A uni-directional tire would be marked on the sidewall with a rotation direction arrow. Look at this pic of a directional Goodyear Eagle:

See how it shows the word "rotation" and an arrow on it?
The PS2's aren't so marked. They say "outside" on the sidewall, which means they can be on either side of the car as long as the "outside" is out... hence they can turn either direction. A directional tire is designed to only rotate one direction.

I suppose it's conceivable you got regular Pilot Sport's?!? The 'plain' Pilot Sport is indeed a directional tire, vs. the Pilot Sport PS2 that's available over here as OEM tire.
Is the tread pattern on your tires a 'V' shape or an 'S' shape?
