Re: Different idea on tire repair
Yeah, insulating foam expands to fill an area, and is designed to stay put, and for it's surrounds to also largely stay put.
In a tire, as it rolls, the ground in general, and anything uneven, like rocks, or even worse, impacts from dropping off say a curb or hitting against something to dump the wheelbarrow, pushes in the foam, and makes it crumble into small pieces that are separate from the rest of the foam. And this goes on until all the foam is turned into small bits/powder, and doesn't support the tire at all.
