Can a damaged area next to the tire be repaired?
2 Answers
Puncture holes with diameters less than 6mm can be repaired. Tires cannot continue to be used under the following circumstances: 1. The tire is worn out. Tires have tread wear indicators with a height of 1.6mm (the legal minimum groove depth). Using worn tires on wet or slippery roads may lead to hydroplaning, increasing the risk of losing control of the vehicle. 2. The tire is damaged. Hitting curbs, falling into potholes, or having nails inserted can severely damage tires. Damaged tires may be repairable, but only a professional repair shop can accurately determine whether the tire can be repaired or needs to be replaced. 3. The tire is aged. If tread deformation or significant cracking is observed, stop using the tire immediately and have it inspected by a professional repair shop to determine if it can continue to be used. 4. The tire has a bulge. Tire bulges are a high-risk factor for blowouts, especially on highways. Tires with bulges should be replaced promptly.
If there's damage on the sidewall of a tire, it's generally not recommended to repair it. Having driven for over twenty years, I've seen too many similar cases—the sidewall is thin and bears significant force, making repaired punctures prone to air leaks or even blowouts, especially during high-speed driving or on curves, which poses too high a risk. Once, I noticed a small scratch on the sidewall and took it to a repair shop for inspection. The technician immediately shook his head and said it couldn't be fixed—only replaced. I'd rather spend a few hundred more on a reliable new tire than take the risk. Safety first, after all. I regularly check my tires' condition and pressure and avoid potholes to prevent damage.
