The 20" Continental 4x4 Sport Contact N0 is a Porsche approved OEM tire. It should have the "N0" designation somewhere on the sidewall. If not, check back with your dealer and find out why. You should only use the Porsche approved version of a tire.

Other Porsche approved tires for your car include the Michelin 4x4 Diamaris N0 and N1 and the Pirelli P-Zero Rosso N0. Of these four tires, I have seen the most favorable comments for the Michelin 4x4 Diamaris N1. I do not have personal experience with any of them.



Don't want to start a flame war here but why should one only use a "Porsche" approved tire?
