Anyone tried making flat free tires with canned spray foam?

Which canned spray foams are the most dense?

There are various YouTube videos about making flat free tires for dollies and yard equipment. Small holes are drilled in an old pneumatic tire and spray foam from a can is squirted inside. Most of the videos show using one of the "Great Stuff" brand foams. One video uses the Hilti brand window and door sealer That video says the foam is so dense that it will hold screws driven into it.

I have four 10 inch pneumatic tires that were taken off a little garden wagon. Attempting to convert them to flat-free tires with spray foam would be an interesting experiment - although I have no particular plan for using the tires afterwards.
