My tire changes have modified since I got the Rocket. I chrome plated my rims. I now use the internal beads for balancing. After fighting the drive splines, I changed to balancing the rear tire on a floor jack. Sliding the floor jack into position then jacking up to location of the splines is simple. Don't ram and jam just take it slow and easy. Doing the front is done the same. Balance the tire/wheel on the jack. Slide between the forks, jack up to location. I don't change the tires, due to fear of scratching my rims and being lazy.
