The tire is like the four legs of a vehicle. Without the tire, the car can't move. The importance of the tire can be imagined. However, in the actual use of the car, many owners pay little attention to the tires, and the maintenance and repair of the tires are not timely, which is actually a behavior with potential safety hazards. Next, I'd like to briefly introduce some knowledge about automobile tires.
The tire pressure changes with the change of temperature. If the tire pressure is insufficient, it is likely to cause a tire burst. In general, the chance of a tire burst because of air leakage is higher. If the tire continues to run when the tire is leaking, the sidewalls of the tire will be deformed. When driving for a long time, a large amount of heat will be accumulated inside the tire, which will eventually change the air pressure inside the tire, resulting in the tire burst.
It is reported that tire burst accidents caused by air leakage account for almost half of tire burst accidents. Therefore, it is recommended that the owner must develop the habit of regularly checking the tire pressure. Owners can buy a TPMS and monitor it every one or two weeks, or they can often visually check whether the tire is normal. The most reliable way is to go to the 4S store every half month or one month for testing.
Some car owners think that they can continue to use the tire as long as it is not damaged. In fact, the tire has a service life. If the tire expires, it cannot continue to use. In general, the service life of the tire is 2-3 years or about 60000 kilometers. If the service life is exceeded or the tire has been seriously worn, it should be replaced in time.
The quality guarantee period of rubber is generally about 5 years. And the service life of tire is closely related to the conditions such as use method and storage. Therefore, the owner should pay close attention to the tires. Once the tire is found that the tires are aging, accidentally damaged and severely worn, it should be replaced in time.
The "damaged" tire generally refers to the leakage on the sidewall of the tire. The road the owner takes in daily driving is relatively complex, so the phenomenon of tyre puncture is inevitable. Generally speaking, the puncture on the front of the tire can be repaired, and the tire can be used normally after repair. However, if the puncture is on the sidewall or the angle between the sidewall, the tire surface are hard to repair, and it should not be used again even after repair.
The owner should check whether the tire is damaged frequently in daily driving. Once the damage is found, repair or replace it in time. If some stones are found in the tire grooves, they should be removed in time to avoid deformation of the tire crown. Also, do not allow the tires to come into contact with oil and chemicals.
Every time the tyres run for a period of time, they need to be rotated so as to keep the uniform wear of the tyres. Every 5000 km of vehicle driving, tire rotation shall be done, and every 5000-10000 km of vehicle driving, four-wheel tire rotation shall be done to avoid abnormal excessive wear on the tires. It is not allowed to install tires of different models or large difference between the old and the new on the same axle. If the wheel imbalance exceeds the standard, high-frequency swing will occur when driving at high speed, causing tires to wear away, which is not conducive to driving safety. After the tire is repaired, the dynamic balance detection and adjustment shall be carried out, and the single side dynamic balance detection value of the tire shall be less than or equal to 40g.
Tire pressure monitor system can help owners find out the possible emergencies in advance during driving, such as tire leakage and blowout. The main function of TPMS is to monitor the abnormal tire pressure and inform the driver in time. TPMS plays a significant role in driving safety, energy saving, emission reduction and wear reduction.
