Tire and rim sizes
Extensive tests are performed before specific tires and wheels are approved by Porsche. Your Porsche dealer has information
about approved tires and wheels and is happy to assist you. If aftermarket tires and/or wheels are installed which are not
approved by Porsche, the vehicle’s roadability and handling characteristics might be impaired. Since Porsche has no data on
such combinations, Porsche cannot stand behind the safety or durability of these aftermarket combinations.
* Snow chains Can be mounted only on the rear wheels; maximum speed 30 mph/50 km/h.
Use only Porsche authorized fine-link cross-type or edge chains.
Snow chain clearance can be guaranteed only with the tire + rim combination marked .
