Remove valve stem core.Get a tight fitting piece of clear tubing that will slide over the valve stem.Drill 3/16" hole other side of stem in the tread.Get a can of great stuff foam.fill till the foam comes out of the 3/!6" hole.Valve stem will be on the bottom.make sure the tubing will not slide off can or valve stem or you will have a mess!Use hose clamps if needed.I did this to my pressure washer tires & I can stand on the tires,no more flats.
I'm going to try that on my wagon tires.
