hey all, just got my winter tires on, they installed them with the tread pattern going one way on the right side and going the other way on the left side... Does it matter for these tires? according to another site they are not uni-directional, see pic below.

Thx for your input.

 

If the tire is directional, it will be printed on the sidewall. You'll see an arrow followed by "rotation" to indicate the direction the tire should roll.
