1. Make sure that the tire doesn't have a lot of pressure in it. Remove the foreign object with pliers or a screwdriver.
2. Use the file tool in the kit to enlarge and clean out the hole.
3. Take one of the plugs out of the package. If it is cold it will help to warm the plug up using your exhaust if your car is running. Slip the plug half-way through the eyelet on the insertion tool. It may help to put a little of the rubber cement on the plug to lubricate it.
4. Now you are ready to insert the plug. Lubricate the entire plug with the cement. Press firmly and insert the plug until half of the plug is sticking out of the tire.
6. Trim off the excess plug so that it is just above the level of the tire with a razor blade.
7. Inflate the tire and check the air pressure on a regular basis.
Note: If it is difficult to locate the hole in the tire use water and soap if available to find the hole by looking for bubbles. If this isn't possible then inflate the tire until you hear the leak.
