Getting a nail stuck in your tire ranks high on the list of the most inconvenient things to happen to your car. The nail often will just stay in the tire, causing the tire to slowly lose air until it goes flat. If you don't repair the tire, you will end up having to get a new one. Luckily, repairing a tire with an embedded nail can be done at home with the right tools and equipment, saving the money it would cost for a repair at a service station.
Locate the nail in the tire. You might need advance the car a few inches at a time until you spot the nail.
Pull out the nail with pliers. Stab the tire with the spike-shaped rasp to open the size of the puncture and get through the entire tire. According to CarsDirect.com, you need to stab the tire a few times to clean the hole out.
Place the black cord halfway through the needle-like spike. Cover the cord with as much rubber cement as possible.
Place half of the needle into the tire so the cord enters the hole. Pull the needle out quickly so the cord gets stuck in the hole. There should be some cord hanging out of the tire. Cut the excess cord away with a razor so it is even with the edge of the tire.
Re-inflate the tire with the air compressor. Make sure you don't overfill the tire.
