Final answer:
To fix a tire puncture, you use pliers to pull the repair plug through the hole until the patch is flush with the tire wall, ensuring a proper seal and tire performance.
Step-by-step explanation:
To pull the plug from the outside of the tire through the tire hole, you firmly grasp the plug with a pair of pliers and apply steady force to feed it through the hole. This process is a common method used in tire repair to seal punctures from the outside. Once inserted, you must continue to pull the plug until the patch is flush with the tire wall, ensuring it's properly seated and that it will prevent air from escaping from the tire. The goal is to make sure that the patch is neither protruding from the tire's surface nor sunken in too deeply which can interfere with the tire's performance.
