What Are The Factors That Affect Tire Life?

1. Tire selection and installation
The correct tire installation is directly related to the service life of the tire, especially when replacing new tires. Tires of different types and patterns must not be mixed at will because the actual size and load capacity of each tire are different. In addition, if you cannot fully master the skills of changing tires yourself, we recommend that you go to a professional tire shop or a vehicle authorized repairer to replace them.

2. Working air pressure
Tire pressure that is too low or too high will affect the service life of the tire. If the tire pressure is too low, its radial deformation will increase, and both sides of the sidewall will deform excessively, resulting in wear on both shoulders of the crown, which will increase the temperature of the tire and seriously reduce the service life of the tire.
If the tire pressure is too high, the rigidity of the tire will increase, and the deformation and ground contact area will decrease, which will increase the unit pressure in the middle of the tread and increase road wear. The central wear of the crown occurs, which affects comfort and reduces tire life. Tests have proven that if the air pressure is increased by 25%, tire life will be shortened by about 30%.

3. Tire load
The greater the load on the vehicle, the shorter the life of the tires. There is no doubt about this. Especially in the case of overload, it is more prominent. Tires produced by regular tire manufacturers are marked with load index. Tires should be used within the maximum load capacity corresponding to the specified load index. ​

4. Driving speed
Tires produced by regular tire manufacturers are marked with a speed level index. Tires should be used within the maximum driving speed corresponding to the specified speed class index.

5. Tire temperature
When the vehicle is driving, the tires are stretched, compressed and rubbed, causing the tire temperature to rise. Excessively high temperatures can easily aggravate tire wear and even cause a puncture. ​

6. Chassis condition
The parallelism of the front and rear axles, four-wheel alignment, the working condition of the brake device and the technical condition of other chassis components will affect the life of the vehicle tires to varying degrees. Once a serious traffic collision occurs, the car owner must drive the vehicle to a professional repair station for chassis condition inspection and adjustment. ​

7. Road conditions
If the vehicle is driven on gravel roads or poor road conditions for a long time, the service life of the tires will definitely be reduced. This is no exception for off-road vehicle tires.

8. Driving habits
This is a factor directly related to the car owner. Starting too fast, turning suddenly, emergency braking, driving at high speed in poor road conditions, frequently going up and down curbs, and tires scraping against obstacles when parking, etc., will all cause serious wear and tear of the tires, thereby reducing the service life of the tires.

9. Tire maintenance
Timely rotation of tires, selection of appropriate tread patterns, daily maintenance, regular tire pressure checks, timely repairs and frequent removal of stones and foreign objects in the tire treads are all important factors in extending tire life.

10. Vehicle maintenance
Many car maintenance experts say that a vehicle should be "repaired 30% and maintained 70%". Don't wait until something breaks down before driving it to a repair station for repair. The regular maintenance of vehicles is also closely related to the extension of tire life. Regular inspection and maintenance of four-wheel alignment, steering knuckles, wheel bearings and suspension systems are indispensable. ​

11. Maintenance knowledge
First of all, check the surface of the tire frequently to ensure that the tire is clean. Drivers should develop the habit of regularly checking their cars, and regularly check whether there are stones or other foreign matter in the tread grooves of the tires. At the same time, they should pay attention to the warranty period of the tires. The service life of the tires is generally 2-3 years or 6-6 years of driving. About 100,000 kilometers. Tires should be replaced immediately when the tread depth is 1.6mm (minimum wear). The overall performance of tires that have exceeded their shelf life (especially spare tires, the life of spare tires is roughly 3 years) has declined.
Secondly, there are changes throughout the year, so the tire height must be determined. Drivers should prepare a tire pressure gauge with the car and carefully check the tire pressure of each tire before leaving the car, because after the car has been resting for a period of time, the tires have reached the 4 hours required to completely cool down. The measurement at this time The most accurate is that the standard tire pressure is about 2.2~2.6bar. Of course, it will fluctuate slightly in summer or winter. Too high a tire pressure can easily increase tire wear and may even cause a puncture, while too low a tire pressure can increase fuel consumption and cause the vehicle to feel bumpy.
In addition, it is important to always have a spare tire and tire swap. If the vehicle has problems such as deviation, heavy steering wheel, or tire wear on one side while driving, these phenomena are all reminders to the owner that the four-wheel alignment of the vehicle needs to be adjusted immediately. Due to the steering wheel of the vehicle, the front wheels wear faster than the rear wheels. In order to extend the service life of the tires, regular tire rotation can make the tires wear evenly. Auto repair experts recommend that front-wheel drive vehicles perform a four-wheel rotation every 8,000 kilometers.

12. Check
During driving, the tires, as the "foot" of the car, are just like people walking everywhere with their feet, experiencing different places and encountering different situations. Therefore, the car owner should check the condition of the tires carefully at this time to see if there is any damage. Debris or foreign objects are mixed in. If found, they should be cleaned up in time. If not cleaned up in time, some parts will fall off automatically while the car is driving, and some will slowly "erode" the tires deeper and deeper. To a certain extent, they will puncture the tire, leading to tire rupture, puncture, air leakage, etc., which may easily cause their own danger.
