I use a clip on air chuck, and no valve stem. I put the tire out in the drive, turn on the air from in the gurage, and run it up to the bead seating pressure listed on the side wall. I hear the pop-pop of the two beads setting, then I release the air. Put in the valve stem and all done.
Soap helps a bunch too.
