Tires are an essential part of any vehicle, and a flat tire can be a real hassle. One of the most common causes of a flat tire is a nail puncture. While it may seem like a daunting task, fixing a tire with a nail in it is actually quite simple if you know what you are doing.

What You Will Need

Car ToolsSource:

Before you begin, make sure you have the necessary tools and materials. These include:

  • Tire repair kit
  • Tire pressure gauge
  • Jack
  • Lug wrench
  • Valve stem tool
  • A spare tire

Determine the Location of the Nail

Tire NailSource:

The first step in fixing a tire with a nail in it is to locate the nail. This can be done by visually inspecting the tire or by using a tire pressure gauge to identify the punctured area. If you notice a nail or any other sharp object lodged in the tire, do not attempt to remove it just yet. Instead, mark the location of the puncture with a piece of chalk or a marker.

Remove the Nail

Once you have identified the location of the nail, it is time to remove it. Use pliers or a pair of needle-nose pliers to grasp the nail firmly and pull it out of the tire. Be careful to avoid further damaging the tire.

Assess the Damage

Tire DamageSource:

Inspect the punctured area and check for any signs of damage. If the nail has caused a small hole or puncture in the tire, it may be possible to repair the tire. However, if the damage is more severe or the sidewall is punctured, the tire may need to be replaced.

Repair the Tire

Tire Repair KitSource:

If the damage is repairable, use a tire repair kit to patch the punctured area. Follow the instructions that come with the kit to ensure a proper repair.

Use a Jack to Lift the Car

Car JackSource:

Before you can repair the tire, you will need to lift the car using a jack. Position the jack under the car frame near the tire that needs to be repaired. Use the lug wrench to loosen the lug nuts on the tire. Make sure not to remove them completely.

Remove the Tire

Once the lug nuts are loose, use the jack to lift the car off the ground. Remove the lug nuts and carefully pull the tire off the car. Place the tire on a flat and stable surface.

Locate the Puncture from Inside the Tire

Tire Puncture LocationSource:

Locate the puncture from the inside of the tire by running your hand along the inside surface. Once you have located the puncture, use a valve stem tool to remove the valve stem from the tire.

Clean the Puncture Area

Tire CleaningSource:

Before you can repair the punctured area, it is important to clean it thoroughly. Use a wire brush or sandpaper to clean the area around the puncture. This will help to ensure a better seal when you apply the patch.

Insert the Repair String

Tire Repair StringSource:

Take the repair string from the tire repair kit and insert it into the punctured area from the outside of the tire. Push the string in until it is about halfway through the puncture.

Apply Rubber Cement

Rubber CementSource:

Apply a small amount of rubber cement to the repair string. This will help to seal the punctured area and prevent air from escaping. Be careful not to use too much rubber cement, as this can cause the patch to fail.

Insert the Repair String Completely

Tire Repair KitSource:

Push the repair string the rest of the way into the puncture. Use a pair of pliers to pull the string out quickly and smoothly. This will help to ensure that the repair string is seated properly.

Trim the Excess Repair String

Tire Repair KitSource:

Use a pair of scissors to trim the excess repair string from the tire. Be careful not to cut the string too close to the surface of the tire, as this can cause the patch to fail.

Reinstall the Valve Stem

Valve StemSource:

Reinstall the valve stem into the tire using the valve stem tool. Make sure the valve stem is seated properly and tightened securely.

Reinstall the Tire

Reinstalling TireSource:

Place the tire back onto the car and tighten the lug nuts by hand. Lower the car back onto the ground using the jack. Use the lug wrench to tighten the lug nuts securely in a crisscross pattern.

Check the Tire Pressure

Tire Pressure GaugeSource:

Use a tire pressure gauge to check the pressure of the repaired tire. Make sure the tire pressure is within the recommended range for your vehicle. This information can usually be found in your owner’s manual or on a sticker located on the driver’s side door jamb.

Test the Tire

Tire TestSource:

Take your car for a test drive to ensure that the repaired tire is functioning properly. Pay attention to any unusual noises or vibrations, and check the tire pressure periodically over the next few days to make sure it remains stable.

When to Replace a Tire

Replace TireSource:

In some cases, it may not be possible to repair a tire with a nail in it. If the damage is severe or the sidewall is punctured, the tire will need to be replaced. Additionally, if the tire is old or worn, it may be time to replace it regardless of the damage.


Fixing a tire with a nail in it may seem intimidating, but with the right tools and a little bit of know-how, it is a simple process that can save you time and money. Remember to always follow the manufacturer’s instructions when using a tire repair kit, and to inspect your tires regularly for signs of damage or wear.
