I didn't know there was such a thing as tire plugs.  I mean, I knew that there were plugs for tires, but I thought the tire had to be deflated and the plug inserted into the tire only after the tire was deflated and off of the vehicle.  I never realized there was a DIY kit to use with air in the tire for roadside emergency situations.  Seems easier than getting the spare for a nail or screw puncture.  
 
Peace.
