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.

Fuel qualityYour engine is designed to provide optimum performance and fuel economy using unleaded premium fuel with
an octane rating of 98 RON (93 CLC or AKI).
Porsche therefore recommends the use of these fuels in your vehicle.
Porsche also recognizes that these fuels may not always be available. Be assured that your vehicle will operate
properly on unleaded premium fuels with octane numbers of at least 95 RON (90 CLC or AKI), since the engine’s
“Electronic Octane™ knock control” will adapt the ignition timing, if necessary.
