How to Take Out the Valve Stem of a Tire

Valve stem with cover on

A valve stem is a spring-loaded device that helps keep air in your tires. The valve stem has a small attachment that allows air to enter when pressed, for when you need to inflate your tires. Valve stems wear out over time and usually require replacement around the same time as your times. A worm valve stem can cause your tires to deflate.

Things You'll Need

• Needle-nose pliers
• Replacement valve stem
• Air compressor

Instructions

1. 

   Make sure you have access to an air compressor prior to removing your valve stem. Once the valve stem is removed, the tire will lose air quickly and require inflation.

2. 

   Engage your vehicle's parking brake for safety. Twist the valve stem cover counterclockwise to remove it.

3. 

   Look inside closely to find the valve stem. You will be able to see a small point, as shown in the photo.

4. 

   Use the needle-nose pliers to pull the old valve stem out. With a little bit of force, it will come out easily.

5. 

   Replace the valve stem with a new one. Apply a small amount of water around the new valve stem and use the pliers to insert it until it locks.

6. 

   Re-inflate the tire to the recommended factory PSI (check your owner's manual).

Tips & Warnings

• There is a special tool you can purchase to help you remove the valve stem. In most cases, a pair of needle-nose pliers works very well. Check with your local auto parts store if you are interested in such a tool.

• Do not attempt to drive your vehicle without a valve stem--it will not hold air longer than a minute or two.
