After how many kilometers should car tires be replaced?

[HaileyRose]

Car tires should be replaced after driving 60,000 to 80,000 kilometers. Tires are typically made of wear-resistant rubber materials and can be classified into solid tires and pneumatic tires, with pneumatic tires consisting of inner tubes and outer tires. The functions of tires: 1. Support the entire weight of the vehicle and bear the load of the car; 2. Transmit traction and braking torque to ensure the adhesion between the wheels and the road surface; 3. Reduce and absorb vibrations and impacts during driving, avoiding severe vibrations and premature damage to car components; 4. Adapt to the high-speed performance of the vehicle; 5. Reduce noise during driving. Car tire maintenance methods: 1. Regularly check tire pressure; 2. Remove debris from tire treads; 3. Inspect tire wear and replace them promptly based on wear conditions; 4. Perform four-wheel rotation, which ensures even force distribution across all four tires and prevents excessive wear.
