And like I said before, what you see in Lapland isn't applicable in the real world. Whatever tire is there is only applicable to their cars running at their playground. 

Porsche does not certify any studded tires for their cars. Run at the owners' risk as they say. Especially those that aren't in factory fitment sizing. 

Porsche has a whole village of mechanics to maintain their fleet of over 100 cars there, and direct access to ECU programming for tire circumference differences.
