Hold the valve stem in place with your finger until you can secure it to the valve stem tool. There is only one hole through the rim so it should be easy to find.
If the tool is not threading on properly, unscrew it and attempt to screw it on again. Hold the valve stem from the other side with your finger so it doesn’t rotate with the tool.
You may want to place a rag beneath the handle of the tool on the lip of the wheel to protect its finish. You may need to apply a good deal of pressure in order to wedge the valve stem in the hole properly.
The bottom ring should be seated firmly against the inside of the wheel. The top ring should be on the outside of the wheel, holding it securely in place.
Don’t apply too much pressure when testing the valve stem or you may push it back through the hole.
Use a tire iron or socket wrench to break the lug nuts loose on the wheel prior to jacking up the vehicle. Place a jack stand beneath the vehicle to support it while you work on the wheel.
If you misplace a lug nut, you can purchase replacements at your local auto parts store.
Lay the wheel down on the ground face up so the valve stem is toward the sky. Do not strike the wheel itself as you may damage it.
You may want to wear gloves to prevent the air escaping from being too cold on your hands. You can also use a screw driver or similar tool to release the air.
You may need to apply a good amount of pressure to get the tool past the valve stem. Be careful not to scratch the finish of the wheel with the valve change tool.
Try to pull straight outward from the wheel to avoid chipping the finish.
You can purchase valve stem replacement tool kits at your local auto parts store. The insertion tube will guide the new valve stem as you press it into place.
You can purchase tire sealant lubricant at your local auto parts store. You may be able to insert the valve stem without lubricant, but the seal will be stronger if you use it.
You will need to thread the valve stem onto the insertion tool so you can pull it back up once inserted. You may need to apply a good deal of pressure to get the stem through the hole.
If you accidentally pull the stem all the way back through, repeat the process to reinsert it. You can now refill the tire and place it back on the vehicle.
