Puncture repair is the process of fixing a hole or tear in an object, commonly associated with tires. When a tire gets punctured, it can lose air pressure, leading to poor performance and safety issues. Repairing a punctured tire typically involves locating the hole, cleaning the area, and applying a patch or plug to seal it. This repair can be done at home or by professionals at a tire shop. It's important to assess the damage; some punctures, especially those on the sidewall, may require a complete tire replacement for safety reasons. Regular maintenance can help prevent punctures.
