The logic I have heard is that one direction is better for stability on a steering axle and the other is better for traction. I'm not sure if this is based on fact or people trying to justify a "that's how I always do it". If there's any truth to it, I'd guess that trailers should have the stability setting.

I think this is one of those discussions that the right answer depends on where you were born, whether you are right handed, red headed and other imponderables.
