Can a Nail Puncture in the Tire Sidewall Be Repaired?

[GenevieveMarie]

The sidewall of a tire cannot be repaired if punctured by a nail. The sidewall is the weakest part of the tire, constructed with two layers of rubber and two layers of cord fabric. To enhance shock absorption, passenger car tire sidewalls do not include a steel belt layer. Additionally, the sidewall undergoes continuous deformation and recovery during rotation. If a repair is forcibly attempted, the adhesive patch on the sidewall may detach. Even using a hot patch method only provides a temporary fix, as broken cord fabric cannot be restored. Tires are circular elastic rubber products mounted on various vehicles or machinery to roll on the ground. They often operate under complex and harsh conditions, enduring various deformations, loads, forces, and extreme temperatures while driving. Therefore, tires must possess high load-bearing capacity, traction performance, and cushioning ability.
