I no longer have a spare tire.
I should though.
But the pickups spare tire is hanging under the flat bed, So I would have to lay on the ground under the car to fget that one.
And the working car is a compromise of interior for tools and material. No room for a tire.
IN both cars I have those flasks with quick fix in them. And yeah, they would not work on a big damage.
I am thinking that in some situations I could use it to at least reinflate the tire and get home.
