How to Repair, Plug & Patch a Tire

A flat tire due to a nail or screw can be a frustrating experience---especially on a tire with only a few miles on it. Instead of replacing the tire, purchase a tire repair kit and fix the tire yourself for a fraction of the cost. A properly installed plug patches the hole and seals the puncture sufficiently enough to re-establish an airtight seal and get you on your way.

Things You'll Need

  • Car jack
  • Tire iron
  • Screwdriver
  • Pliers
  • Tire repair kit
  • Clippers
  • Jack up your vehicle using your car jack. Loosen the lug nuts with the tire iron, and remove the tire. Keep the vehicle stable during this process.

  • Inspect the tire to locate the object causing the tire to go flat. If the object is a screw and the head remains undamaged, remove it with a screwdriver. If the object is not a screw or the head has sustained damage, pull it out with pliers.

  • Open the repair kit and locate the rasp tool, which resembles a round file. Insert the rasp into the puncture, turning it clockwise until you have fully inserted it. Leave the tool in the hole.

  • Locate the plugs in the repair kit, and remove one. Locate the remaining tool in the kit, which resembles a large needle with an eye. Pinch one end of the plug, and thread it halfway through the eye of the needle.

  • Pull the rasp tool out of the tire, turning it clockwise. Immediately insert the eye of the needle tool, and thus the plug, into the hole.

  • Push the tool into the tire, turning it clockwise, which will require some force. When 1/4 to 1/2 inch of the plug remains outside the tire, pull the tool out. The plug will remain in the tire with two ends protruding out.

  • Clip the ends of the plug with your clipper so they lie flush with the tire's tread.

  • Inflate the tire to the recommended specifications. Mount the tire onto the car, properly tightening the lugs nuts with your tire iron.
