What is the service life of sedan tires in kilometers?
2 Answers
Sedan tires typically have a service life of around 80,000 kilometers. The functions of tires include: 1. Cushioning the impacts experienced during vehicle operation; 2. Ensuring good ride comfort and smooth driving; 3. Maintaining excellent adhesion between the wheels and the road surface, thereby improving the traction, braking, and off-road capability of the vehicle; 4. Supporting the weight of the vehicle. Tires are circular elastic rubber products mounted on various vehicles or machinery for ground contact and rolling. Situations that require replacing sedan tires include: 1. Severe tire wear; 2. Tire aging with numerous small cracks on the tread pattern; 3. Tires with deformed treads or damaged bead areas; 4. Tires with bulges.
Honestly, there's no exact mileage figure for tire lifespan. After driving for ten years, my most straightforward observation is: check the small raised wear indicators in the tire grooves! When the tread wears down to their level, it's time for replacement. For daily commuting, most passenger tires can last 5 to 6 years or 50,000 to 80,000 kilometers without issues. But pay special attention—if you frequently drive on rough roads or have an aggressive driving style, any fine cracks on the tire sidewalls warrant an early inspection. Last week, while helping a friend check his car, I noticed his vehicle had been parked outdoors for four years. Despite only covering 30,000 kilometers, sun and rain had hardened and cracked the tread rubber, significantly reducing grip. Remember, even the best tires shouldn't be used beyond six years—rubber degradation is far more dangerous than tread wear.
