Wheels from Mini Cooper S on MG ZR: compatible?

Yes, with hub centric rings

Same 4x100 PCD, but the centre bore of the wheels from Mini Cooper S (66.5 mm) is larger than the hub of MG ZR (56.1 mm): you need 4 hub centric rings 66.5 → 56.1.

Rings 66.5 → 56.1

Wheel by wheel: offset and tyres

Each original wheel from Mini Cooper S is compared with the one from MG ZR 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.

  • ≈6Jx16 ET50 · 195/55R16 — Fits like the original

    Compared with the original ≈6.5Jx16 ET45 on MG ZR: shock absorber side −1.4 mm, wheel arch side −11.4 mm, tyre diameter +1.6 %. Comparison for guidance only (estimated width). Check in detail

  • ≈6Jx16 ET46 · 195/55R16 — Fits like the original

    Compared with the original ≈6.5Jx16 ET45 on MG ZR: shock absorber side −5.4 mm, wheel arch side −7.4 mm, tyre diameter +1.6 %. 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 MG ZR (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.
