Do tires need to be replaced after driving 40,000 kilometers?

[StRosalie]

If the vehicle has been driven for 40,000 kilometers within 5 years and the tire wear is not severe, replacement is unnecessary. However, if the tires are over 5 years old or show significant wear, they should be replaced. The wear indicator height for passenger car tires is 1.6mm, while for load-bearing tires it is 2.4mm. The functions of tires include: 1. Supporting the entire weight of the vehicle and bearing the load; 2. Transmitting traction and braking torque to ensure adhesion between the wheels and the road surface; 3. Reducing and absorbing vibrations and impacts during driving, preventing severe vibrations and premature damage to vehicle components; 4. Adapting to the high-speed performance of the vehicle, reducing driving noise, and ensuring safety, handling stability, comfort, and fuel efficiency.
