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

[WillowDella]

Tires need to be replaced under the following five circumstances: 1. Tires must be discontinued when worn to the wear limit indicator (i.e., tread pattern depth below 1.6 mm). 2. Tire aging (confirmed by physical inspection). 3. Tires with deformed treads or damaged beads, tires with sidewall damage caused by driving under-inflated, and tires corroded by chemicals must not continue to be used. 4. Bulging tires must not continue to be used. 5. Other damages that affect the safety of tire use must not continue to be used. Generally, the service life of tires can be determined by two standards: the usage time should not exceed 5 years; the mileage under comprehensive road conditions should not exceed 60,000 kilometers. Whether to replace tires should be judged based on the actual condition of the tires.
