I should have been clearer... there are N0 and N1 RE050A on the market. There's a s substantial difference between the two. The N1 is superior.

Ah, I see what you mean, yes, they are the N1's. Did not know about the difference between the N0's and N1's either, glad they are the N1's then

Great! If you have a chance to compare your new RE050A N1 with someone's new PS2 would be interesting to evaluate the expansion joint crashing effect.

With the PSS you mean? will do if I can I'm also very interested in knowing the water evacuation capabilities of the PSS in highway driving compared to PS2/RE050, their thread design looks very sporty, like the Cups, but less standing water friendly.

I meant new RE050A N1 vs new PS2.

Reports say that the PSS is better in wet/dry than the PS2 and quieter too.

I am mounting RE050 N1 this week. I could of baught the PSS but as they are not N rated, I did not want them. 

 I will go to the Nordschleife at the beggining of october for 5 days and will not put the Michelin Cups on, as I am worried about the 'cold' temperature, but will have  these Bridgestone. If it is cold and humid I will probably be happy with my choice, but if the weather is good I will certainly regret the Cups, specialy on the GP track .

Approached a Michelin engineer with these questions and according to his comments and my personal evaluation of the PSS the standing water capabilities should be on par with the PS2. Dry grip has increased and is pretty close to the Cup tire.

If its equal to the PS2 in that respect then its good enough 

Anyone have information when the PSS will be N rated? 

Mike, I find that interesting regarding CGT tires. Are you preventing from buying tires that are designed and manufactured according to present day standards?

Looking at the treads on the PSS , they do not seem to have such a good deseign to evacuate lots of watter.

Most likely sometime after the 991 is released, and available sizes for other versions may also be limited initially as well.

Yes, N rating will be offered with 991 and subsequently for the previous generations. Nonetheless they were very confident in recommending the regular PSS for the 997 as it was one of the development cars for the tire.

Regarding hydroplaning, the 911 is certainly one of the most critical cars in that respect due to the wide rear tires.here are some controversial comments around. SportAuto tested the tire and achieved a higher hydroplaning speed than on the competitors, some other tests rated it rather poorly but not worse than other highperformance competitors.

I will be doing just this in a few weeks; taking off RE050s and installing PSS. Will report what I think... But usual problem is comparing old tires with new... Most of us have difficulty remembering what the worn ones were like new.

 

4trac: Are your RE050A N0 or N1 rated?

Yes.

Carrera GT tires are 2003 engineering levels and developed specifically for the car.  Too bad the tire manufacturer only molds these tires every 4 or 5 years.  Not only are they frozen in time from a technology standpoint, they are also very old chronologically -- sitting in a warehouse, slowly turning into high-durometer low-friction wheel ornaments.

That's actually a beef I have with low-volume hyper-performance cars like the Carrera GT.  The extreme performance is highly dependent on tire grip.  If fresh tires become unavailable, the performance of the car asymptotes toward the very ordinary.  One would think that keeping a company's flagships in good repair would include a commitment to something so important to their performance -- like tires. 

Maybe the tort bar is keeping Porsche from doing all it could

The RE 050 tires are N1 marked. These were original on our 997.2, however had already 12000 km when we purchased the car, or about half tread depth.... Should still allow me to compare with the new PSS. BTW, like a few others, I have no gripes with the RE 050 tires in terms of performance as a road tire, but find them very loud specifically on chip-seal roads that have a rougher surface... owners living in places that use only full hot asphalt to build roads may not hear this noise.

True. The Bridgestone are loud on rougher surfaces. 

I look forward to your commnets re the M-PSS, in all those areas.

Or maybe the tort bar should make Porsche do the right thing and insure that appropriate tires are available for its flagship sport car. With all that power and no electronic stability system, tire performance is critical for safety.

Today, I changed my Michelin PS2 tires (F-245/35/19 R-265/35/19) which were pretty worn-out with Michelin Pilot SS tires (F-255/35/19 R-275/35/19). First thing I felt immediately was the softness of the PSS. They are more comfortable and more confidance inspiring. Also, more quiet

I am not the expert here but does above mean I can change from a Cup tire (original fit) to a PSS and have a similar performance to the Cup ? I am not asking for the same - but of course this would improve wet-handling against the Cup...

Big cock up between Porsche and Michelin, the latter is the official supplier of tyres for the whole range and the Supersport was gonna be introduced with the 991, but Porsche decided last minute that the tyre was too sporty for the average client!!!

Result: All 991 are fitted with Pirellis so far. 

I thought the 911 was a sports car...

I have them on my GT.

They're a good compromise, not as good as the cup on trackdays but better all round especially for the road. The Cup tyres need high temperature to be sticky.

I'm probably gonna fit them to my 4.0 whose Cup tyres are cooked after only 600 km!

Interesting!  This would explain the delay in approving the tyres for N-rating. 

Tyres for high performance cars are always a compromise between conflicting characteristics. Since "sportiness" will be expected of the tyre, "too sporty" can only be an euphemism for some of the tyre's other, more mundane, properties not being up to the standard required when fitted to a Porsche.
Since these could be such things as ride comfort, wet handling, noise, durability, etc., which are not exactly trivial, it would be understandable that  Porsche would want to get them right from the beginning.

thanks Futch - I will try them this spring on the RS - since i am driving the car regularly on the road I don't need to worry so much about rain...

Fair enough.

It's just a shame Porsche screwed up the timing and Michelin is not even approved so far on the 991!!!

That tells volumes about what PAG thinks of their prospective 991 customers... and why they 'tamed' the 911 driving dynamics and came up with the 991. Telling indeed!
