I rock a plugged front tire on my Interceptor, and have for every single time I've been on the bike, since I bought it with a flat tire that was bractically new, as in it still had to be scrubbed in. It is not the Autozone, or Napa or Carquest type, they are all crap IMHO. It's a Tech tire plug. The structure is the one concern I have with it, which I doubt will ever be a problem. The cool thing about the Tech tire repairs is that they don't just glue in, the "glue" they use in conjunction with the coating on their tire repairs causes a chemcal vulcanizing to occur. It's a much stronger bond than just glue. I'm not sure about the story on how the hole got in the tire, I'm guessing it got it on it's last ride before I got it, or maybe while it was sitting in the guy's shed someone messed with it. I'm not afraid of it being plugged. One last note, a plugged car tire loses it's speed rating, according to tire manufacturers.
