I am at a loss to understand how a nail punctures a tire. It seems improbable that a nail will be standing on end unless by statistical chance (having been perturbed by a previously passing automobile). If lying flat on the surface, what are the mechanics that cause the nail to move to a position of pointed-end up? I recently enjoyed two nails in the same tire, and I am sure it was not vandalism (one was positioned under the "footprint" of the tire). The statistical likelihood of two nails balanced with pointed end up is small, thus, there must be a mechanical movement when the tire first touches the nail that results in the puncture. What is it?
