Under What Circumstances Should Car Tires Be Replaced?
2 Answers
Car tires should be replaced under the following circumstances: Tire damage due to running flat must be replaced: Sometimes, after a tire is damaged and promptly repaired, driving while underinflated may cause the tread or sidewall to be crushed and damaged. In such cases, do not attempt to repair it again to avoid potential hazards. Tires eroded by chemicals must be replaced: If the vehicle accidentally drives over a road surface contaminated with chemical substances, the rubber-made tires can be easily corroded by these materials. In such situations, do not attempt to repair them; immediate replacement is recommended.
I've been driving for over 20 years and what I fear most is tire trouble. The key moments to change tires are: first, insufficient tread depth - generally below 1.6mm is dangerous. You can insert a one-yuan coin vertically into the tread; if too much of it is exposed, it's time to replace. Second, uneven wear, such as severe wear or bulging on one side of the tread, which affects wet road grip and may cause skidding during braking. Tire age is also crucial - tires over six years old may burst due to rubber aging even if they look fine. Damage like bulges, cracks, or multiple repairs should be addressed immediately. Additionally, consider replacement after about 40,000 miles of driving. Don't forget to check that tire pressure is normal to prevent accelerated wear. Safety first - during every maintenance check, I have the mechanic inspect the tire condition to avoid regrets later.
