How many kilometers to change tires?
2 Answers
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.
I see many people asking how often tires should be replaced, and mileage is indeed not a fixed standard. Generally speaking, tires can last between 50,000 to 100,000 kilometers, but it depends on specific conditions. Having driven for over a decade, I've noticed tire wear is greatly influenced by driving habits: if you frequently drive in congested city traffic with sudden acceleration and braking, you might need to inspect them around 50,000 to 60,000 kilometers; if you mostly drive smoothly on highways, you can stretch it to over 80,000 kilometers. More importantly, check for tire wear indicators, such as tread depth—if it's less than 1.6 mm, replace them immediately to avoid slipping in rainy conditions, which poses significant safety risks. Also, don’t overlook the time factor; tire rubber ages, so even with low mileage, replacement is recommended after five years. I make it a habit to have a mechanic check them every six months—it’s hassle-free and ensures safety.
