Inflatable wheels - on wheelbarrows, wagons, etc.

I never did think a lot of putting inflatable wheels on dollies, wheelbarrows and the like. In the beginning, they are marvelous. Eventually they begin losing air and soon you buy new inner tubes or even a whole wheel. If you know where to look for the right size. My neighbor had a pretty old wheelbarrow that needed repairs. She said it had to have a new wheel. At first, she wanted me to fix it up. Instead, she bought a new one. And gave the old one to me.

She had lost the axle. No problem. A length of rebar made a perfect substitute.

I made two holes in the tire itself, near the hub. One was for letting in air. Not sure how necessary that hole was. But the other hole was for a
plastic tube. I inserted the tube about a half inch and then screwed the other end of it to a can of expanding foam. A couple of bursts of foam had the tire as firm as a new one and it will never need to be re inflated. The wheelbarrow will serve me as long as I continue to need one.
