>>1720264I was doing a track stand at a stop light a few days ago, heard crunching noises. Looked back and realized I was in the process of pulverizing a sizeable fragment of glass with my rear tire. Doesn't seem like it got punctured, though, probably because of my fat mtb tires.
In fact, I can't remember ever getting a puncture on the road, street or sidewalk because I've always had an mtb.
