How many kilometers to change tires?

[JamesonLynn]

Most tires have a service life of four years. Based on the average annual mileage of 20,000 kilometers for household vehicles, this equates to 80,000 kilometers. The replacement should be determined by whichever comes first between mileage and time. It is recommended to replace tires every four years. Tires are rubber products, and rubber deteriorates with prolonged use. Aged tires develop surface cracks, and even if the mileage is relatively low, replacement is advisable. When purchasing new tires, always check the production date clearly. Generally, unused tires have a shelf life of three years. If the tires have been in storage for over three years, they should not be purchased. After changing tires, it is essential to recheck the dynamic balance of all four wheels to prevent abnormal vibrations during high-speed driving. During regular vehicle use, frequently inspect tire pressure, as it is crucial for tire performance. Tire pressure should not be too high or too low. Insufficient pressure can cause wave-like deformation of the tires, reducing their lifespan. Excessive pressure can lead to poor traction and affect driving stability.
