Not something I’ve had to resolve with these but I have had a couple of other similar situations.
A bushie type fix would be to make new tyres either by wrapping thick belting around a hub and fusing it or cutting the correct size out of an old earthmover tyre, half a tyre a side and heating them to force them over the hub then using retread bonder to stick the two halves together.
In my experience you need newish rubber to do it, the older ones lose their elasticity and won’t come back to the correct shape. There’s also stuff called block or blocking rubber. I’ve cut “tyres” out of that too.
