Well, yes it would make sense to me too, especially in the wet.  However,
there
seems to be a problem.  If your diagram shows the pattern of the tread as
the
tires touch the road (i.e. what you would see as tracks if you drove over
sand)
then the outer edges of the grooves hit the road before the inside/center
edges,
which would tend to push water to the center of the tire instead of
displacing
it AWAY from the center.  Hydroplaning could result.

In Kwattro's case, only one side of the car would be subject to
hydroplaning,
thus spins could result!

Just a thought ...
