Tire and rim sizes
Extensive tests are performed before specific tires and wheels are approved by Porsche. Your Porsche dealer has informa-
tion 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 driveability, stability while in motion 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 combi-
nations.
* 911 Carrera 4S, 911 Targa 4S: Summer tires 19-inch only
** Only approved together with 17 mm spacers
