How Long Do Car Tires Last?
2 Answers
Car tires typically last between 60,000 to 80,000 kilometers or approximately 3 to 5 years. The functions of tires are: 1. To cushion the impact experienced during vehicle operation; 2. To ensure good comfort and smooth driving; 3. To maintain excellent adhesion between wheels and road surfaces, enhancing traction, braking, and passability; 4. To bear the vehicle's weight. Tires are circular elastic rubber products mounted on various vehicles or machinery for ground contact rolling. Situations requiring tire replacement include: 1. Severe tire wear; 2. Aging tires with multiple small cracks in the tread pattern; 3. Tires with deformed treads or damaged bead areas; 4. Tires with bulges.
I've been driving for nearly 20 years and concluded that tire lifespan boils down to two factors: time and mileage. Generally, you should pay special attention after four to five years, even if you don't drive much. Rubber deteriorates and cracks, especially on vehicles exposed to prolonged sunlight. When I replaced the tires on my SUV in its fifth year, the surface looked decent but the sidewall cracks were wide enough to fit coins. For frequent drivers, mileage is key - standard tires typically reach their limit around 50,000 km. Remember this rule of thumb: if you can't feel the raised tread wear indicators when inserting your index finger into the main groove, it's absolutely unsafe as wet traction will plummet. Last time when helping a friend inspect a used car on the highway, the thin tire scraped a curb and blew out instantly - buying new tires is always cheaper than repairing car damage!
