What are the situations that require tire replacement?
2 Answers
There are several situations that require tire replacement: 1. Tire deformation; 2. Severe damage to the tire body; 3. Severe damage to the tread; 4. Damage to the bead; 5. Bulging or cracking on the tire sidewall; 6. Damage caused by driving with insufficient tire pressure; 7. Tires that have been repaired more than three times; 8. Tires worn to the wear limit; 9. Chemical corrosion; 10. Severe aging and peeling. The functions of tires are: 1. Transmitting driving force, braking force, and steering force to enable vehicle operation; 2. Supporting the vehicle load; 3. Reducing and absorbing vibrations and impacts during driving to prevent severe vibrations from damaging vehicle components.
As a seasoned driver, I've had to change tires quite often, mainly when they're excessively worn, such as when the tread depth falls below 1.6 mm. At that point, I have to replace them immediately, otherwise, driving in the rain can become dangerously slippery. Additionally, if a tire is punctured by a nail or sharp object and can't be repaired, or if there are bulges or cracks on the sidewall, it's not worth risking—it must be replaced right away to avoid a blowout and potential accident. I've also encountered cases of tire aging; after five or six years of use, the rubber hardens and becomes brittle, developing fine cracks upon touch. Even if the tread isn't worn thin, replacing them at this stage is the safer choice. Seasonal changes are crucial too—I switch to winter tires in the northern winters and back to regular tires in the summer for safer and smoother driving. In daily maintenance, I regularly check tire pressure and appearance, heading to a professional shop immediately if any issues arise. After all, tires are the car's feet, and taking good care of them ensures safe travels.
