How many kilometers should car tires run before needing replacement?

Generally, the replacement cycle is approximately within 3-5 years or 40,000-60,000 kilometers. Due to the influence of driving habits and road conditions, there may be some variations. It is not recommended to judge whether replacement is needed solely based on mileage or time. Below is extended information on determining whether car tires need replacement: Degree of wear: Depends on the tire wear indicators. If the tire wear reaches the position of the wear indicators, it means the depth of the tread grooves is now less than 1.6 millimeters. To ensure driving safety, it is necessary to replace the tires with new ones as soon as possible. Once the depth of the tread grooves on the tire falls below 1.6 millimeters, it is not just a matter of reduced performance but also poses safety risks. Tire date: There will be a 4-digit number on the sidewall of the tire indicating its manufacturing date. The first two digits represent the week number, and the last two digits represent the year. After knowing the production date, under normal circumstances, you only need to add 5 years to the production date to infer the optimal service life of the tire. Actual mileage driven: The normal mileage is about 40,000-60,000 kilometers. After exceeding this mileage, the risk of driving will be greatly increased.
As someone who cares about family travel safety, I always remind my friends that tire replacement isn't just about mileage. Generally, regular tires should be considered for replacement after 50,000 to 60,000 kilometers, but the key is to check the actual wear condition. For example, tires have wear indicator lines - if the tread depth is below 1.6mm, even if only 30,000 kilometers have been driven, immediate replacement is necessary. Otherwise, braking distance in rainy conditions will significantly increase, making skidding and accidents more likely. I've seen many accidents caused by tire aging, especially during highway driving. Besides mileage, road conditions matter too - tires wear much faster on bumpy roads. I recommend checking every six months. Don't wait for strange noises or air leaks - safety should always come before saving money.
