850 Wheel Fitment.

sorry if its been covered, link me if it has.

im new to modifying volvos had a 850 for my first car loved it until i wrote it off. then i got into nissan s13s and learnt alot with machanicals and drifting, and wheels offset and such, so my question is what sort of wheel width and offsets can a volvo 850 take? looking at 17x8.5 +20mm offset for the front and 17x10 with +15 for the rear.  any pics or info would be appricated
