How many kilometers should a car drive before changing tires?

Around 60,000 to 80,000 kilometers. Relevant information: Indicators for tire replacement: Generally, when the tread is worn down by half, it's time to start considering tire replacement. Additionally, after several years, the elasticity of the rubber begins to weaken, so for driving safety, it's advisable to replace the tires. Another indicator for private car tire replacement is the number of punctures. If there are more than three punctures, it's also a good idea to replace the tires, especially if the sidewall is damaged. The replacement time for private car tires is also related to age. If the car is mostly parked in an open-air parking lot, consider replacing the tires after 4 years. Daily tire maintenance: Check the air pressure of all tires, including the spare, once a month when they are cold. Do not exceed the reasonable speed limits required by driving conditions and legal restrictions. Regular wheel alignment and balancing are important for ensuring driving safety and achieving optimal mileage.
I've been driving for over a decade, and when it comes to tire replacement, mileage alone isn't the deciding factor. Generally, tires can last between 40,000 to 100,000 kilometers before needing replacement, but on average, you should start checking them around 50,000 kilometers. The most crucial aspect is the wear level. My method is inserting a one-yuan coin into the tire tread—if the coin's edge isn't visible through the tread, it's time for new tires. Tire age is equally important; after six years, the rubber hardens and becomes prone to cracking, increasing the risk of a blowout. Even if the tires have only covered 10,000 to 20,000 kilometers, they should be replaced. Driving habits significantly impact tire wear. For instance, frequent hard braking in city driving or high tire temperatures during long highway trips accelerate wear, possibly necessitating replacement before 40,000 kilometers. From a safety perspective, heavily worn tires increase braking distances and are more likely to skid, especially in rain or snow, leading to accidents. That's why I recommend a professional inspection every six months or 10,000 kilometers—don't wait for a problem to arise. Maintaining proper tire pressure and regular tire rotation can also extend their lifespan.
The mileage for changing tires varies from person to person. Since I use my car frequently, I usually consider replacing them every 40,000 to 70,000 kilometers. A simple method is to check with a mobile app or a coin: if the tire tread depth is less than 1.6 mm (about the height of the edge of a one-yuan coin when submerged), it's time for new ones. Driving conditions are crucial; for example, frequent travel on mountain roads or bumpy terrain accelerates wear. New car tires can remain stable for up to 50,000 kilometers, but don't push them too hard. Here's a money-saving tip: buying durable brands may be more expensive upfront, but they are more cost-effective when spread over the mileage. Additionally, you can rotate the tires during each maintenance check. From a safety perspective, worn-out tires are more prone to losing control during sharp turns—I once had a close call, and since then, I've made it a habit to check tire pressure and appearance quarterly. Don't overlook the tire's expiration date either; aging beyond five years increases risks. In short, don't just rely on mileage—comprehensive judgment is the most reliable.
