The replacement cycle of tires is usually between 3 to 5 years, or considered when driving 60000 to 80000 kilometers, depending on various factors including wear and tear, aging phenomenon, driving environment, and driving habits.

Here are some key factors that affect tire life:

Wear level: The depth of tire tread will gradually decrease with the increase of driving mileage. When the depth of the tread is less than 4 millimeters, the grip of the tire will significantly decrease, increasing the risk of traffic accidents, so it should be replaced in a timely manner. ‌

Aging phenomenon: The main material of tires is rubber, and prolonged exposure to air can cause rubber aging. Aging tires will harden and crack, affecting their performance and service life. Generally speaking, if a tire has been used for more than 5 years and its tread depth is still usable, it is recommended to replace it to avoid potential safety risks.

Driving environment and driving habits: Driving on bumpy roads, sudden acceleration, sudden braking, etc. can accelerate tire wear. Car owners should pay attention to maintaining good driving habits and driving environment to extend the service life of tires.
