Yes, with hub centric rings
Same 5x110 PCD, but the centre bore of the wheels from Jeep Commander (71.6 mm) is larger than the hub of Saturn Sky (65.1 mm): you need 4 hub centric rings 71.6 → 65.1.
Rings 71.6 → 65.1

Wheel by wheel: offset and tyres
Each original wheel from Jeep Commander is compared with the one from Saturn Sky of the same diameter: how much closer the wheel gets to the shock absorber or how far it sticks out of the wheel arch, and whether the tyre keeps the same overall diameter.

Before fitting the wheels
An identical hub is not enough: offset, width and diameter change the position of the wheel, and larger calipers can touch a smaller wheel. Original wheels often use bolts or nuts with a specific seat: keep the fixings intended for the wheel, with the thread of Saturn Sky (Ecrous - 12x1.50), tightened to the torque shown on its vehicle page. Finally, check that the size is among the approved fitments for your vehicle. This comparison is for guidance only: have the fitting approved by a professional.
