One more tip: (if you didn't buy a Bead Jack based on this thread)
Most folks avoid tire irons during installation to prevent pinch flatting the tube. If you have a really tight set of tires, first mount them up without the tube, using tire irons. No risk of pinch flatting, and the process of mounting stretches the bead a bit. Then stuff the tube in after it sits for a while. It's usually much easier to mount a tight tire the second time around.
