After you have the spoke attached, you can go ahead and put the rim tape back over the spoke nipples.

After you put the rim tape back on, you can go ahead and reattach the tire and tubing.

You need to put the tire on first and then by lifting up one edge of the tire slide the tubing back inside of the tire. Make sure to match up the filling hole to the hole in the rim so that you will be able to inflate your tire

Be careful not to put the tubing in kinked because that will effect how it inflates.
