Roofing nail? Whenever I get a flat, the shop usually finds the culprit

Drywall screws are the usual suspect here. They just seem to be
attracted to tires. I was never sure how they got flipped up and
driven in but when you pull them out they are always perpendicular to
the tread. The fix is usually just shooting in a plug. I know they
have a bad reputation but I have never seen one fail and construction
people get lots of flats. With all the nail guns, there is always
"air" on the job and someone has a tire plug handle in their tool box.

I've been plugging my own tires (yes, steel belt radials) since I can
remember. I've NEVER had one fail. And that myth about not using them
in sidewalls? I had a puncture in the sidewall of my Jeep tire,
plugged it, ran it for 25,000 miles. It never failed, the tire tread
wore out.
