Recommended use of winter tyres
Summer tyres provide optimum performance at ambient temperatures above +7 °C. Below this point, the tyre compound begins to harden and braking distances are increased. We therefore recommend that you fit winter tyres during the colder months of the year. Only then can you enjoy the highest standards of active safety from your Porsche. All winter tyres approved by Porsche are identifiable by the ‘N’ designation on the sidewall.

Manufactures: Vredestein

The WINTRAC XTREME is the first winter tyre to be developed in partnership with Giugiaro Design. Aggressive, firm lines give the W-shaped tread its powerful appeal. Sipe technology was a priority for Vredestein in the design of the WINTRAC XTREME. Optimum Silica Processing^TM (OSP^TM) technology is incorporated in the fabrication of the tread compound, enhancing the winter performance and improving grip on wet surfaces. In addition, the equal distribution of pressure across the contact area ensures an even wear pattern, whereby low noise levels are assured throughout the tyre’s life-span.
