Mr bc, where are these tests ?

The PS4S is a ultra high performance tyre which also works in rain from cold. Offering the best wet braking and highest aquaplaning wet speeds for a uhp summer.

The p-zero is not a uhp tyre, so they don’t get tested together most times.

But subjective feel is key the ps4s turns in on a knife and the wet performance for a uhp summer tyre is amazing.

I have ran every brand, I also have binned new p zero and Dunlop’s as I hate both brands of tyre.

Ferrari use p zero on they cheaper cars, but the super sports and ps4s on the top end cars, like wise BMW do the same, crap tyres on non M , but on M most are PS4s.

Also every ring test is on cups, even my golf uses a N0 cup.

And last as other have said the ps4s works 1/2 worn , I ran good years and while I liked them , they went to st 1/2 worn :-( so had to bin them,

I also tried the N1 p zero over the very hated N0 utter fail of a tyre and it is a better tyre, but still seems to lack feel and hops about, it’s a nasty tyre to drive hard with, my last 2 Porkers came on p zero N1 and it was very disappointing.

When Porsche did the T , you will note all the press cars were on Ps4S over the normal p zero, and the T got great driver reviews, funny they went ps4s on the T when the S was on p zero ! To make the T feel more sporty.

Last Porsche fit p zero I guess as they must be cheaper to buy, it’s that simple, but on their performance cars fit proper tyres like Ferrari and BMW do on their higher end stuff.

I did a bit of a hoon last night it was wet at 8oc and just fitted another new set of ps4s and the car hooked up still and my passenger was gob smacked what the tyre could do.

What I do fine with ps4s is they need 500 miles to run in, new they feel bad, and most tyres need 100 miles, the ps4s needs a lot of miles to bed in or loose the fitting oil, I also tend to have to run a ps4s 2 psi lower than the door cards state. But all my cars are a lot lighter than normal models and load ratings on cars keep going up :-(

Good year do have the new super sport range now, but not much known and no ones fitting them oem, but they have upped the game a bit. But why risk it over a PS4S or a cup2 !

Just looked on BC web site and it does not show PS4S 265/35/20 as being N rated the 235/35/20 are N rated .
I have the Pirelli on the car at present came with them al NO rated ,I know the consensus is that the Michelin is a better tyre but the Pirelli has a better wet rating strange. I will keep them on the car as 4/5 ml left and not likely to be using the car in the winter months so seems a pointless exercise changing at this time .
I suggest you go back and have a proper look on the Black Circles web site and perhaps scroll down the page a little as the N0 265/35/20 are listed. I wouldn't have replied to this thread that PS4Ss were available as N0 rated in 265/35/20 if they were not on the Black Circles web page.

Agreed. I always think it’s funny that non-GT customer Porsches come on Pirelli or Goodyear yet the press cars almost always run Michelin.

The one exception was my 992 which came on a. pirelli that was actually very good. It was labelled NA0.

I can't imagine the other manufacturers were particularly keen to have their products tested against one from a manufacturer on their home test track. In fact as far as I'm concerned, the entire test is suspect because of that issue. I wouldn't be surprised if Pirelli refused to take part.

agree I see people in £60k cars who garage queen them at 2k miles a year and run 10 year old Pzero hard and cracked !!!
very odd people are, again proves most cars are lifestyle objects not driving machines.
Mine is a daily, I’ve got two choices in the morning, one 15 (ish) mile deserted country road or a slightly shorter route down the motorway. I don’t take the motorway.

@slippydiff you’re right about that. I’ll get it done when the rears are ready which isn’t too long away!

That was precisely my first thought, but being as Continental didn't come first in every discipline, the track clearly didn't play solely to their product's strengths. But ultimately, the test should have been carried out at the US equivalent of Millbrook proving ground or somewhere similar to ensure the venue wasn't biased to any company's products.

Pirelli's products not being included is a bit of strange one, but neither were Bridgestone's.

I'd like to try the new Goodyears. I used the original F1's 20 odd years ago, and they were brilliant in the wet (and I do mean brilliant) though they lacked some precision in the dry.

Two points on this, both subjective.

If PH numbered posts, then #5 may explain some of the issues faced by the OP. We had a 981 non PASM Boxster which we specced with the smaller 19” wheel to add compliance. It maybe the 20” wheels are not helping the issue of noise and harshness.

