A tire comes with a valve stem pin that operates to both inflate and deflate the tire. Releasing air from a tire happens when the pin is depressed. A faulty valve stem pin needs to be replaced to ensure that the tire maintains the proper air pressure. Valve stem pins are available at auto parts stores. Removing and replacing the valve stem pin should always be done wearing safety glasses.

Place the valve stem tool on the valve stem. Screw the tool onto the stem.
Press down on the tool after it has been screwed on. By pressing down on the tool handle, the valve stem will pop out. If the valve stem breaks into two pieces, remove and discard the pieces.
Take the new valve stem pin and place through the hole in the rim. Thread your tool onto the valve stem.
Bend your tool down so one of the lines on the tool is matched up to the edge of the rim. Continue to pull the tool up and down, using it as a lever. Each time you pull the tool up and down, you will pull the stem higher and through the hole in the rim. Continue doing this until the bottom ring of the stem reaches the inside of the rim. The top ring should reach the outside of the rim.
Remove the tool by unthreading it from the valve stem pin. Check that the valve stem pin is properly installed by making sure that the stem has a snug fit and holds air.
