There have been a number of threads on the forum regarding whether you can
                  run 225s on the 850. The answer has been no - they rub.

                  I found a combination that runs without rubbing, even at the maximum turning
                  angle:

                  Vehicle:
                  1995 Volvo 850 Turbo Sedan
                  Stock wheels: 16" Volvo alloy
                  Stock tires: 205/50/16
                  Modifications:
                  Eibach Sport Springs (lowers car 1 - 1.2 inches)
                  Koni Sport Shocks
                  ipd Anti-sway bars

                  Replacement wheels: SSR GT1 17X7.5
                  Tires tested: Kumho 225/45/17 Victoracer 700, shaved to 4/32 (competition
                  tires)
                  Specs:
                  225/45ZR17
                  Rim Width 7.5"
                  Section Width 9.2"
                  Tread Width 8.6"
                  Diameter 24.6"
                  Revolutions per mile 848

                  The offset on the SSR wheels in the 7.5" width seems to be enough to place the
                  tire correctly in the wheel well, even with the Eibach springs. The combination
                  REALLY fills the wheel well visually.

                  I checked Kumho's ECSTA Supra 712 (Street Tire) and the diameter is a tad
                  larger - 24.9 inches. That might be a bit tight with the lowering springs. Note,
                  however, that the lowering springs also may be keeping the car off the tires
                  given their higher spring rate. If you can locate a tire with the same or smaller
                  diameter I don't see why you'd have a problem.
