Anti-Puncture Tyres At-a-glance

Obviously in Schwalbe's tests, the diamond pattern somehow allows more effective water dispersal, possibly combined with more grip? I don't have their test data to examine though. But they wouldn't just have patterned/dimpled/siped and slick versions of the same tyre....for no reason?

Funnily enough, even though the diamond pattern forms a uniform looking checkerboard effect, just by looking at it, you can see lines that water would follow, if a good speed was built up. I think it would have zero effect at commuter speeds.

As for race tyres being in this thread, from the very beginning, they were in their own section of the list. I have not included any tyres with minimal (ie. none) puncture protection though. All must have at least a kevlar belt, or vectran. Fair?

Where are Schwalbe's tests?
It's not for no reason, it's to make people buy two sets of tyres for dry and wet roads.
Or, how about they found that the diamond pattern allow for a more flexible casing which increases grip? That has nothing to do with water dispersal but offer increased grip in the wet - did you think about that as an option?
In the case of the Zipp Tangente tyres you used as an example earlier, note that the centre is slick and the sides are dimpled. This looks more like dimpling for aerodynamics than any consideration for wet weather grip. Perhaps diamond patterns lower rolling resistance so they score better in those German tests I can never read?

What lines would it follow? It's a chequerboard, with even size squares, so using the 'water follows path of least resistance' idea it could go anywhere.
Commuter speed? Bits of my commute here are at >50kph. In Melbourne, >60kph.
How fast do I need to be going before I can feel it man?
