What is the lifespan of car tires?

[LaValentina]

Car tires can generally be used for 4-5 years. Below is relevant information about car tires: 1. Functions of tires: Support the entire weight of the vehicle, bear the load of the car, and transmit forces and moments in other directions; transmit traction and braking torque to ensure good adhesion between the wheels and the road surface, thereby improving the car's power performance, braking performance, and passability; work together with the car suspension to mitigate impacts during driving and dampen resulting vibrations; prevent severe vibrations and early damage to car components, adapt to the vehicle's high-speed performance, reduce driving noise, and ensure driving safety, handling stability, comfort, and energy efficiency. 2. Tire lifespan: The lifespan of tires is related to many factors, such as climate, road conditions, driving habits, installation, maintenance, etc. According to international regulations, if tires are used normally, they must be replaced when the tread depth wears down to 1.6 millimeters.
