tires is used, this may impair the driving be-
havior.

distances in cases of emergency.
For safety reasons, replace the tires before
the wear indicators appear (webs in the tire
grooves, 1.6 mm high).
fNever deactivate the Porsche Stability
Management (PSM) system.
fIf the tire on the spare wheel is older than
4 years, the spare wheel should be used only

vehicle. However, it is also possible to fit snow chains on only one axle (preferably the rear axle).
For safety reasons, vehicles with snow chains must not be driven faster than 30 mph (50 km/h).
fObserve the respective road traffic regulations.
fUse only Porsche-authorized fine-link cross-type or edge chains.
