Working in construction I learned to keep a plug kit in my vehicles. I used to get nails in my tires so often it wasn't even worth it to switch to a spare. I would just plug them and keep on truckin'.


(Disclaimer: A plug is technically only a temporary fix, as tires are supposed to be both plugged and patched for a proper permanent fix. However, I never had a problem with tires that were just plugged, especially since I don't usually get more than 30,000 miles out of a set of tires.)
