How To Tackle A Subaru Tire Puncture

Punctures in car tires are a common problem for drivers, but it’s also an easy one to fix. Learn how to use sealant and what tools you need to get the job done right.

Before You Fix

Before you attempt to fix your car’s tire, you should make sure that:

  • You have the correct equipment and materials on hand (we’ll discuss this later)
  • You have enough time

Identify the Sharp Object

Before you begin, inspect your Subaru tire to identify where exactly the puncture is. You should be able to spot a piece of metal sticking out of your tire. If you can’t see anything, check the treads: if they’re flattened in one area and not another, it’s a good sign that there’s something wrong with your tire. Use a flashlight to get an up-close look at where the puncture is located; once you’ve found it, use a wire brush or sharp object (like scissors) to remove any debris around it so you can better see what needs fixing.

Remove the Sharp Object

Here’s how to remove it safely:

  • Gently pull the sharp object, such as a nail, up and out of the tire, keeping as much of it as possible in view
  • Use your pliers to grip the shank of the nail head (the part that was inside of your tire) and twist it clockwise until you can’t anymore, then stop turning
  • Gently pull on your pliers while pushing down on them with another set of pliers or a wrench. This will loosen up any remaining pieces that are stuck inside
  • If there are still pieces remaining, repeat steps 1 through 3

Push Up the Valve Stem

If you’re using a tire iron or a hammer, push the valve stem up until it hits the rim of the wheel. This should be easy to do if you’re dealing with a slow leak, but may not be so easy if your tire has been punctured more than once and there’s no air left in it. If this is the case, use a screwdriver or pair of pliers to pry up on the valve stem until you can push it through all of its parts. Use caution: these tools are sharp!

Seal The Hole

First, you need to find the tire puncture. Most tires have a small hole or tear in it that can be seen by looking at the tread. Often, this is located on the side wall of your tire—the part of your tire that extends out from its centerline and connects with your wheel rim. If you’re not sure where it is, look at an online diagram or check with a technician about where you bought your car before looking at yourself.

Cover With Electrical Tape

To create a seal, take a piece of electrical tape and wrap it around the tire. The tape should be long enough to cover the puncture hole in your tire. If you don’t have any electrical tape on hand, you can use duct tape or painters’ masking tape instead.

Once the length is right for your particular tire, slide it into place over the puncture hole inside your tire’s sidewall until it comes into contact with both the inner and outer walls of the tire.

Clean Your Hands

Take off your gloves, then put them away and wash your hands thoroughly with soap and water. Wash all parts of your body that may have come in contact with the punctured tire or any other potentially contaminated surfaces.
