Can a nail puncture on the sidewall of a tire be repaired?

[HenryLee]

Tire puncture on the sidewall should be judged based on the location of the nail puncture and the extent of damage to determine whether the tire needs to be replaced or repaired. If the nail punctures the tire crown, as long as the nail is not too thick, it can be repaired at a professional repair shop. The most effective repair method is using a mushroom plug. However, if the nail punctures the tire sidewall, it cannot be repaired and must be replaced. For a puncture on the tire sidewall, replacement is the best option. The sidewall is the weakest part of the tire, consisting of two layers of rubber and two layers of cords. To reduce vibration, passenger car tire sidewalls do not have a steel belt layer. Additionally, the sidewall undergoes continuous deformation and recovery during rotation. Forcing a repair may cause the patch on the sidewall to fall off. Even using a hot patch method only provides a temporary solution, as broken cords cannot be repaired.
