Removing PVC inserts from H1 tires?

I have a Toyota with recentered H1 8-bolt beadlocks and
I am in the process of dismounting my 37x12.5.x16.5 Wrangler MT's and swapping over to 36x12.5.16.5 Wrangler RTII's and I have PVC inserts in my tires. I can't figure out how to get them out of the tire? I looked online and I found instructions on how to remove the rubber runflats (don't apply). Any advice?

Confused

1 Remove the bolts holding the rim half's together.

2 Pull tire off of rim.

3 Pull PVC run flat from tire.

Add soapy water if needed.

Wrap a ratchet strap around it and lightly compress it and pull it out.

If you rotate it in the tire (put soap on the pvc insert) then walk around the tire. The weight of yourself on the sidewall of the tires will allow it to "plop" right out. I have had customers strap the tire to a tree and drive them out with a jerkstrap I have used a 4 post lift to hold a tire down and used overhead puller to yank the out. We have used 2 forklifts, one to hold it and one to pull it. But just walking them out after soaping them up is the best. I rotate the pvc in the tire so it has it bloated and shazam. With some weight on the sidewall they all but fall out.

Okay I had an idea of how to stretch the beads far enough apart to maybe be able to rotate the pvc insert sideways but it still didn't work. I couldn't get the tire spread apart enough to even try to turn it sideways. Here is a pic of what I was trying to do. I could move the insert around inside the tire but not turn it sideways. The sidewalls are so stiff on the radial hummer tires! Can I use a ratchet strap to ovalize the insert like a rubber runflat to remove it or will it crack?

UPDATE. Okay I bought one of the HF knockoff "Rotozip" drill/saws and cut a single "S" type cut in each of the inserts. Not pretty considering how little room there was to move in there but they are out and can still maintain their shape. That is a dangerous job using one of those tools inside a tire! Here is a pic of the removed inserts:
