Really common up here. Really corrosive environment, due to the chemical they put on our roads in winter.
People forget about their spare, till they need it.
My shop torches off about a dozen spares a year.
Basically, torch off 1 side of the retainer bar (that holds the tire up) at the end of the winch cable.
I wonder what % of pickup spares are carrying under 20lb of air. My spare is 13 years old and probably has less than 50 miles on it. I have a good 4 year old tire on the pickup that will replace it when I buy tires later this year. They get weak from age even out of the sun.
