How many kilometers does a car need to replace its tires?

Car tires need to be replaced every 30,000 to 50,000 kilometers. On smooth asphalt roads, it's around 50,000 kilometers, while on rough gravel roads, it's about 30,000 kilometers. When exceeding these mileage limits, the tread friction coefficient will decrease. On wet or snowy slippery roads, the tire tread's water drainage function diminishes, increasing the risk of skidding. On gravel roads, there's a higher chance of tire blowouts. Tires are the components of a car that come into contact with the ground, directly affecting the vehicle's driving stability and safety. Being made of rubber, tires age over time with prolonged use, hence the need for regular replacement. Even when not in use for extended periods, tires can age, so it's important to check the production date when purchasing new tires.
Changing tires isn't just about mileage. In my years of driving various cars, I've noticed tires typically show significant wear after 50,000-60,000 kilometers. If you frequently drive on highways or rough roads, you might need to check as early as 40,000 km. The key is inspecting tread depth - replace them when worn to the wear indicator (about 1.6mm), otherwise braking distance increases dangerously in rain. Aging matters too; even with low mileage, tires harden and crack after 5+ years, losing grip. I once saw a neighbor nearly crash from tire blowout. To save money, rotating tires evens out wear, but for safety, don't delay replacements. Best to check pressure and cracks every 20,000 km.
