Repair a flat using a patch or plug Repair a flat using a patch or plug The activity involves repairing damage to the tread part of the tire. Damage is usually incurred via nail, screw, tack puncture, etc. It is important to note that the only acceptable method of repairing a tire is via the patch method, not the plug method. The plug is a secondary method to fix a puncture. Before trying themselves, students will have been given some theory and the instructor will have demonstrated the proper procedure for repairing a tire.
