Tire and rim sizesExtensive 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 combinations.
