Wheels from Mini Cooper on Audi S4: compatible?

Yes, the hub is identical

Same 5x112 PCD and same 66.5 mm centre bore: wheels from Mini Cooper bolt on and centre on Audi S4 without rings. You still need to check the offset and tyres, detailed below.

Wheel by wheel: offset and tyres

Each original wheel from Mini Cooper is compared with the one from Audi S4 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.

  • ≈5.5Jx15 ET45 · 175/65R15 — Fits like the original

    Compared with the original ≈6Jx15 ET40 on Audi S4: shock absorber side −1.3 mm, wheel arch side −11.4 mm, tyre diameter −4.1 % : fit it with the original tyre size of Audi S4 (195/65R15), not that of Mini Cooper. Comparison for guidance only (estimated width). Check in detail

  • ≈5.5Jx15 ET50 · 175/65R15 — Check on the car

    Compared with the original ≈6Jx15 ET40 on Audi S4: shock absorber side +3.7 mm, wheel arch side −16.4 mm, tyre diameter −4.1 % : fit it with the original tyre size of Audi S4 (195/65R15), not that of Mini Cooper. Comparison for guidance only (estimated width). Check in detail

  • ≈5.5Jx15 ET46 · 175/65R15 — Fits like the original

    Compared with the original ≈6Jx15 ET40 on Audi S4: shock absorber side 0 mm, wheel arch side −12.4 mm, tyre diameter −4.1 % : fit it with the original tyre size of Audi S4 (195/65R15), not that of Mini Cooper. 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 Audi S4 (M14x1.50), 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.
