Rotating tires without knowing their previous position on car

[Jello53]

Hi guys,

I have a set of winter tires on rims which were removed by a garage (Cdn Tire...) last spring. I've finally decided to start doing my own tire changes as I happened upon a second set of wheels last year. But low and behold, as I opened the bags my tires+rims were in, they were not marked with their original position from which they were removed.

Can I just put any tire anywhere on the car? I see no arrows on them which leads me to believe they can be interchanged between the driver and passenger sides, but I'm worried about wear. Note: they are far from new -- this is likely the last winter these tires will see, they came with my Yaris 2009.

Any tips are appreciated. Thanks!
