I've run Michelin Pilot Super Sports before on my previous car and loved them.

Therefore I myself wouldn't put too much emphasis on that aspect of tyre selection (not saying you are) and just trust the fact that any tyre with N spec met the requirements set by Porsche for it to get a release and carry the N.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I would appreciate some insights regarding the following:
It is time for new rubber for my 40th anniversary.
I have the stock wheels in place. Michelin options are limited due to the 18 inch wheel size.
I think that I will purchase the PS2’s but I have the following choice.
Front ; 225/40/18 - N3 vs. 235/40/18 N4
Rear : 285/30/18 N3 vs.295/30/18 N4.
So, if I want N4,I need to get a slightly wider size.
I am not sure what the differences are between the N4 and N3 but based on the N designation, there must be improvements to warrant the higher N number.
Will the larger tire size work?
Thanks.
Have you considered Michelin Pilot Sport 4S?
I just put them on my 996.
I went with:
Front: 225/40R18 92Y
Rear: 285/30R18 101Y
They handle great!
Much better than the Bridgestone Potenzia S.04 Pole Position that my car previously had.
I've run Michelin Pilot Super Sports before on my previous car and loved them.
I believe the 4S is superior.
Thanks.
I did think of PS4.
The Michelin site shows that the widest width for the PS4 in an 18 inch is 265 (265/30/18)
Are you sure that your rears are 285’s?
I just put Michelin Pilot Sports on mine, same sizes you need. So far I love these tires! Disclaimer: Discount Tire had to replace one of them because it wouldn't hunter road force balance under 24.
Wrt to the sentence in bold. The reason(s) for Porsche to develop a revision of tyre spec are diverse but most probably not with the intention to make it better over the previous revision, certainly not when the model the tyres are intended for, is no longer produced.
Most often it is the tyre manufacturer approaching the car manufacturer with the message that a certain compound will be phased out or at least its recepy altered due to certain (levels of) raw materials being prohibited (think REACH) in the future or certain (higher) levels of rolling resistance and rolling noise emission no longer allowed to be offered even as a replacement from a certain date onwards (EU tyre regulations dictate this for example).
As such the challenge Porsche and the tyre manufacturer often face, is to maintain the hitherto characteristics (and there are many criteria to fulfill) or at least make sure that a reduction of performance in a certain criterium is acceptable considering the overall performance of that development spec before the next revision is signed off and released.
Therefore I myself wouldn't put too much emphasis on that aspect of tyre selection (not saying you are) and just trust the fact that any tyre with N spec met the requirements set by Porsche for it to get a release and carry the N.
Having said that, I believe the wider tyres are 997-dimensions, correct?
If so, that would have me worried about tyre clearance (in all directions) and I probably would choose the 996-spec dimensions.
Nice! You obviously have summer and winter set up then. Glad to hear you don�t have issues with 225/40/18 front with 285/35/18 rear. I�m installing Michelin ps all season 4 with 285/35/18 rears and 235/40/18 front. I was going to leave front at 225/40/18 stock size but wanted to minimize the difference to larger rear size from the stock set up.
Cheers!
