Step 1: Determine if the tire is repairable. Any puncture that is in the sidewall or shoulder of the tire should not be plugged.
Step 2: Remove the object from the tire using a set of needle nose pliers or screwdriver. Always wear safety glasses!
Step 3: Insert the rasp tool into the puncture. Work the tool up and down to rough up the hole.
Step 4: Install a plug on the plug insertion tool. Make sure that there’s roughly half of the plug on each side of the tool.
Step 5: Apply rubber cement to the tire plug.
Step 6: Push the tire plug into the puncture hole until there’s 3/4″ of the plug remaining on the outside of the tire. Pull the plug insertion tool straight out in one motion. This will leave the plug left in the tire.
Step 7: Cut the plug off so that it’s flush with the tire tread.
Step 8: Refill the tire’s air pressure and check for leaks at the plug with a soap and water solution.
