Thanks for the id. Panaracer sounds right. Probably Kevlar. I didn't expect the tube to bulge through anytime soon. But riding on no tread and no rubber wasn't a bright idea.

RoadRaven, you were very polite and diplomatic. Thanks again. Next time you can just tell me that I'm being an idiot (but do it in a PM please!).
