Which tyres are most resistant to getting punctured?

Interesting thought.

But I have learnt my lesson going over some chevrons flittering past some non moving cars I felt a bumb -bump -bump and put it down to the chevrons because as i came off they stopped but still wasn't right, so past the traffic and on the the motorway for a short 2 mile home and it wasn't until I inspected the tyre that I saw a 4 inch nail in the tire and then out of the side  :eek and the fading bump bump was the bit left sticking out being bent over the tyre was still up but a bit soft the next day when I rode it to the fitter.

So after that I appreciate why they cost so much and I keep out of the chevrons where all the crap gets washed to it was a bridgstone
