How to Plug a Tire: A Step-by-Step Guide

Knowing how to plug a tire is a handy skill to have when a nail or screw causes a flat. With a tire plug kit and a few basic tools, you may be able to stop a small leak until you can get your vehicle to a repair shop.

Just remember that not every puncture can be repaired, and a plug by itself is not a permanent fix. Here's a quick look at how tire plugs actually work and how to install one if needed.

What Is a Tire Plug, and How Does It Work?

A tire plug is a flexible strip of rubber-coated material that fits into a puncture to prevent air from leaking out. It's commonly used when a nail or screw pokes a hole in the tread of a tubeless tire. The plug fills the opening and creates a seal that can temporarily restore air pressure.

This can be helpful if you have a flat in an area where roadside assistance isn't easily available.

However, an externally installed plug doesn't address possible damage inside the tire. Professional tire repairs require an internal inspection and a combination of a plug and patch to seal the hole properly. A DIY plug should only be considered an emergency fix until you can have the tire inspected.

What Do You Need in a Tire Plug Kit?

Most tire plug kits contain the basic tools needed to seal a small puncture. The contents may vary, but a typical tire repair kit includes the following items:

• Rubber plug strips: Flexible strips that fill the puncture and prevent air from escaping.
• Reaming tool: A pointed tool that cleans and prepares the puncture for the plug.
• Insertion tool: A tool with a split opening that holds the plug strip during installation.
• Rubber cement or lubricant: Some kits include a compound that helps with installation. Follow the instructions for your particular product.

You'll also want pliers to remove the nail or screw and a tire pressure gauge to check inflation. A portable air compressor is especially useful because the tire will probably lose more air during the repair.

A spray bottle with soapy water can help you spot small leaks and check whether the plug has created a temporary seal.

Steps to Plug a Tire

If you find a small puncture in the central tread, an emergency plug can help you make your way to Performance Tire. Here's how the basic process works.

Step 1: Park Safely and Find the Puncture

Find a level parking area away from traffic. Turn off your engine and engage the parking brake.

Inspect the tread for a nail, screw or other object. If the source of the leak isn't visible, apply soapy water to the suspected area. Escaping air will produce bubbles.

Never attempt to repair a tire if your vehicle is in an unsafe location. If the tire is severely deflated or the damage is too difficult to reach, roadside assistance may be the better choice.

Step 2: Remove the Object

Once you've located the puncture and have the repair tools ready, carefully pull out the nail or screw using pliers. Be prepared for more air to leak out while you remove the object.

If the tire has already lost most of its pressure, you may need to add air before continuing.

Step 3: Prepare the Puncture

Insert the reaming tool into the hole, following the instructions supplied with your kit. Move the tool as directed to get the puncture ready for the repair strip.

This helps create an opening that allows the plug to fit securely. Try not to use too much force, and don't unnecessarily enlarge the hole. If the damage looks too big for the kit, don't attempt to plug it.

Step 4: Insert the Tire Plug

Thread a rubber repair strip through the opening in the insertion tool. If your kit requires rubber cement or another compound, apply it according to the directions.

Push the strip into the puncture to the depth specified in the kit, leaving the recommended amount exposed. Then carefully withdraw the insertion tool, allowing the plug to remain in place.

Step 5: Trim the Excess Rubber

Use a cutting tool to trim the excess plug material according to the kit's instructions. Be careful not to pull the plug loose while trimming it.

Step 6: Reinflate and Check for Leaks

Reinflate the tire to the correct pressure, which you can find on the driver's doorjamb.

Apply soapy water around the plugged area and watch for bubbles. If air is still escaping, the temporary seal hasn't worked.

Even if the tire holds pressure, you should have a professional inspection done soon rather than assuming the repair is permanent.
