Do all four tires need to be replaced at 60,000 kilometers?

It depends on individual driving habits and the duration of use. Although rear tires generally experience less wear, tires that have been used for a long time will age and become unsafe. Check the degree of tire wear: There is no officially certified accurate mileage for tire usage. However, based on the shared experiences of many car owners, generally after driving about 50,000 kilometers, the tread grooves of the tires should be nearly worn out. Additionally, the sidewalls may age and crack under prolonged stress fluctuations, leading to reduced grip and an increased risk of blowouts. Therefore, it is recommended to replace the tires. Judging by wear indicators: Many people may not notice the wear indicators on tires, which are currently the most authoritative standard for determining when tires need replacement. When the tire wear reaches the indicator mark, it means the tread depth is less than 1.6mm, significantly reducing the tire's ability to channel water. This makes driving in rainy or snowy conditions very dangerous.
