How many kilometers can a sedan tire run before needing replacement?

Car tires need to be replaced after running 30,000 to 50,000 kilometers, and the replacement time can be determined based on road conditions and mileage. The functions of tires are: to transmit driving force, braking force, and steering force to achieve vehicle operation; to support vehicle loads; to reduce and absorb vibrations and impacts during driving, avoiding severe vibrations that could damage car components. Tire maintenance methods include: regularly cleaning stones stuck in tire treads; minimizing exposure to direct sunlight; promptly checking tire pressure; paying attention to suspension maintenance; regularly inspecting front wheel alignment; and adopting careful driving habits, such as choosing smooth road surfaces and avoiding objects that could puncture or scratch tires, as well as chemical spills that may corrode tires.
I'm particularly cautious about tire replacement, as safety is the foundation of driving. My car's tires generally need to be checked and replaced after about 60,000 kilometers, but the actual mileage depends on personal driving habits and road conditions. If you frequently drive on rugged mountain roads or in congested urban areas, the wear is faster, and you might reluctantly need to replace them at 40,000 kilometers. Smooth highway driving can extend their life to over 70,000 kilometers. The key is also to check the tread depth—if it's below 1.6 millimeters, the grip is insufficient, making the tires prone to slipping in rainy weather. I once saw a friend whose worn-out tires blew out on the highway due to delayed replacement, nearly causing an accident. Additionally, tires older than six years should be replaced even if the mileage is low, as the rubber ages and becomes risky. I make it a habit to check tire pressure and tread every three months, addressing any cracks or bubbles immediately. In short, don’t just focus on mileage; regularly assess your tires to prevent accidents.
I've been driving sedans for ten years, and my tire-changing experience tells me there's no one-size-fits-all answer. Typically, tires can last 50,000 to 80,000 kilometers, depending on how you use them. I once replaced my tires at 60,000 km because frequent potholes caused faster wear; when mostly highway driving, they lasted until 75,000 km. Tread depth is crucial—use a coin to test it. If the tread is nearly flat, replacement is a must. Time and road conditions also matter. In winter, cold weather accelerates wear, so I change to winter tires earlier. Check tire pressure monthly to ensure it's normal—underinflation can make tires retire prematurely. Remember, mileage is just a reference; combine it with actual driving conditions for reliability. Don't wait until an emergency to regret it.
