Wheel by wheel: offset and tyres

Each original wheel from Porsche Cayman 981 is compared with the one from Porsche Cayenne 958 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.

  • 8Jx18 ET57 · 235/45R18 — Check on the car

    Compared with the original 8Jx18 ET53 on Porsche Cayenne 958: shock absorber side +4 mm, wheel arch side −4 mm, tyre diameter −9.4 % : fit it with the original tyre size of Porsche Cayenne 958 (255/55R18), not that of Porsche Cayman 981. Check in detail

  • 9Jx18 ET47 · 265/45R18 — Risk of rubbing

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 Cayenne 958 (M14x1.5), 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.
