How Long Do Tires Last?
2 Answers
Tires generally have a lifespan of four years or 60,000 kilometers. If the tread depth is below 1.5mm or bulges appear, they need to be replaced earlier. The exact timing depends on the degree of tire wear. As the only component of a vehicle that comes into contact with the ground, tires are crucial for driving stability and safety. It is recommended that car owners replace their tires every four years, even if the mileage driven within those four years is relatively low. Tires are circular elastic rubber products mounted on metal rims, designed to support the vehicle body, absorb external shocks, maintain contact with the road surface, and ensure the vehicle's driving performance.
I've got a lot to say about tire lifespan. I remember the last time I changed tires was after running 70,000 kilometers, but what's more crucial is the time factor. Even if you haven't driven much in five years, you still need to check them. I measure tread depth using a dime coin – if the slot reveals the coin's edge, it's dangerous. The safety limit is below 1.6mm, at which point replacement is mandatory. I check tire pressure quarterly, maintaining it at the vehicle manual's standard value. In summer when temperatures are high, I slightly reduce pressure to prevent blowouts, while in winter I increase it for better safety. Proper maintenance can extend tire life by two years. Once I forgot to rotate tires, resulting in faster front tire wear and premature replacement. Now I've learned to rotate every 5,000 kilometers for even wear. Generally speaking, 50,000-80,000 km or 4-6 years is the baseline, but it depends on driving habits and road conditions – areas with lots of gravel require more frequent checks.
