What is the general lifespan of tires in years and kilometers?

[Kinsley]

Tire lifespan is generally four years or 60,000 kilometers. The following are precautions for car tire maintenance: 1. Pay attention to tire pressure: Air pressure is the lifeblood of tires. Both excessive and insufficient pressure will shorten the tire's service life. Insufficient pressure increases tire body deformation, easily causing cracks on the tire side while generating flexing motion, leading to excessive heat generation, promoting rubber aging, and causing fatigue and breakage of the cord layers. 2. Regularly check front wheel alignment: Front wheel alignment significantly affects tire lifespan, with front wheel toe-in and camber being the primary factors. Excessive camber mainly accelerates shoulder wear (uneven wear), while improper toe-in mainly accelerates wear on the inner and outer sides of the tire. 3. Be mindful of driving habits: Choose road surfaces carefully while driving, avoiding sharp objects like stones, glass, and metal that may puncture or scratch tires, and steer clear of chemical spills that could adhere to and corrode tires. When driving on roads with significant curvature, try to stay centered to reduce uneven tire wear caused by increased load on one side.
