Don't ask for pictures; I can't do them.
I have changed numerous LR-E DRW and SRW wheels/tires on my simple Harbor Freight tire-changer --- and I have access to a complete tire-shop full of the latest air- and electric-driven changers, Coats, Hunter, Corgi, Ranger, etc.
Trick #1 is BOLT the changer down to the floor.
Trick #2 is drill through the changer "table" and bolt an old 8-lug brake-rotor through four of the holes with extra-long bolts, such that there is sufficient thread-length remaining above the nuts that hold the rotor onto the changer to mount the wheel onto the remaining threads and secure it with four nuts.
Bolting the wheel to the brake-rotor is a lot more secure than trying to use the little four-legged gizmo that is supplied with the changer.
There is a many many paged discussion on the Harbor Freight changer at the tractorbynet site.
All that being said, I have changed countless tires with nothing more than a couple of flat-ended crow-bars or tire-irons or whatever was available at the time.
