Porsche doesn't specify a specific N number by model but they do state that you shouldn't mix N numbers on the same car
This seems a bit confusing to me.....If the N designation was approved by Porsche, what would be wrong with putting N2's with N3's? Aren't we splitting hairs a bit on this? I have N2's in the back with N3's in the front, same brand of tire Pirelli Zeros, and I have had zero problems!
Just because they say not to do it doesn't sound good enough to me, because I'm not hearing WHY this is not advised?
Don't they also say not to use any tire without the N specification, but plenty of people on this board have had great success using non N specified tires?
Sorry for the rant...but...
Call me skeptical
