What are the situations when car tires need to be replaced?

The situations when car tires need to be replaced are: 1. Exceeding the service life and mileage; 2. Severe tread wear; 3. Abnormal tire pressure; 4. Serious tire cuts. The functions of tires are: 1. Supporting the entire vehicle's weight; 2. Buffering vibrations and impacts from the road surface; 3. Transmitting driving force and braking force through the adhesion performance between tires and the road; 4. Ensuring a certain mileage through the tire's wear resistance and impact resistance. Precautions for replacing car tires are: 1. Check the expiration date, inventory should not exceed 3 years; 2. Inspect whether the tread pattern and color are normal; 3. Observe whether the joint between the tread and sidewall is smooth; 4. Avoid mixing tires of different structures and sizes.
As a long-term driver, I've learned that tire replacement shouldn't solely rely on maintenance schedules. Daily observation is crucial: use a one-yuan coin to test tread depth - if the national emblem's top is covered by treads, the condition is acceptable, but worn-out treads signal danger. Even with low mileage, tires over 5 years old should be considered for replacement as rubber hardening significantly increases high-speed blowout risks. I once experienced a rainy-day skid accident caused by ignoring sidewall cracks. Rotate front/rear tires every 8,000km to extend lifespan by 20%. Always check for bulges or cuts before long trips - never compromise on safety.
