I have been trying to decide what to do for a spare tire. (not mine, the tear drop) So many choices. Since my tires are new and will likely not get too many miles on them, I was thinking of a tire plugging kit and my 12 volt compressor would do, since they are always in the car anyway. Seems the last 15 years or so, if I get a punctured tire, I usually fix it on the car or truck with the plugger, if it was possible. Haven't had a blow out since the younger days running tires with the wires or cords hanging out.
