Mostly directional tires are better at clearing water. If your
existing tires wear evenly, you can consider them. But if
cross-rotation is a necessity on your car, directional tires are not
for you.

They are still not common enough for NTB (insert your own vendor) to
rotate them properly, front to back only. IF they are put on backward,
they will make a lot of noise and wear very quickly.

I've had both kinds and really don't have a preference. The benefits
are subtle if any. Some tires look directional and aren't!

 Plus you MUST use pull through parking only. Never use reverse.

 I find them vastly superior in the rain. I agree, most places try to put
them on wrong and you need to carefully watch installation and rotation.

 The Yokohama DbS2's I have now are directional, and they are merely
good in the rain. The Bridgestone RE950's I had before were not
directional, and were incredible in the rain, providing utter
confidence even with fairly worn tread. The Bridgestone's are superior
in every way except ride quality (they are harsh) and price.

In balancing the overall performance of the Yokos, their designers may
have achieved some rain performance by going to a directional design.
But that's not the same thing as excelling in rain in absolute terms.
It may mean that they gained a few points in other areas without
sacrificing too much rain performance.

And, a lot of this is marketing.

 I have RE950 on both of my cars and they are directional, and they are much
better than the non-directional RE92 or Goodyear Eagle RS-A I had before.

And to the original poster, I'm pretty sure directional pattern is there to
better expel water from underneath the tire to avoid hydroplaning.

I'm curious. How critical is cross rotation? I would think that it's
just an old school way of doing things because directional tires are a
relatively new tire design.

 Woops!! I stand corrected, and agree that the RE950 is directional. I
was thinking of its precursor, the RE930's that were on the car prior
to my 950's:

"Features: - H-Speed rated, high performance tire designed to match the
demands of sport cars and sedans. - Non-directional Variable Radius
Groove (VRG) tread pattern delivers efficient high volume water
channeling to resist hydroplaning."

I thought cross-rotation went out with bias-ply. When radials came
out, we were told not to switch sides (and therefore rotation
direction), that we were to keep radials mounted on the same side
throughout their life, rotating only from front to back.
