Can't just retube that

You need to keep the tire pushed down off the lip of the wheel so it’s in the middle section of the wheel. That way it can move quite a bit from side to side and allows you to roll the bead over the wheel rim without actually stretching the tire.

You need a helper or a clamp or something to push the tire down at about the 6 o-clock position. If it’s down and off the edge of the rim you’ll be able to roll the rest of it into place.

Wish I could explain it better. But the tire bead can’t be in its final position until the tire is completely mounted. They really don’t stretch overall. Need to allow the whole tire to move directionally as you work it onto the rim. The bead OPPOSITE where you're prying can't be "set" -- must be pushed down on the wheel where the diameter of the rim is much less and the tire can move in the direction that you're prying.

Edit -- In other words, pay close attention to the opposite side from wherever you're prying. In order to work the tire bead over the edge and onto the rim, you have to keep the OPPOSITE side pushed down into the belly of the wheel so the whole tire can shift your direction a bit and allow it to roll onto the rim.

I'm sure you're using a lot of lube. That's also key.

Nice job o

I'll take a pass at this. As you're pulling one lip over the edge of the rim, both opposite edges of tire (upper and lower) have to be sucked into the middle of the rim - It is a smaller diameter, and it gives you some "slack". Put a brick at the edge of the wheel on the back side to hold the tire up slightly, and push the top side down slightly (so both tire edges are sucked into the middle of the rim), and with your third arm, stretch the tire over the rim.

I made a couple of changes on my HF mounting bar.

I lengthened mine, so it is now 5' or 6' long. A little extra leverage helps.

I also added a piece of square tubing down near the place where it rides on the rim to help keep it from rolling.

Make sure you soap up the tire.

You have a tube so setting the bead shouldn't be a problem. Just be careful not to pinch the tube under the bead. On the other hand, for tubeless, I like to put a bicycle tube 16" or 20" or so, around the gap to help keep the air in and seat the bead. Once I begin to get the bead seated, I pull the tube out of the way.

We used to have a couple of pieces of leaf springs with rounded corners and beveled edges that we used as tire irons,

Cleaned up the inside, went to mount the tube, and it was the wrong size... Completely ruined my motivation for the evening.

I've read of some guys using the old tube to make a rim liner. They cut it in half circularly, and use the inner half.
New rim liners are are sold for 26" tires down.
