Still not sure Im personally comfortable running repaired tires on my, my wifes or my sons bikes as they get used at speed... used for hours at a time and changing a tire for a fresh one is not an emotional event for us.. just a few minutes in house or at the shop at no cost. And tires don't last very long for us anyway...
BUT, it does seem to be a non issue in real world use
Can I have all of your tires with nails in them?
The bottom line is to each their own, and just because I do it or someone else does it, doesn't mean than anyone else has to do it. For the record, I have also plugged my Wife's rear tire and she rode that till it was at end of life. And no, that doesn't show how little I care about her, that shows how confident I am in plugging a motorcycle tire. I have left out of my garage for a 5k mile solo trip on a plugged tire and didn't think twice about it. I would do the very same thing today.
