Fit snow chains only to the rear wheels, and only with the tire/rim combination listed in the Technical Data.
To ensure adequate clearance between chain and body, Porsche recommends only the use of fine-link chains such as those approved by Porsche.
Follow instructions issued by the supplier of the chains.
Different states and countries have varying statutory requirements regarding maximum speed. Check with local authorities for possible restrictions.
Remove chains as soon as the roads are free of ice and snow.

Due to new speed and load ratings for radial tires, new designations have come into force for snow tires for your Porsche.
The designation to be used for ZR tires is e.g., 265/40 ZR 18 (Z = code letter for radial tires for speeds above 150 mph / 240 km/h).
