Can run-flat tires still be used after 60,000 kilometers?
2 Answers
Run-flat tires generally need to be replaced every 3-5 years or after driving approximately 60,000-100,000 kilometers. Here are the situations where run-flat tires must be replaced: 1. Sidewall puncture, because run-flat tires can continue to drive after a puncture by relying on the sidewall for support; 2. If the diameter of the puncture hole exceeds 4.2 millimeters; 3. Continued improper driving with insufficient tire pressure, leading to crushing damage; 4. If there is bead damage or deformation, tread deformation, or rubber corrosion by chemicals that cannot be repaired; 5. If the same tire is damaged again after being repaired.
I've been driving for over a decade, and tire maintenance is something I never take lightly. After using run-flat tires for 60,000 kilometers, whether they can still be used depends on their actual wear and aging condition. First, check the tread groove depth—if it's below 1.6mm, replace them immediately, as insufficient tread reduces wet-weather grip and increases skid risks. Next, inspect the sidewalls for cracks or stiffness, which indicate severe rubber aging. Lastly, check the manufacturing date: even if barely used, tires older than five years should be replaced. I recommend having a mechanic inspect them during every service—safety comes first. While replacing run-flat tires costs money, it's far better than risking a roadside breakdown or blowout. Remember, regular tire checks are fundamental to safe driving. I measure tread depth every 20,000 kilometers for peace of mind.
