There was a big deal made about plugging a tire that had fix a flat in it, back when it first came out. Seems that friction from the tire plug tool against the steel cords in the casing could cause a spark and explosion. Was it true or just an urban legend? Damned if I know. I do know that stuff would sure make a mess.
And I'll take a plug over a patch any day.
Fix-A-Flat type goo is frequently now standard equipment in that hole known as the spare tire well.
My Pontiac has it. Many cars now have it.
Consider: A can of goop weighs a pound, a donut weighs 20+ lbs.
A can of goop costs a buck or two, a donuts costs 50 (?) bucks.
Goop destroys the tire pressure monitor, which means somebody gets to sell you a new one!
Not to mention the percentage of the population with the skill and motivation to operate a car jack is probably nearing the percentage of the population that knows how to drive a stick.
My manual says call onstar or somebody if you get a flat. That's fine, until the warranty runs out.
