Is it really the same tire because that extra savings would be great.

I heard NO might be engineered different for Porsche.

I believe the N designation means that it's a Porsche OE tire. For example Michelin PS4S has the N designation for the 20" tire but not for 19" for a 981S. Other than size I'm certain that the two tires are identical.

N rated tires are said to be engineered to Porsche specs, with what most would consider, minimal changes in the rubber formula. Most major luxury/performance brands do the same. Mercedes for example are M rated. Are they different enough to make me care??? Nope. In fact because the only Super Sports available when I needed new rears were those M rated. That what I bought. They look the same, ride the same and wear the same, so unless you're driving at the cars limit, you will never know the difference. And then I'm not sure you would even then.

Oh, and by the way, N0s will shortly become N1s and N2s just to screw with our heads. Then you won't be able to match the N0s if you are so inclined any way.

I stopped worrying about it after all the research I did on the matter about 8 years ago before I bought non Ns. Never looked back and couldn't be happier.

Do you really believe that the N rated Michelin PS4S 20" tire is engineered differently than the 19" tire which doesn't have the N designation? Other than size I'd bet the two tires are identical.

I sure don't believe it. Especially with the limited amount of Porsche's manufactured, it makes it even harder to believe a major tire manufacturer like Michelin could be bothered with it. They obviously have separate molds or tire marking mold inserts to mark the N or what ever else they are marking, but beyond that, I don't really believe they are different. It's more of the Porsche magic to get more of our money.

In my size on TR 235/35ZR20, the N0 are about $140 more for a set of 4 than the no-badge and are about $200 more than the "K1 Ferrari" variant. If those say "Ferrari" on them, I want those... detail that out in red...

I just drove over a long piece of metal and sliced up (at least) 2 tires, so I guess I need to make a decision on this pronto.

I have compared Sport Cup 2 N0 vs a Mercedes and Ferrari spec'ed/rated tire of the same size from specs on Tire Rack. The biggest difference is the tread width, with the Porsche spec having the smallest tread width. This means more radius from sidewalls to tread, or more rounded. From what I understand Porsche PSM is callibrated to expected edge rounding, but I have gone ouside N spec tries, especially for track use, and never had an issue. In fact, My Cayman ran Mercedes spec 245/35-19 SC2 front tires last year with no issues. I believe the 295/30-19 rears were not spec'ed at all (which are out of production and there is only limited availability at the moment).

As I stated on another thread; I've had 5 Porsches over 24 yrs. and the only N rated tires are the original delivery rubber. N's probably a little better and more matched to the specific car but to me money talks and I don't the translation from German to my ears.

The "N" ratings demonstrate that Porsche has worked with the tire manufacturer to optimize the tire as part of the total "system" of the car. This is not to infer that mounting non-N rated tires will cause your car to randomly fly off of the road but more that you have now become an independent tire tester. Everything being on a continuum, a N vs. non-N Michelin is something quite different than a N vs. a Chinese no-name. Somewhat amused by the decision to "save money" on the only part of the vehicle in actual contact with the earth.

What you state could be true, but it's not logical. Michelin PS4S has the N designation in the 20" tire, but not 19" for the 981S. I find it hard to believe that Michelin would change their manufacturing process for just one size, especially when the sale of those sizes represent about .0001% of their total sales.

You appear to be stating that both Porsche and Michelin are lying concerning their tire development process.

I posed this question to the rep at TireRack when I ordered my last set of PS4Ss. He said the only difference was Porsche's seal of approval and the resultant price increase. He said there was no difference otherwise.
So what did you end up buying?

Because I plan on buying from TireRack too.

And if they were lying, would you really be surprised? Companies like these lie all the time about all kinds of things. Really....they do. Surely this shouldn't surprise anyone. Take any OEM part labeled Porsche and then go to the very same manufacturer and find the exact same product without the Porsche name. Surprise!!! The ONLY difference is the name on it.:crazy:

This is true. Good example is the CTEK battery tender.

I use Tire Rack as my go to source for tires. On their website is a comprehensive description of the Porsche N designation. Here's an excerpt from the website: "Using tires that are not N-specific is not recommended..." Nothing ambivalent about that statement, but do a tire search by model and see what Tire Rack lists for a 2013 981BS with 19" wheels. One of the tires listed is Michelin PS4S which according to their website is not recommended, since it doesn't have the N rating. So why does Tire Rack list a tire for a 2013 981 BS which by their own definition is not recommended?

Why do I think that quote is from Porsche and not Tire_Rack? If Tire_Rack actually believed that, they wouldn't be recommending/selling all the other brands they do. That's a Porsche statement if I ever saw one.

Porsche isn't the only company that does this. About 20 years ago I bought my son a used Chevy Prizm. The car's alternator had to replaced about a year later, so I went to a local parts store to pick up the part. I thought that a mistake was made because the box had Toyota marked on it. The guy at the store assured me that there was no mistake, but the Chevy part was priced 20% higher and since the parts were identical, he thought me I'd prefer the Toyota part. Of course Porsche applies the same practice on steroids.

I bought the less expensive, non-Porsche PS4Ss! They handle amazingly well. They are better than the OEMs that came on my car new.
