I.D bead width....this will not hold the solid tire secure. I will have to find some way to press the rim inwards a total of about 5 -6 m.m so its inside bead lip will grab the solid tire adequately....I have the tire installed on the rim right now...im thinking I may be able to take it to a machine shop and let them use a hydraulic press that can accurately measure 6 m.m of compression on the rim { 3 m.m for each side] so the inside bead lip grabs the bead of the solid tire.
I believe the machine shop is going to have to build a custom jig to do that which will cost a good bit.
Go to the bike shop and have them show you how to properly install tape, tube, and tire.
Or failing that, have them lace you a new rim that will fit your solid tire. I think it will be a better outcome than mashing your rims in a vice.
