I used to work at a Goodyear in my late teens until about 20. We did all kinds of work, but flat repairs were very common. One thing I learned, given we had to return the spare tire to the trunk and retrieve the flat most times, was that 90% of the country appears to be driving around with up to 100 pounds of junk they really don’t need in their trunk.
