I have made progress. here is what i used for the first tire: super glue, 2 spare screws, a rubber "dodge ball", and a dremel.

i used one of the screws to seal up one of the two stock holes in the rim. then i carefully cut out the valve from the dodge ball. after inspecting the valve, i reemed the other hole in the rim so that i could snugly insert the valve so that it would be inside the tire once the tire was sealed up. then i applied super glue around the valve to seal it up to the rim. after the glue was dry and set. i closed up and sealed the tire with super glue. again after the glue was dry adn set, i took a sports ball inflater pump with the needle and moistened it and pressurized the tire. i found all the leaks by putting a little water where the rim met the tire and rolled the tire around to watch for bubbles. when you find a bubble, deflate the tire so it has "negitive pressure" and applied some super glue and watched the tire soak up the glue where the leak was. after all leaks are sealed, inflate tire to desired pressure and insert the other screw into the valve to plug it.

pictures to follow as i finish the other 3 tires.
