How many kilometers does a car need to run before replacing tires?

Cars need to replace tires after running about 60,000 to 80,000 kilometers. The steps for replacing tires are: 1. After parking and turning off the engine, use the handbrake to stop the car; 2. Place heavy objects in front of and behind the wheels to prevent sliding, and place a triangular warning sign behind the car; 3. Use a wrench to loosen the screws of the tire that needs to be replaced in a diagonal manner; 4. Place the jack on the side where the tire needs to be replaced and lift the vehicle to a certain height; 5. Remove the screws and take off the tire; 6. Replace it with a spare tire or a new tire, and tighten the screws diagonally; 7. Release the jack to lower the vehicle, and make sure the screws and nuts are tightened. The functions of tires are: 1. To cushion the impact when the car is driving; 2. To ensure the car has good comfort and smooth driving; 3. To ensure good adhesion between the wheels and the road, improving the car's traction, braking, and passing ability; 4. To bear the weight of the car.
I've been driving for 20 years, and when it comes to tires, you really can't just rigidly focus on the mileage. Generally, it's recommended to start paying attention after 50,000 to 70,000 kilometers. For experienced drivers like me who frequently drive on highways, it's necessary to replace them after around 50,000 kilometers because high speeds and frequent braking accelerate wear. However, for friends who only drive in the city with smooth driving habits, the tread might still be deep at 60,000 kilometers. The key is regular inspections—once the wear indicators become visible, it's time to replace them, as the risk of skidding on wet and slippery roads during rain is too high. Now, I check tire pressure and wear every six months, using a one-yuan coin to measure tread depth—it's easy and reassuring. Don't wait for an accident to regret; safety comes first above all else. Actual driving habits and road types have a huge impact; wear on rural dirt roads is much faster than on highways.
From a safety perspective, I must say that driving with tires worn to the limit is extremely dangerous, especially as a blowout at high speeds can lead to accidents. The 50,000 to 70,000 kilometers range is a reference value, but don't just focus on the mileage—the key is to check the tread depth. If it's below 1.6 millimeters, it's time to replace them. For example, I take sharp turns frequently, which causes faster wear. The wear indicators, those small raised bars in the tire grooves, can directly show the condition. A simple coin test—if the outer edge is exposed—means it's time to act. Incorrect tire pressure also accelerates the problem, so I've made it a habit to do a quick check every time I refuel. Be extra cautious during significant weather changes, as rain reduces friction and makes loss of control more likely. To prevent accidents, I recommend doing a self-check every 10,000 kilometers—safety should never be taken lightly.
From an economic perspective on tire replacement, don't change them too early to avoid waste, but don't delay too long to prevent accidents. I aim to control replacement at around 60,000 kilometers for optimal cost-effectiveness – changing too early is wasteful money, while exceeding 70,000 km risks blowouts with higher repair costs. I choose durable all-season tires to extend lifespan, and daily driving with less aggressive maneuvers can save some money. Your driving habits matter – smoother driving makes tires last longer. Brand also affects pricing, just find one with good cost-performance ratio. Regularly adjusting tire pressure helps prevent premature wear.
