Question

I know this may havea simple answerbut idk what it is. So I’m pretty sure there aren’t little nail trolls laying nails vertically all over the street so where are the nails coming from and how do they keep getting in my tires?

Nail doesn’t need to be pointing up. Imagine the typical joke of stepping on a rake. Let’s say as tire approaches the first thing the rubber touches is the head of the nail. As it presses down, the other end with the point will lever up. Tire rolls over the point and that’s it.
