Can a small chunk missing from the tire sidewall be repaired?

[DeArcher]

Tire sidewall damage or air leakage cannot be repaired and requires tire replacement. The reason is that according to tire structure, the sidewall is the weakest part, consisting only of thin rubber layers and cord plies. These cord plies are mesh layers woven from cotton threads and rayon, bearing the air pressure that supports the entire vehicle's weight. If the tire sidewall is cut, especially when the cord plies are damaged, it completely disrupts the structural stress of the sidewall, making tire blowouts highly likely. Here are tips to avoid sidewall scratches: 1. Slow down when passing: Reduce speed when driving over potholes, speed bumps, or other uneven road surfaces. 2. Avoid two excesses: No speeding or overloading. 3. Avoid abrupt actions: Avoid sharp turns, rapid acceleration, emergency braking, and curb scraping.
