What are the situations that require tire replacement?

[VonSadie]

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.

I believe changing tires is mainly to prevent safety hazards, so I take immediate action whenever I notice any abnormal tire conditions. For example, if the tread wears unevenly, with one side wearing faster than the other, it may indicate issues with the axle or suspension. In such cases, I prioritize repairing the vehicle before replacing the tires to avoid wasting money and risking danger. Additionally, if there are deep cracks or hardened spots on the tire surface, these are signs of aging, and failing to replace them promptly could lead to sudden failure while driving. I also check the tire manufacturing date and replace any tires older than six years to prevent unexpected incidents. Furthermore, in areas with harsh weather or challenging road conditions, such as the mountainous regions I frequently drive through, tire damage like cuts or bulges from rocks is common, so I make sure to prepare in advance. In short, safe driving is my top priority, and I’ve developed a habit of performing simple monthly checks to ensure my tires are in good condition.

From my perspective, changing tires is usually based on practical issues. For example, if a tire bursts or has a severe leak that can't be patched, I quickly change to a spare tire by the roadside and replace it with a new one later. Also, when tires wear out over time with treads nearly smooth and braking distance increases, I replace them to improve traction. During seasonal changes, I don't need snow tires in the south, but I switch to tires with good drainage before the rainy season to reduce skidding. Occasionally, if the tire sidewall is scratched or bulged by the curb, I replace it for safety. As an average car owner, I try to save money by choosing cost-effective tires and avoid unnecessary upgrades, only acting when necessary.

I think there are several common scenarios for changing tires. First, tire damage, such as being punctured by sharp objects and unable to be repaired, requires replacement; when the wear is severe and the tread is too shallow, affecting handling, it should be replaced promptly. There is also tire aging, where the rubber hardens after prolonged use, typically needing replacement after about five years. Seasonal changes are another reason—I switch to snow tires in winter to prevent slipping and back to standard tires in summer. From personal experience, checking tires before long-distance or highway driving is crucial. I’ve had a few breakdowns on the road due to uneven tire pressure that wasn’t detected and replaced in time. Additionally, to improve driving comfort, if the tire noise is too loud or vibrations are noticeable, I also consider replacing them. Remembering these small details can save a lot of trouble.
