I still have a car with P-zero it lights up in 3rd in a straight line , useless !!!

I have ran 2 other cars with PS4S over winter no issues, it like driving in the dry.

seems a shame to ruin a GTS with poor tyres, but people do think I am mad binning 3 sets new tyres ! but I love my cars and for £800 it seem a shame to ruin them on a £80k to £120k cars.
if i hadn't experienced it for myself i would have thought you were grossly exaggerating.

but i can only agree the difference between the Pirellis and the Michelins is indeed night and day. Even I can tell and I'm no Hamilton but in the wet and/or cold especially is where the Michelins are a joy and the Pirellis - i will agree again - are just plain dangerous.

i had 2 nearly new Pirellis on the rear that were on the car from when i bought it, and 2 brand new fronts (with labels still on) that Pirelli replaced due to the cracking issue. I haven't binned them but they are in the loft and will only see the light of day again if i either bin them or sell the Cayman (which is unlikely unless something goes wrong), in which case I will put them back on.

I assume you are talking N0 - N1s are very different in cold conditions

Sloppy individual that I am I spend most of the Winter months on VERY suboptimal tyres. At the first sign of frost I put on my winter tyres and keep them on until spring (just about now). Of course I should swap them for my Summer N1s on a daily (sometimes hourly basis) which are VASTLY superior once the temperature gets near double digits. But I don't.

What you are suggesting may make sense for a weekend hoon/trackday car but for those of us who use our cars as dailys it really is getting a bit silly.

my Clubsport had the new ones, The car was usless putting 300bhp though the front wheels my dash was like a christmas tree , PS4S transformed my Golf Clubsport.
And as I said I ran it though winter and in the snow, was quite shocked how great they were on the Golf in the winter.

so while the new one may not go hard and crack, they are a poor tyre vs the PS4S.

I see you did not rely to my MPSS and PS4S lack of reviews in EVO tyre test over the last 10 years !!

many 718 owners have P1's and hate them already. lol I think you are on your own which is odd having suffered the P zero and trying to get new tyres from them.

Saw a car in the ditch yesterday, be interesting to see how many car crashes on bends have P zero tyres on them.
normal bend as well so I do wonder what the driver did to find the ditch.

Most cars seem to come with the P zero !

My mates just got the new 911 GTS and the backs twitching on that car a lot to a point he asked me about tyres ! and wants new ones one his £120k car to enjoy it.

I did not reply to your comments on Evo because there was no need - there are other independent tests (Road and Track for example) which do compare Michelin ps4s and Pzero PZ4 . The conclusions of independent tests are that yes the Michelin is the better tyre (which I have never contested) but that the Pirelli is a very good tyre indeed. I'm not sure whether Evo are under any more pressure than all the other magazines -none are keen to upset advertisers. Clearly they didn't feel they had to say nice things about the Goodyears!

Personally far more inclined to take the views of magazines as the result of instrumented tests than opinions here.

See I don't trust reviews as every one is on a back hander these days once money is involved.

I bought a 350Z off reviews (all were raving about it at the time) what a pile of st that car was, sold it after 2 months.

here you go, best summer performance tyres.

https://youtu.be/QseDx-aBaK4 king of tyres PS4S :-) Good year he rates 2nd.

I asked about the p zero on his site just got an answer "did not make the cut"

"No, the PZ4 is a good tyre, it's just not quite as good as the other tyres I mentioned at the start of the video for the price point, so didn't make the final cut. "

Interesting video, I notice he is surrounded by stacks of Pirelli tyres in the background but does not actually mention them once. Must be all 911R's cast-offs ... :-)

Not sure why you quote this test - the Pirelli doesn't get a mention - it clearly deserves a mention if only to diss it. What he does say is there is almost nothing to choose between the PS4 and the PS4S - and when Evo tested the PZ4 against the PS4 in instrumented tests there was nothing to choose between the Pirelli and the Michelin in outright grip (and I know they must have been bribed to measure this) Ergo Pirelli and Michelin are pretty much equal on grip (both wet and dry).

