If you can break the bead without removing the wheel you can do this on the bike. I could not, and had to remove the wheel/tire. I did not remove the tire.
1. Bust the bead, cut the rubber stem off, be careful not to drop the inside piece of the rubber stem inside the tire. I used a small screw driver to guide it to safety.
2. Insert the rubber seal and metal valve stem, turning it clockwise and a little silicon makes it easier.
3 Make sure it faces the right side of the wheel, install the nut using a 14mm socket. It will bottom out when tight.
4. Inflate the tire.
