Inner tube protection.
We have an electric wheelchair that we use in the yard like a tractor.
We call it the "mule", very handy.
One of the tires went flat, the leak was on the inside next to the rim.
These have a split wheel that makes it easy to do, but there is a possibility of damage.
So we ordered a pair of replacement tubes, then the light went off.
Cut out the valve stem.
There is a line at the outside edge, so cut it open along the line.
Put just enough air in new tube to make shape.
Put the old tube over new one, valve stem through the hole where old one was.
What is not shown is we used foil tape (hvac duct tape) to go around the outside to hold it in shape until we get it inside the tire, it gives maybe some protection from stickers.
Inside the tire, the wheel halves go back together and all good.
