Was over on youtube watching some video's on D2's and remembering my youth and noticed this one. Interesting idea for tire repair, but wonder how long it'll hold up carrying weight? Maybe in a wheel barrow?

Considering that a wheel barrow carries about double the weight on the front tires of a typical LT, not long.

He installed 24 oz of insulating foam which is a space filler, not load bearing. The foam that is actually used for that purpose would weigh over 16 times as much because it is load bearing.

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.
