Wheels from Porsche Cayenne on Porsche Cayman: compatible?

Yes, the hub is identical

Same 5x130 PCD and same 71.6 mm centre bore: wheels from Porsche Cayenne bolt on and centre on Porsche Cayman without rings. You still need to check the offset and tyres, detailed below.

Wheel by wheel: offset and tyres

Each original wheel from Porsche Cayenne is compared with the one from Porsche Cayman 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.

  • ≈7.5Jx17 ET55 · 235/65R17 — Check on the car

    Compared with the original ≈6.5Jx17 ET52 on Porsche Cayman: shock absorber side +15.7 mm, wheel arch side +9.7 mm, tyre diameter +12.2 % : fit it with the original tyre size of Porsche Cayman (205/55R17), not that of Porsche Cayenne.

  • ≈8Jx18 ET53 · 255/55R18 — Check on the car

    Compared with the original ≈7.5Jx18 ET57 on Porsche Cayman: shock absorber side +2.3 mm, wheel arch side +10.4 mm, tyre diameter +10.3 % : fit it with the original tyre size of Porsche Cayman (235/45R18), not that of Porsche Cayenne.

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 Porsche Cayman (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.
