first off, i used rubber balls instead of a football because of price difference. $3.50 vs $10-$14. what you see here is what is left over after cutting out the valve housing.



that is the valve housing. that is what you want to cut out without destroying the valve.



carefully cut open the valve housing to expose the valve and remove it.



this is the valve. you will notice the the short flat end and long, rounded end. you will be inserting the flat end into the hole you carve or reem out of the rim.



ensure you remove the the coating and ruff up the surface where the plug and the valve will be glued to. when making one of the two stock vent holes in the rim bigger for the valve, use a dremel and increase hole sizeto about 3/4 the diameter of the valve as allow a snug fit.



this is what the valve will look like once it's fully seated and glued into place. apply the glue after you have the valve seated and apply light pressure until the super glue is set, ensure glue is applied under the lip of the valve where it meets the rim.



once you have the valve and the plug (screw or item of your choice) are glued in, slide the tire over the valve. then seat and glue the bead of the tire to the rim ensuring you have a uniform bead of glue. then, moisten a needle inflater tip (used to inflate sports balls) without the hand pump atached so you can gently squeeze the air out of the tire. while the tire is "deflated", pull the needle tip out and leave tire to set. if the tire re-inflates, there is a leak. to find the leak, inflate the tire and put a little water on the tire bead area and roll the tire, moving the water accross the bead, the leak will show up with bubbles.



after all leaks are sealed and tire is inflated, it shouldlooke like the tire on the left, vs. the still foam framed tire on the right.
