To break the bead I use a large C-Clamp and a piece of 2x4 . Hold the 2x4 under the wheel and on the rim , place the top of the C-Clamp on the 2x4 and the bottom ( the screw) on the top of the tire as close to the rim as you can and just turn the screw till it breaks the bead . Im thinking of having a piece welded on the screw end of the C-Clamp so there is a little more surface on the tire . Then with 2 tire irons the rest is easy . I also use a ratcheting strap around the tire to help push the bead out till it starts to hold air .
As far as balance . I tried and love the balancing beads you put in the tires . Check out Innovative Balancing their product is called Dyna Beads . They really give a smooth ride and they have a chart on how much to use in each tire . No need to do any balancing with them .
