Information
- Rework on wheel bolts is impermissible .
Information
- Always observe the specified tightening torque. → Tightening torques for wheel mounting
- In the case of vehicles with PCCB (Porsche Ceramic Composite Brake), screw the two assembly aids (assembly pins) into the wheel hub before mounting the wheel.
Wheels with sensors for TPM: Before changing wheels (e.g. changing from summer to winter wheels), check that the wheels are compatible with the vehicle's tire pressure monitoring (TPM) system.
- In the event of heavy soiling, clean the wheel bolts and the concavities in the wheel with a lint-free cloth.
- Always apply a thin coat of Optimoly TA (aluminium paste) on the thread of the wheel bolts, on the shank and between the bolt head bearing surface and spherical cap ring (under the head) -arrows-
. The spherical cap bearing surface -X-
of the wheel bolts that face the wheel must not be greased
.
-A- - Spherical cap ring (permanently connected to the wheel bolt)
-X- - Spherical cap bearing surface facing the wheel (do not grease)
- Always replace damaged wheel bolts.
This damage includes mechanical damage to the thread, the spherical cap and damage resulting from seizure of the bolt head bearing surface and spherical cap ring. It must be possible to rotate the spherical cap ring on the bolt shank and to move it in axial direction.
- Screw in wheel bolts by hand and then tighten evenly. Start at the top when tightening.
- Silver wheel bolts (up to model year 2011) = 130 Nm (96 ftlb.). 160 Nm (118 ftlb.) also permitted retroactively.
- Silver wheel bolts as of model year 2012 = 160 Nm (118 ftlb.).
- Black wheel bolts = 160 Nm (118 ftlb.)
