Would the 18” wheels have been standard on a 09 xc60? Or have they been swapped during it’s lifetime? Whether that would make any difference I don’t know, plenty of people run 18” wheels for a number of reasons. I run three tyre sets, 235 65 17, every 6 months back go to front, front go to garage, and garage go to back, and so the rotation goes on, when a new set is purchased they always go on the back, I’ve never had a problem with vibration of any kind during the rotations, ( maybe I’m just lucky).
