Generally speaking, the tires installed on the car can be used for four years, so it is recommended that you replace the tires every four years.
Buying new tires must depend on the date of production, because tires also have a shelf life.
Under normal circumstances, the shelf life of unused tires is three years. Don't buy it for more than three years.
After installing new tires, be sure to re-check the dynamic balance of each wheel to prevent the wheels from shaking abnormally when driving at high speed.
If the wheels shake abnormally when driving at high speed, it will affect the handling and driving stability of the car.
When using the car at ordinary times, be sure to check the tire pressure regularly. Air pressure is very important to tires.
Tire pressure should not be too high or too low.
If the air pressure is too high, the contact area between the tire and the ground will become smaller.
If the air pressure is too low, it will lead to the wave deformation of the tire at high speed and accelerate the aging speed of the tire.
