Has anyone heard of Michelin " N ZEROS "?

STLPCA

I haven't, and apparently <a href="http://www.michelin.com/us/eng/tire/catalog/p1.htm" target="_blank">Michelin </a> hasn't either. Perhaps you are referring to Porsche's "N number" approval of a Michelin tire as "N0" (or N zero) as distinguished from N1, N2, etc. My Michelin MXX3 tires are designated "N0."

Yes. It is called Michelin Pilot Sport with a Porsche "N" specification. Look here for more info on this "N" thing:

It's important to note that the N rating is from Porsche, not Michelin. Other manufacturers have N ratings as well (Pirelli, etc).
