How To Use A Tire Plug Kit The Right Way

Learn how to use a tire plug kit for the next time you need emergency repair on the road.

Flat tires tend to happen at the worst time in the worst places. If you are on the road or outside of normal business hours when your vehicle has a flat and the spare is missing or no good, you might feel stranded, but there is an option—a tire plug kit. This is something that anybody can do, you just need the right parts.

Liquid tire repair might get you down the road, but it could make your tire repair difficult and possibly damage the TPMS (Tire Pressure Monitor System) unit inside the rim itself depending on the formula. The best solution for an emergency tire repair is a tire plug. Made from cork and a gooey adhesive that keeps it place and seals the tire, a tire plug repair is an excellent way to get your car back on the road until you can get to a tire shop for a proper internal patch.

Installing a plug in your tire works for pierced tread area only. You cannot fix sidewall damage, compression breaks (from potholes, gravel roads or curbing) or any other type of catastrophic tire damage. The most common road hazards you will find are punctures from nails and screws. Fixing these issues are perfect for the good old fashioned tire plug. If you are wondering how long does it take to plug a tire, then the answer is just a few minutes. Most of the time is spent preparing to perform the plug itself. Here’s how to plug a tire with a plug kit.

Tire Plugging Supplies

You will need the following to make a tire plug repair:

There are all kinds of tire plugging kits, but you want the most complete tire repair kit which comes with the plugs, the installation tool, and the reamer tool. Some flat tire repair kits just come with the plugs and installer, but the reamer tool is a necessary component to a good repair. Some tire plugging kits also come with liquid cement. You can use it or not, but the cement helps make a more permanent repair.

How To Use A Tire Patch Kit

Step One – Find The Leak

Locate the puncture. If you don’t see or hear the puncture, spray some soapy water on the tire and look for bubbles.

Step Two – Remove The Foreign Object

Remove the offending item. This is usually easy, but sometimes the nail or screw is worn down, making it hard to get a bite on it. This is where the side-cutters come in really handy. You will want to position the tire where you get the most leverage.

Side cutters work best for removing these items, as they can grip small round objects better than regular pliers.

Step Three – Prep The Area

Insert the reamer. This will take some effort, as you have to push it through the steel belts. Use a twisting motion and push it into the tire. Once the reamer is through, saw it in and out of the tire a few times to really make a nice hole for the plug. Yes, it is counter-intuitive, but it is necessary.

The reamer requires some effort. You will hear the belts scrubbing the reamer as your break through.

Step Four – Prepare The Plug

Prep the plug and installer. Pull a plug off the strip and push it through the eyelet of the installer tool. The pliers will make this easier. Push a little through, grab it with the pliers and pull the plug halfway through the eyelet.

Threading the sticky cork tire repair plug is not easy, but if you can get it squished into the hole, you should be able to pull it on through. The side cutters might help.

Step Five – Insert The Tire Plug

Insert the plug into the tire. If the kit has liquid cement, apply some to the plug before inserting it into the tire. Simply push the installer into the hole in the tire until the plug is about 3/4 of the way in. Twist the installer tool 90-degrees and pull it out. The plug will stay in the tire and the tool will come out nice and easy. You may trim away the excess plug or leave it to wear away as you drive.

Push the tire plug into the hole. Don't twist the plug as you push it in, just go straight down and stop when there is about a 1/2-inch exposed.

Step Six – Air Up The Tire

Fill the tire to the proper PSI. If you have a portable air compressor, this will make things easy. However, if you do not, you need to get air very soon.

All done. You can trim the tire plug or leave. You will need air, so don't go driving until you have the tire aired up.

They will know the best way to patch a tire for your type of damage.
