If we follow that analogy, then race cars ought to use extremely narrow tires in the wet - but they don't. Obviously the grooves provide a place for the water to go - and that is important for wet traction.

What evidence we have is reports of wet traction issues at elevated inflation pressures. Clearly these are anecdotal, but it is also clear there must be something there.
Does wet traction fall off linearly from placard pressure? Is the wet traction curve fairly flat near placard pressure, then fall off suddenly at some elevated pressure? We don't know.
Caution should be observed!
