From what I understand, N0 is the first release of a tire that meets the Porsche specifications. Then as the tire is revised, the number goes to N1, etc... So the N3 of one tire couldn't really be compared to the N0 of another tire, the N0 of that brand/model could be a better tire. Or worse depending on your needs.
