Spray foam for flat proof tire...Will it work? Let's try!!
What happens here
Using a valve stem remover tool, carefully insert it into the tire's valve stem and unscrew the small valve core. This action will release any remaining air from the tire and create an open port for injecting the spray foam. The removed valve core is shown.
Goal: Depressurize the tire and create an opening for foam injection.
