What does it mean for a tire to have a Porsche N spec approval?

A Porsche N spec approved tire is one that has passed a series of difficult and diverse tests designed by Porsche engineers to ensure maximum performance and safety under a wide range of driving conditions. To qualify for this approval and “to be an Original Equipment tire provider on a Porsche vehicle or be approved by Porsche for the replacement market requires the joint product development efforts of the tire engineers working alongside the Porsche vehicle engineers.” In some instances specific tires will only be approved for specific Porsche applications or models.
