I had a freak-out moment today when i heard something clicking in my tire. Pulled over and sure enough, there was a nail in there. Pretty big one too. I thought if I went at high speed the thing could fly out and I would be going nowhere fast. I was able to get into one of the local tire repair places and they put a plug in the tire. If it had been in the sidewall I would have had to get a new tire but because it was in the tread section, good to go!
