Can't just retube that

[fatjay]

I'd put the tube inside of the tire after 1st bead is on, add a "little" air (just enough to give it a soft form), then careful not to pinch it, put the second bead on ...

That's what I ended up doing, took it back off, then put hte tube in, air, then back on.

I think you learned a lot about mounting a tire

But the c-clamps might scratch the paint!

They werent' tightened down, just hooked. I was thinking about regular rims, I would say furniture pads would probably work on the c clamp.

I did! And now I can say I've done it.

But guess what doesn't work!

I just had a new 600-16 front tire put on my rim yesterday; no way I'd wrestle with it myself @ 83. The new 600-16 6 ply tire was $117 including taxes, they used my old tube saying it appeared like new.
When I DIY years ago I did as Shawn said with one exception; after mounting you aired the tube to perhaps 20psi then let it deflate. Do that 2x to insure there's no wrinkles or folds, then air up to sidewall pressure.
Pinching a new tube is a bummer, patching it is humilitating.
