You know the truth, we don't. I know that tuners (and tire dealers) love to tell customers that there is nothing different about the N-rated tires but there is. 

The "truth" is that Porsche did not invent the MPSS, whether they made some changes in the 345 size which Futch has on his CGT and the N0 stamped ones is the moot point.

You believe they do in all cases when they give the N stamp, in this case I don't believe there is any difference. It would be great if we had some industry insiders on the forum who could tell us definitively, sometimes you do appear to almost blindly believe everything Porsche feed us without question - just saying Smiley
