I've had rubino pros in various states of decay on my road bike for about 3 years, no punctures. I had to do a little switch round of tyres and conti 4 seasons ended up on my road bike, went for a ride. got a flat tyre.
It might have been the glass that seemed to be everywhere i went, but it might have just been Hippy's curse.
The 4seasons were either free or cost price (I would never "buy" their clinchers)
Think about how the rubber might help cause punctures, consider that the case may not get pierced until the foreign object has gone round a couple of times, contis seem to pick up a shard and hold it there, maybe other tyres shed the sharp stuff earlier and therefore avoid as many failures.
