when installing, pay attention to aligning the yellow dot with the valve.

6. If the installation is difficult, you can moisten the tires with clean water. After the new tires are installed, inflate enough to prepare for subsequent balancing.

7. The new tires installed must be dynamically balanced. During driving, if the position of the tires is unbalanced, it will cause the steering wheel to shake. The faster the speed, the greater the vibration; moreover, unbalanced tires will also cause wear. The measurement of dynamic balance has a certain value. When rotating, the weight difference can be measured. According to the machine test, this tire has a difference of 15 grams on the left and 11 grams on the right.

8. In order to make up for the difference, aluminum cards of corresponding weight need to be added. After testing, there is no difference in weight on both sides of the tire. At this time, the tire reaches balance.

9. Check whether the tire is tightly connected to the wheel hub. Just spray foam on the sealing area. If it bubbles, it means there is air leakage. After installing the tires, it is best to do a four-wheel alignment to achieve overall balance. Experts advise not to drive too fast after changing a tire.
