I checked with Michelin direct and they had no "N" types for the size rim on the 968, front or rear.

as much as porsche would like you to think there is something magical about N tires, there isn't.  it only means that those tires meet the specifications that porsche set down.  it does not mean that another tire does not also meet those specs.  it likely only means that that the tire manufacturer did not submit it to porsche for review and approval.  it is a very expensive and time consuming process, and most manufacturers don't feel that it is worthwhile.

Thanks, I agree. I finally found some Bridgestone Potenzas  $112.45 front and $150.45 rear N3 rated, and some Pirelli P Zeros $122.45 front and $181.70 rear also N3 rated at the Tire Rack. The Pirellis might have availability problems as only one rear in stock.  $17.77 per tire delivery to So. Cal.  Having found them I thought I'd pass it along for comparison.

I noted a comment ( on a different thread , but posting this question there would have been a bit OT ) that tires may react and perform differently on different cars - while I get that because of any given car's characteristics compared to another's, I am curious if a top rated tire in a majority of categories can be be outperformed by a lesser rated tire in those same categories in a different car. So just for the sake of argument , let's say the Pilot Sport is deemed to be the best all-around tire for the 968 and the P Zero falls somewhere in third or fourth place on the 968. Could that P Zero however be a superior performing tire compared to Pilot Sport, on a BMW M 3 ? Or on any other car for that matter ..within reasonably close vehicle parameters of course, I'm not talking about comparing tires on a Lotus Elise vs. a Dodge Ram, lol.

I would have to say undoubtedly the answer is yes. I ran Michelins on the Volvo and the Pirellis are vastly superior, so, same car, two very high quality manufacturers, and remarkable handling differences.

 

So, it was n't like I went from JC Penney off market brand to Pirelli.

absolutely.  the reasons are complicated, but among them are how the tire reacts to heat, friction, load, and weight shift.  each car handles and transfers loads differently.  the best you can do when choosing a tire is to find tests on a car set up similarly in design, and most importantly, similarly in suspension and geometry.  for example, don't expect a rear engine rear drive car to react like a front engine front drive.  also, strut cars react differently than double wishbones.

With a little fender hammer mod for clearance. Remimber, wider tire on the back.

do you guys (in the US) have access to Bridgestone Potenza Adrenalin S003's? (I'm in Australia)

I have these on my Carrera 3.2, brilliant tyre. Will be looking at replacing some old and quite hard Sumitomo's that are on my newely acquired 968 Coupe
