Gosh, all this discussion has now got me worried. I've just realised that I'm still using the same pair of tyres that I fitted when I bought my current audax bike five years ago. I can't even remember what they are, apart from 28x700. Over that time, and about 12,000km, I've had precisely five p--c----s, all in the back wheel (and three of them on the same event, the 2006 Etape Du Tour). I hadn't planned to change the tyres but no I'm worried that I'm being too complacent. And if I change them, what should I fit instead?
Oh decisions, decisions!
