What is the lifespan of tires in kilometers?
2 Answers
Tire lifespan is approximately 40,000 to 60,000 kilometers. The method for changing tires is: 1. Place the jack on the chassis support's locking position and use a wrench to loosen the screws diagonally; 2. Hook the support onto the jack and attach the wrench to the end of the support, then rotate the wrench clockwise to lift the tire off the ground with the jack; 3. Remove the screws and take off the tire for replacement. Tires are circular elastic rubber products assembled on various vehicles or machinery for ground rolling. Their functions are: 1. Transmitting driving force, braking force, and steering force through the tires; 2. Supporting vehicle loads; 3. Reducing and absorbing vibrations and impacts during vehicle operation.
Tire lifespan really can't be judged by mileage alone – it took me seven or eight years of driving to truly understand this. Regular passenger car tires may last 50,000 to 80,000 kilometers, but each vehicle's fate differs. If you're constantly driving on gravel roads, tires might need replacement at 40,000 km. My neighbor, who drives aggressively with frequent hard braking and sharp turns, wore out two sets of tires in under three years. The key is learning to read wear indicators – when those small raised bars in the tire grooves become flush with the tread, traction becomes comparable to driving on ice. There's also a time limit: rubber inevitably ages and cracks after five or six years. My car that sat unused for two years developed spiderweb cracks across all tire surfaces. Don't forget about tire rotation – swapping positions every 10,000 km ensures even wear across all four tires. This practice extended my tire life by an extra 20,000 km.
