I finally got these tires to puncture. I found a street that had 3 patches of broken automobile glass (they looked fresh so they were probably night-time break-ins). I rolled my Swift through the succession of broken glass, then checked the tires. The front tire had sprung a tiny leak. It was a miniscule puncture, detectable only by the hissing sound from the leaking air. The back tire was fine. Strange....I usually never get front wheel punctures.

The good news is in how easy it was to unmount the tire and patch the tube. I easily peeled away just enough tire bead with the tire lever to expose the area of punctured tube, slapped on a Slime patch (these are really excellent patches, by the way), then re-mounted the tire bead by hand. Quick and effortless. My Primo Comets required a tire lever and a whole lot more effort.

Still not bad for a non-kevlar belted tire, considering most normal every day rides don't include a deliberate rolling through 3 blanketed patches of freshly broken automobile window in succession (they were pretty sizeable hunks of glass, too).