Tyre manufacturers. In the summer I swapped out the OEM Dunlops that came on the Touring for MP4S. For all round road use the Michelin is a better tyre certainly in the cold and wet but at the time with temps around 20°C the slightly less immediate turn in on the Michelin was the thing I noticed first.

Pirelli don’t make a uhp tyre that’s why.

The pzero goes up vs the PS4, and while most people think a PS4 is a PS4S , it’s a step down the performance ladder.

The new super sport Goodyear’s look a great option.
But why use a mitchlin name is odd.

I did email the tyre review guy and asked about new tyres as the PS4S, not PS4’s :-) imo take 500 miles to scrub in and he did say they scrub in new tyres before test but not big miles.

I has super sports on day of release and again same with now 3 sets of PS4S, the run/scrub in is real, thought it might have been a 1 off but 3 sets in they need a lot of miles on them
What’s amazing is the PS4S while class leading is an old tyre now and it’s replacment is due lol so roll on the PS5S.

So imo the PS4S will do better than any tested tyre due to the VERY long scrub in period.

If you look at wet braking and high speed aquaplane tests it’s such an amazing thing the PS4S, for BC to poo poo my post and not back up his claims says a lot, another life style arm chair expert.

This brings the whole old tyre/new tyre comparison into the equation.
An old, though legal tyre may/will have more grip than a brand new, unscrubbed, covered in release agent tyre.

As 911R says, a fairer test would be to compare the two tyres after the new one has done at least 200 miles, and maybe even 500 miles. The issue there being that us humans are amazingly adaptable, and 500 miles into the new tyre’s life, most will have forgotten what the old tyre felt like on turn in, and will have become accustomed to the characteristics of the new one.

My experience of various Michelin’s over the years indicated they have a far wider window of performance, and are more tolerant to variations in pressure, that in turn means you can experiment with pressures to improve their turn in, without compromising ride, noise and their durability. Pirelli’s don’t have anything like such a wide window (if any in my experience) and once run outside the suggested pressures, they’re performance is heavily compromised.

The NA0 rating is a new refinement of the N rating system. The A indicates that it is N rated for 911. There is now NC for Cayenne apparently. Presumably other models will follow.

A pet hate of mine is people who write PS4 when they mean PS4S.
(Or PS4s when they mean PS4Ss)

I accept I’m being a pedant but the PS4 is a different tyre to the PS4S.

Precision in all things please.

Mine also but I do write ps4s as I cannot be arsed with caps on iPhones it’s too hard to do , I never Write ps4 when I mean ps4s
If I mean PS4’s I’ll add the exclamation mark or say PS4.
So I blame the apple keyboard. Imo nothing wrong how I write it.
Apple put caps in when it feels like very annoying.
Ps4s is how Apple does it PS4 Apple converts it to caps.
Is a ps4s a PS4S yes just takes twice as long to write.

Agreed on both the old/new tyre comparison and that it is easy to forget what the previous tyre felt like. Ironically, the MPS4S are at 3.5k miles which is almost exactly the same state of wear as the Dunlops were when I changed them and now seem to be just "normal".

Anecdotally only, I seem to recall when the MPS4S predecessor Supersport were being tested a few years ago, one of the Porsche testers had some negative comment which resulted in the Michelin not getting N rating for the 305 size tyre. High dudgeon and Gallic flounce all round, allegedly.

And though I wouldn’t have them out of choice, the Pirelli managed to get me over the Alps in cold conditions and then later that afternoon saw 300kph on the A7 towards Memmingen without running off the road. Drive according to the conditions I guess.

Gallic flounce ? Are you sure ? I mean the French are normally so pragmatic in all matters, you only have to look at Macron's behaviour with regards to Brexit, UK fishing rights/territories etc. Oh hold on second ... biggrin

Must be hard being a motor manufacturer looking for tyres for your next high performance variant. You've the option of French flounce, or Italian histrionics. Or ze dour but no doubt efficient Chermans.

I did not look that hard as it up vs the normal PS4 in most tests, as I stated the p zero is not a uhp tyre. And in modern tests it’s not in them for ultimate summer tyre tests.
Having run all these tyres and every makes on all my cars side by side the difference in the real world is massive.
At the end of the day the N0 p zero is unforgivable st, the N1 is usable and loads better but vs the PS4S it's not even close.

I'm afraid you see the world in black and white - as this most recent test referenced above shows the differences between top tyres are not massive and no tyre has everything you might want. The world is grey - even on black circles.
