#3: Fix-A-Flat
Yes we are all too aware of the stigma surrounding canned tire inflation products; among these a face-full of dried foam at tire-change time and sticky residue on the inside of the rim. However compared to the damage one risks when attempting to drive on a torn tire carcass or worse still, on the rim itself, makes such concerns laughable in comparison.
There is little doubt that a can of tire inflator can make the difference between being stranded/ having to hike back to civilization and driving back out of trouble to worry about scrubbing the inside of your rims another day.
