Flats tend to happen at the worst time in the worst places. If you are on the road or outside of normal business hours, your vehicle has a flat, and the spare is missing or no good, you might feel stranded, but there is an option- emergency repair. This is something that anybody can do, you just need the right parts.
Liquid tire repair might get you down the road, but it will make your tire repair impossible and it could ruin the TPMS (Tire Pressure Monitor System) unit inside the rim itself. The best solution is a tire plug. Made from cork and a gooey adhesive, that keeps it in place and seals the tire, a tire plug is an excellent way to get your car back on the road until you can get to a tire shop for an internal patch.
Installing a plug in your tire works for pierced tread. You cannot fix sidewall damage or compression breaks (from potholes, gravel roads or curbing). The most common road hazards you will find are nails and screws. Fixing these issues are perfect for the good old fashioned tire plug.
You will need the following to make a tire plug repair:
Tire plug kit
Pliers, preferably needle-nosed or diagonal side-cutters
Compressed air to refill the tire
There are all kinds of tire plug kits, but you want the most complete kit, which comes with the plugs, the install tool, and the reamer tool. Some kits just come with the plugs and installer, but the reamer tool is a necessary component to a good repair. Some kits come with liquid cement, you can use it or not, the cement helps make a permanent repair.
