Several years ago while driving our full size van from NC to Las Vegas, I found a 3/8" x 2 inch bolt sticking in the center of my rear tire. As I was in the middle of nowhere in the Nevada desert when I discovered this, luckily there was a small old tire shop licated behind the filling station where I discovered the bolt. The man there used the ole stickey rope plug and plugged my tire. I continued on to Las Vegas for my stay, then 3800 miles back home thru Utah and the rest. The tire never lost any air!!! And I mean never... as in for the next 2 years until I sold the vehicle. If it works on a bolt hole that large, a small nail is certainly less troublesome.
