So here’s a question I’ve been meaning to ask for while regarding bicycle tire bead mounting tools (and the OP’s fabrication is outstanding BTW). I have one of those pivoting plier-style tire mounting tools that I’ve really only used a few times. But here’s the thing. Once you get that extremely though-to-mount tire ON…and then you get a flat mid-ride, and the tool is back at the house…how do you get that very tight tire OFF…and then back ON when you’re roadside? I just went through this drill in the garage with new tires (Panaracer Stratus Sport 700x23 folding) that are so tight that getting the first bead on the rim was difficult. I got the second bead mostly on. But there was just no way that last six inches was/is going over the edge of that rim. (I’ll be getting different tires.) And if I did get it on…that’s when I thought there’s no way I’d get it off, nor back on, roadside.
