familyman;86529 wroteYes, rare. I was planning to buy Galaxies new from a USA Volvo dealer. Nice wheels, look easier to clean (knees & toothbrush for coronas). But few tyre choices today, means even less tomorrow.
205/55/16 is a very common tyre size, and for a post 86' 240, the correct size. They are used on every astra sized car..... 50 profile uses similar.
And no you want to go lower offset, so 20 for a wider rim. Particularly for the rear.
