Spray foam for flat proof tire...Will it work? Let's try!!

What happens here

This video documents an experimental DIY attempt to fix a flat wheelbarrow tire by filling it with expanding spray foam. The process involves removing the tire's valve stem core, injecting a large quantity of spray foam into the tire, and attempting to distribute it evenly by spinning the tire. After an hour of curing time, the tire is tested under load to assess if the foam successfully created a solid, functional tire. The conclusion demonstrates that this method is ineffective and messy.
