The wheels are from an XC90 and need hub centric rings to fit the XC70 hub, otherwise the 17" wheel itself fits fine. Issues is fitting the 235/65R17 tire which is 29 x 9.3. More information in the link below, but the only real issue with fit is the lower front section of the rear wheel well needs to be 'massaged' a bit [emoji6].
I've since added 25mm spacers to the rear wheel which required further modification to the plastic wheel well liner. Without the spacers and only performing the work to the front section the tire would tuck into the wheel well without rubbing for the full length of the suspension travel, but with the addition of 25mm per side the tire would rub the inner lip of the liner when loaded of on drop offs. I simply removed the liner and trimmed the outer edge of it so that its sits tighter against the outer edge of the wheel well. This provided enough clearance for the tire and the spacers help a lot with the overall look and feel of the vehicle.
