What are the criteria for replacing car tires?
1 Answers
The criteria for replacing car tires are when the tire rubber has aged to the critical point of deterioration, the tire has worn down to the wear indicator, the tire sidewall is bulging, the tread is deformed or bulging, the tire has a leak that cannot be repaired, the tire produces unexplained noises while driving, exhibits uneven wear, misalignment, or abnormal wear. Lifespan of car tires: The lifespan of car tires is generally 3-5 years or a mileage of 60,000-80,000 kilometers under normal driving conditions. However, depending on the driver's habits, road conditions, and parking environment, the lifespan of car tires may vary. Hazards of using expired tires: Expired tires have aged rubber, making them prone to cracking, reduced flexibility, and severely diminished heat dissipation. Not only does comfort drastically decrease, but acceleration and braking performance also suffer significantly. High-speed driving carries the risk of a blowout, so expired tires must be replaced even if they haven't reached the wear indicator. Method for replacing tires: Park the car, turn off the engine, and engage the handbrake to prevent sliding. Loosen the bolts in a diagonal pattern, lift the vehicle to a certain height, remove the bolts and take off the old tire, install the new tire and tighten the anti-theft bolts in a diagonal pattern, lower the vehicle and tighten the bolts and nuts. Precautions for tire replacement: Choose tires of the same specifications, replace the valve stem at the same time, pay attention to the installation direction and inflation, check the tire pressure, perform a wheel alignment after replacement, slightly loosen the fixing bolts before using a jack to lift part of the vehicle when removing the tire, and choose tires with guaranteed quality.
