How to Replace Valve Stem
1. Identify whether or not the valve stem to be replaced has a TPMS. These valve stems will not fit the wheel with TPMS.
2. Identify whether the valve stem to be replaced is a high pressure valve stem.
3. Deflate the tire.
4. Before inserting the valve stem, you can lubricate it.
5. Push the old valve stem through the rim and remove the valve stem from the wheel.
6. Choose which one of the black rubber grommet you need. Insert the new metal valve stem from inside the rim and pull through until the rubber grommet is seated.
7. Seat the tire and inflate.
