How often should tires be replaced?

[DiStephanie]

Tires should be replaced after driving 80,000 kilometers. Tire companies recommend replacement every 3 to 5 years, depending on the wear condition within the service life. Tires must be replaced immediately under the following circumstances: 1. The tire wear has reached the wear limit indicator; 2. Tires that have aged need replacement; 3. Tires with deformed treads or damaged bead rings, tires that have been driven flat causing sidewall damage, or tires corroded by chemicals cannot be used; 4. Tires with bulges cannot be used. Tires are circular elastic rubber products mounted on various vehicles or machinery for ground rolling. They are often used under complex and harsh conditions, enduring various deformations, loads, forces, and high and low temperatures during operation. Therefore, they must possess high load-bearing capacity, traction performance, and cushioning performance, while also requiring high wear resistance, flex resistance, and low rolling resistance and heat generation.
