I agree about the tools, but I did it with the Harbor Freight tire machine the times that I did it, so it is possible.
I talked to the service manager at Triumph of Chattanooga right after I got the Rocket about the rear tire and balancing, he told me that the tire machine they had would not accept the rocket rear wheel due to it's width so they didn't balance them when they changed them.
I've never balanced a bike tire and have never had a problem front or rear, no cupping nor uneven wear. I do balance the bare wheel though and it is usually out of balance when they are first checked. Of course I don't ride at speeds much above the posted limits so I really haven't tested the effects at much over 85-90 MPH. But below that, if you align the dot on the tire with the valve stem most times the tires are fine. I have had to break the bead and move the tire a little a couple of times but it is rare. This is just me though I can't say that I recommend it to anyone else.
Oh and I did use the Dyna beads on the Toyo, didn't really notice a difference.
