Michelin Pilot Alpin PA4 question

Just received my Michelin Pilot Alpin PA4 winter tire set.

As I see, the tires are asymmetrical but not rotation oriented? Is that right?
So there is only one profile type that looks like that.



Can anyone confirm?

Pretty sure that they are asymmetrical, and directional - note that the right shoulder is different than the left (asymmetrical), and the grooves across the left side of the tread all slant one way (directional). You should have two lefts and two rights (can rotate front to rear, but not side to side.)

Note that on this pic: http://www.tirerack.com/tires/BigPic...wall=Blackwall , there is the word "Outside" just before Pilot.

Thanks floydarogers . Yes, it is an asymmetrical tire and I saw the mark "outside" on it too. But there is no "rotation" arrow as I saw on many other asymmetric tires I've had.
It seems the profile is always the same, which looks strange. If you look at the car from behind, the tire profile curves on the right wheel will go upwards, but on the left wheel they will go down.

They won't go down, because then the side that is marked "outside" would be on the inside, which would happen only due to incorrectly mounting them.

In the meantime I've found some Videos confirming, that I got the right set of tires. They are not rotation oriented. Just "outside" marked.
