And why do you really think that? What stake does Porsche have in this other than working closely with tire manufacturers to produce tires that work better with their cars than off-the-shelf models? Porsche makes no money frm the tires they spec for the cars... As Jim mentions, it's not just a marketing thing - several models of n-spec tires have used different compounds and even very different tred patterns than their non-N-spec counterparts of the same model from the same manufacturer.

From what I've read, the Good Year F1 Asymmetric tire was rated higher because of a slightly higher wet-surface grip. In most of not all the other categories the PS2s were still rated as good or better.
