Yes, the hub is identical

Same 5x115 PCD and same 70.3 mm centre bore: wheels from GMC Terrain bolt on and centre on Opel Cascada without rings. You still need to check the offset and tyres, detailed below.

Wheel by wheel: offset and tyres

Each original wheel from GMC Terrain is compared with the one from Opel Cascada 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.

  • ≈7Jx17 ET43 · 225/65R17 — Fits like the original

    Compared with the original ≈7.5Jx17 ET41 on Opel Cascada: shock absorber side −4.4 mm, wheel arch side −8.4 mm, tyre diameter +4.9 % : fit it with the original tyre size of Opel Cascada (235/55R17), not that of GMC Terrain. Comparison for guidance only (estimated width). Check in detail

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 Opel Cascada (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.
