Can Vacuum Tires Be Repaired?
2 Answers
Vacuum tires with small rupture areas can be repaired, but the repair cost is relatively high. Below is the relevant information: Introduction: Vacuum tires with puncture diameters less than 6mm on the sidewalls can be repaired. For some smaller sidewall damages, since the cord layer is not severely damaged, they still have repair value, such as small holes caused by sharp objects piercing the tire side. Vacuum tires with missing or cracked side rubber but no leakage can also be repaired. If the tire is not leaking, shallow rubber loss or cracks on the tire side can be repaired. Precautions: Although minor damage to the tire sidewall can be repaired, the repaired tire loses its original durability and safety and can no longer serve as the primary tire. For safety reasons, repaired sidewall tires should only be used as spare tires.
I've encountered situations where tubeless tires got punctured by nails and found that they can actually be repaired. The most common method is to remove the tire, clean the damaged area with a grinder, then insert a mushroom plug or apply a patch from the inside to seal the leak. However, location is crucial—only punctures in the middle of the tread area can be reliably repaired. If the puncture is near the shoulder or sidewall, even a repair might not hold. Once, my tire was scratched by a small stone, and a professional mechanic fixed it with a mushroom plug. After the repair, I drove over 20,000 kilometers without any issues. Remember, during the repair, it's essential to ensure no debris remains inside, as poor sealing can lead to leaks again. Although the process is technical, an experienced repair shop can usually complete it in about 20 minutes, which is more convenient and cost-effective than replacing the tire. Regularly checking tire pressure and maintaining your tires can help prevent unexpected damage.
