I just got a pinch flat from going over what seemed to me to be a pretty small pothole. (Actually it was one of those ruts they dig in the road when they're doing road repair crap, but whatever.) Was about 30 degrees out, and I had *just* pumped up my tires to their recommended 120 psi about 10 minutes before I left. 700x23c, if that makes a difference, running Gatorskins. I've certainly hit potholes harder in the past, and I never got a pinch flat before.
Now, my bike lives in my apartment, so presumably when I went out in the cold, it caused the air pressure in the tires to drop. Not sure if this was the cause, but... anyone compensate by inflating their tires extra in the cold? Or is that a bad idea? Are pinch flats an inevitable part of riding (relatively) high-pressure tires in the cold, or is this all a crazy coincidence?
