I wonder if that also goes for its competitors.
I also wonder if when they say “used,” they mean “used” as in “injected from the can into the tire” or “used” as in driving on wheels that have it in the tire. If they simply don’t recommending dispensing the product in freezing temperatures, that doesn’t mean it can’t be dispensed at warm temperatures and driven on later.
Nonetheless, @Barkydog, the odds of this working, even for a little while, seem to be dwindling. Just buy inner tubes and have a friend help you install them. You might consider buying a cheap set of motorcycle tire tools if the bicycle tools I recommended earlier are insufficient.
