PS4S N0 v P-Zero N1

[rianos]

Have had PS4S on my M4 and thought they transformed the car even from the MPSS that came with them and was going to order 4 for my 911 GTS but have noticed the Porsche rated versions only have a wet rating of B compared to A for the N1 P-Zero. Anyone had both that can offer opinions?

Had a bit of a moment in the car which is what made me think of changing, it could have been fuel/oil spilt on the road as I've never had any issues with the P-Zeros before but Ive only had the car a month or so and have read reviews that don't rate the Pirellis in the wet.

I've had both (20" Cayman S) and the PS4S are much better in the wet

PS4Ss get universal praise, they're the current tyre of choice for mixed weather road use. I haven't tried the N0 versions, but the regular PS4Ss on my wife's Focus RS are superb. I'll be switching to them on my Cayman (not N-rated as I'm not running the extended warranty) when the time comes.

Ive had both in 19`s on my 997 turbo. I found the P-Zeros shocking. Poor grip, especially in the damp and they only lasted 14,000 miles. Replaced them with PS4S`s and the difference was staggering, even before id even run them in. The car really grips, even in the wet. To make things even better, my 305 rears have only just worn out, after 25,000 miles of use. The fronts still havent hit the wear indicators. Needless to say ive just replaced the rears with a new set of PS4S`s and will stick with them.

Agree 100% p-zeroes (I had the N1’s) are awful in the wet.

Thanks for the replies guys, car has only done 8000 miles but think i’ll go ahead and replace al 4 with the PS4S if this is what the N1 are like in the wet.

I had a 991.2 C2 GTS which came with P-Zeros, then soon after had a 991.2 Carrera T, and that came with Michelin Pilot 4S - I much preferred them. Wet grip was marginally better, but he stand out improvement was the feel they gave

How old is your GTS?

I bought a 2014 C4s in January with P-Zero’s and noticed cracking in between the tread, I complained to Pirelli and they contributed to my PS4’s!!!

Worth checking.

Yeh but it’s the PS4S that’s really competing with the PZERO, Conti 6 and Eagle F1 Asy5, so you wouldnt really expect the vanilla PS4 to beat those three.

It’s an interesting result though for all those castigating the virtues of the PZERO. It sounds like the latest version of PZERO is much improved over the earlier ‘N0’ versions, though to be honest I never had issues with the PZERO except getting a bit squirmy in cold/wet conditions, I’ve always thought the dry weather performance (in particular) superb.

The Michelin Pilot Sport 4S is a significant improvement, and different to the tyre tested above....

[arcamalpha]

I’ve found the recent pirellis are very temperature sensitive. When it’s 25deg or more the Pirellis are quite nice. They lose the hard edge which makes them feel skittish when cold. So if the test was done in warm conditions I can see how the Pirelli would do well.

However the new “NA1” pirellis that come on the 992 seem quite a bit better even in cooler conditions. Maybe Pirelli have made some improvements.

I’ll most likely swap to PS4S as soon as they’re N rated in 992 sizes though.

N1 is much improved over N0 in my opinion.

Been on track, in wet and dry, and there’s plenty of grip there.

My P Zeros are N2, are these further improved over the N1 ?

[ellroy]

If they’re N2 they’re the latest development, so should be an improvement, these things are always a little subjective though.

Also, some sizes/models get N ratings and others don’t, despite the base tyre being available. Logic doesn’t seem to apply somehow.

[rianos]

Out of interest what would be invalidated under warranty if running none N spec tyres? I assume anything suspension related? If I'm going to change to PS4S I'm debating getting the non N spec versions as they have better wet rating and planning to increase the size from 245 to 255 or 265 up front. From what I can tell the N spec are just the same as the Audi/Merc specific versions so doubt they're Porsche specific as such (they are however cheaper oddly).

My 981 Cayman GTS was on PZero N0, which was fine. Less good in the wet, but totally predictable.
My 718 GTS came on PZero N1, which were better in every way!

I changed to PS4S N0 and the car is way nicer to drive in all conditions, especially in the wet.
Such a good tyre


Re your fitting other sizes and non NO question....
Porsche will spit there dummies, should you need to make a drive train / chassis related warranty claim. You’d have to pay for any work yourself.

Tyre rating systems are not consistent and are a waste of time at this level. No need to worry.
Michelin do make a specific N version. It is not the same as Merc versions etc.

The Michelin Pilot Sport 4S is homologated in the correct size on the 991.2, as it’s fitted as an option tyre on the Carrera T (as well the P-Zero)

I’m intrigued what improvement you hope find by fitting a non standard tyre in a wider size onto a 991.2...?

This thread makes some interesting reading and makes me wonder how on earth the Pirellis get so slagged off. I have a 3 month old set on my car (fitted by the dealer) and I think they and the 911's chassis are a superb combination! In the the last 5 years I've run many cars and so sampled on the Conti 6's, MPSS, PZeros, Bridgestone S001's etc. I should also add that I love Michelin tyres and have pretty consistently bought the latest Pilot Sport version when I had the choice. ....

However, I like the PZero's, so while I get that they may go "hard" as they get old and to me they feel optimised for dry weather (getting stickier as you make them work harder); they do have a tyre label rating of "A" in the wet where the Michelin 4S's only get a "B". I've had nothing but predictable handling, wet or dry and the 911 has surprised me with the amount of traction it generates off wet roundabouts. So I can only conclude that my almost brand new N1's are better than the earlier (and older) "N0" certification .....

The good news is that Black Circles are now stocking the Michelin PS4's in an "N0" rating - so those that hate the Pirelli's can change them immediately as long as they need or are happy with a 305 section rear. Me - I'm happy to stick with mine and blame myself for any errors, and I'll be very upset if they last beyond 10,000 miles as I certainly won't have been enjoying them or the car enough ....

The Pirellis are good in hot, dry weather. However PS4S are just a better tyre, especially in typical UK mixed conditions (the tyre label ratings are pretty meaningless). You don't really see anyone with PS4S fitted saying they can't wait to swap them back for Pirellis.
