How many kilometers should car tires usually be replaced?
3 Answers
Car tires are usually replaced every 60,000 to 80,000 kilometers. The steps for replacing car tires are: 1. Use a jack to lift the vehicle to a certain height; 2. Remove the screws and take off the tire; 3. Replace with a spare tire and release the jack. The functions of car tires are: 1. To support the entire weight of the vehicle and bear the load of the car; 2. To transmit the torque of traction and braking, ensuring the adhesion between the wheels and the road surface; 3. To reduce and absorb the vibrations and impact forces during driving, avoiding severe vibrations and early damage to car components; 4. To adapt to the high-speed performance of the vehicle; 5. To reduce driving noise.
There's no fixed rule for changing car tires, usually it's based on mileage. From my personal experience, tire manufacturers recommend replacement every 50,000 to 80,000 kilometers, but this isn't an absolute figure. The key is to check the actual condition of the tires. For example, if the tread depth is less than 1.6mm, you should consider changing them. You can insert a dime vertically into the tread - if you can see the outer edge of the coin, it indicates severe wear. Tire aging is also crucial. Even if you've only driven 20,000-30,000 kilometers, after five or six years the rubber hardens and loses grip. In cities with frequent traffic jams and braking, tires wear faster and may need replacement at 60,000 kilometers. On highways with smooth conditions, you might stretch to 70,000 kilometers. Check tire pressure quarterly to ensure proper inflation, as incorrect pressure causes uneven wear and reduces lifespan. I personally get my tires professionally inspected at the dealership annually for early detection of potential safety issues.
After driving for over 30 years, tire replacement timing depends on actual driving conditions and inspections. The general rule is to change them between 50,000 to 80,000 kilometers, but I've seen tires worn out at 60,000 km and others still in good condition at 80,000 km. The key is observation: check the tire wear indicators - if they're flush, replace the tires regardless of mileage; also inspect sidewalls for cracks or bulges, as aging and damage are more dangerous. City driving with frequent hard stops wears tires faster, while rough off-road conditions accelerate wear. Uneven tire pressure can cause one-sided wear. For peace of mind, measure tread depth monthly with a tread gauge - safety comes first. I recommend not exceeding 70,000 km, especially during rainy seasons when reduced traction increases slipping risks. Fellow drivers sharing experiences provides the most reliable advice.
