Got a flat yesterday in the rear tire of a Panaracer Pasela Mesenger PTs. Turned out the tire had a little nick in it, on the centerline of the tread and some debris had wedged itself in there and gave me a flat. (So much crap on the shoulders right now after the blizzard a few weeks back)

Tires are otherwise in good shape. Do I replace the tire or rotate it to the front and hope it doesn't happen again or is that stupid.
