Another question about N rated tyres

No, Porsches bulls
t rings hollow, that tyre will have been made for the CGT. It's Porsches recommendation to fit it to the Cayman.
In this particular case it is optimised for the CGT but that does not mean it's any better or worse than any of the non N-rated tyres also available for the Cayman.t rings hollow, that tyre will have been made for the CGT.

Marketing and money and tie in's, Michelin are a business they make a lot of money from Porsche
they may well have a team to make N spec but Porsche pay well for it otherwise why bother.
just a shame all the N spec tyres are about 5 years old, and times have moved on.
As conti, goodyear, bridgestone, Michelin , Pirelli all make N spec not all can be the best tyre for the car lol
hence again this bespoke rubbish talked about is daft as all 5 tyres will be miles apart in how they work.
And PSS non N spec will still be a faster/safter/better tyre than all 5 brands current N spec.
I am sure the Michelin Man would say his tyres are better than the other 4 companies tyres and the same from any of the other 4.
Hence how can Porsche pick and choose which tyre is best, they must tender out a price and pick the cheapest bulk buy that day
you will see Pirelli for 4 months on new cars then goodyear for a few months.

how do we know the PSS for the CGT is not just a normal PSS with a N badge on it ?
It's going to be better than the org tyre for the CGT but now Porsche can sell a tyre which works.
yes time spent making that size and Porsche fitting and testing it to a CGT but it might just be an off the shelf tyre compound and the only thing "tailored" were the right sizes.

It "might" be, but communications from Porsche and Michelin suggest otherwise.It's going to be better than the org tyre for the CGT but now Porsche can sell a tyre which works.

There's more evidence to support some tuning for the CGT than your claim that there is none....

Clearly that's not true, as we have just highlighted above that certain tyres were tailored for the CGT, certain tyres were tuned for the 991 GT3 and have in the past been tuned for the GT3 RS.
There is no evidence that the SS was altered in any way, these sizes were in the market and being used by CGT owners, I recall it was one particularly irate and well connected CGT owner who complained very loudly at Porsche hierarchy that the N tyres were dangerous on his CGT and it was ludicrous that Porsche would not "sanction" use of the much better SS which transformed the CGT..... The SS's in that size got the N stamp.TB993tt said:

You may choose not to believe it, but the evidence is there:http://press.porsche.com/news/release.php?id=805

We have both Porsche and Michelin claiming that the MICHELIN tyres for the PORSCHE CGT were specifically tuned for that car.And we have 'some bloke' off the internet with an ego the size of Brazil who is claiming otherwise (with no evidence to support that claim).
I think we know where the 'brain dead nonsense' arises....

^ This... It all seems to be getting a little over thought. I'm paraphrasing a little, but it was basically explained to me that the compound/construction/tolerances that a particular tyre is built to, allow a vehicle to demonstrate all the characteristics that Porsche would want on that particular tyre.
That in no way means that an existing CGT tyre could not also be fitted to a Cayman and allow the car to perform as required.
It just means that when they were looking for tyres of a particular size, it was found that this existing one ticked the boxes and allowed the car and to display the characteristics desired, even though the initial spec was developed for another car. Whether its load rating is different or its used on the rear rather than the front is neither here nor there. What is important is that it ticks the box to meet the requirement for that particular application.
The addition of the N-rating just denotes that it is then built to the same compound/construction/tolerances as the one that was tested.

I don't even know how Pirelli Pzero's got the N rating they are really bad on the car.
again proves a point that Porsche buy what's cheaper when they tender out that month for 3000 tyres.
Porsche have to pick more than one OE due to supply. It wouldn't look great if they just chose the one tyre manufacturer, only for that manufacturer to have productions issues and no one able to get their tyres (I believe this just happened on the 91GT3!)again proves a point that Porsche buy what's cheaper when they tender out that month for 3000 tyres.

From 2 seperate owners I've heard this as well that the CGT SS tyres are standard supersports just stamped with the N tag and made in 335/30 20s for the rears.It is good press for Porsche to claim that further work had gone into developing specific N rated tyres for the CGT but purely on economics, there is no chance PAG would bother to go through all the hassle (and expense more pertinently) of developing a new custom tyre for a 10 year old car that had a 1270 production run as they would never get the money back especially when there is a more than suitable off the shelf solution.
The tyres are tweaked to match a car it may not be a great deal in some cases and a lot in others. The construction may be different if a cars geometry is such that it puts more load on a tyre on one edge than another.
It never ceases to amaze me that some people bang on about getting a geometry set to their driving style but still within manufactures spec and it transforms the car. On a Porsche 997 Turbo the camber tolerance is a 1/4 of one degree on the front and toe is plus or minus 5'. So bugger all tolerance really, but people claim its transformed their car. I read that camber changes on F1 cars are made in increments of 1/4 of a degree or more as less than this could not be of any advantage.
My be heaven forbid that some drivers are just not good enough to be able to tell the difference between like for like tyres if one is a PS N tyre and the other is just a PS.

I think people who have the geometry set to their driving style DON.T do it within manufactures spec
most people who post here have a none OEM geo other wise we would all be killing our front tyres.
then quote "transformed their car" :-) both mine run out of oem spec and it has "transformed my cars" :-)
