Can a tire be repaired if it's punctured on the side?

A tire cannot be repaired if it's punctured on the side. The reasons why sidewall damage is difficult to repair are: 1. The sidewall undergoes deformation each time it contacts the ground during rotation, commonly known as the surge phenomenon; 2. The sidewall has very few reinforcing cords, lacking sufficient strength, making it impossible to install plugs or mushroom patches. Any applied patches would eventually peel or break due to constant flexing. The main functions of a tire include supporting the vehicle's entire weight, bearing the car's load, transmitting traction and braking torque, ensuring grip between the wheel and road surface, absorbing shocks and impacts during driving, protecting vehicle components from severe vibrations and damage, adapting to high-speed performance while reducing noise, and ensuring driving safety, handling stability, comfort, and fuel efficiency.
Every time I encounter a sidewall puncture, I remind myself that it cannot be repaired because the sidewall is the most vulnerable part of the tire, bearing the weight of the vehicle and impact forces. Once it's damaged, even if a tire plug or hot patch temporarily seals it, the pressure concentration point can cause deformation or even bulging, posing an extremely high risk of a blowout at high speeds. Safety first—pull over immediately upon discovery, switch to the spare tire, and head straight to the repair shop for a new one. Regularly inspect tires for cuts or cracks, and avoid scraping against curbs or running over sharp objects. Developing good driving habits, such as slowing down over bumps, can significantly reduce the chances of damage.