Where they aren't equal from what I have read is

1) The Michelin has better feel - and would be the reason I would tend to favour it BUT
2) It's noisy - and since this is already the achilles heel of the 981 that would be a concern on a DD

And if you want a nice quiet comfortable allrounder and weren't too fussed about outright grip you might choose the Goodyear.

if you want a nice quiet comfortable all rounder you don't buy a Sports car in the 1st place lol if you do, you want it to have a bit of grip and feel from a sporty tyre. But more so be safe in all conditions !!!

you say "the Pirelli doesn't get a mention " that's because he stated he IT DID NOT MAKE THE CUT !! it was a review on the BEST summer tyres :-)

enjoy your P-Zero's , I can only offer up so much advice and then give up to be honest. I run a lot of cars and I buy a crazy amount of tyres.
I'll give tyres a go(who wants to bin new tyres !! ) but have no issues binning new tyres if they are st, that does mean 3 sets of P zero and 1 set Dunlops binned and I did bin my F1's 1/2 worn as they went off big time at 3mm.

I was forced to ditch the P zero on my M3 for MPSS as even in the hail I could not get up my local hill and had to wait for the hail to melt !!!
caused a hold up being stuck on a small incline !!!.

we have 5 or 6 people on this thread all hate the tyres and agree that my comments are not out of context.

If the tyres were even a little bit good I would stick up for them but M3, Golf , Porsche I have had to remove the stock tyres.

And what's funny, every tyre fitter I have been too has not even been shocked I am binning them, they agree that the brand is rubbish.

10-15k miles on a weekend toy, equates to them being on the car a long time. Hence the reason I've ditched perfectly serviceable sets of tyres and sold them and then invested in what I considered to be the best available option at the time. That was never a product manufactured by Pirelli. As I said, it's pointless owning/driving something as focused as a Mk1 996 GT3 and have it hamstrung by tyres that neither inspire confidence, nor grip when called upon to do so.

No Porsche I've owned, except my first 996 GT2, was used as a daily driver, for that role I've owned several oil burning BMW saloons, the last one racked up 120k miles during my 4 year ownership, all were run on Michelin tyres, apart from a moment of madness when I purchased a set of Continentals, they were wonderfully quiet and smooth riding, but I've pushed supermarket trolleys with more front end turn in bite. And to add insult to injury, the rears lasted no time at all compared with the Michelins.

My Winters came off a couple of weeks ago, driving the car in the various bouts of snow we had was highly amusing as the car coped admirably with the inclement weather, much to the annoyance of the massed ranks of ill-prepared Mercedes and 4 X 4 owners ....

Been driving a 718 equipped with Pirelli's recently, awful hateful things!

I would strongly advise anyone who has Pirelli's on their car to ditch for MPS4S, hell even just get the Goodyears if you can't source the Michelins (they're not the best tyre but they shouldn't kill you).

We are obviously coming from a different perspective. To me a 981 is a wonderfully rounded DD sports (in may case) coupe. If I wanted a SERiIOUS drivers car I would (and have) gone to Lotus/Caterham or (if I was really mad Radical). So(for me) to get fixated about the last 2 or 3 % of grip is simply to lose perspective. I want a car that covers all bases- a jack of all trades - but inevitably is master of none. It means I will feed ride/noise/life into the argument of "best" tyre. Even then Michelin may well come tops - but I wouldn't guarantee it for me - and how I will use the car.

You site Contis as dire - currently much in fashion and well regarded, so to get fixated about best at one point in time doesn't make sense to me.

This is all of interest to me, having been pretty sensitive to my tyre choices.

My findings.....
PS2 was an epic tyre, but too stiff for the camber settings on the rear of a 130i. Steering was amazing!
Goodyear were more flexible, so gave a good footprint, so had better traction. But they always felt dull and inert, like having a duvet wrapped around my wheels. Also, I also wasted a fair chunk, buying the ste far eastern market versions, that Goodyear denied were ever imported. I tend not to trust them anymore, as they lied to me frown
For that car, PS3 were the best chassis, grip, feel and ride compromise.

The 420lb/ft 135i made mincemeat of the PS3 though. No traction at all.
The Conti CS3/5 were also short lived.

I then tried P-Zero MO and the car was transformed for the better smile
Good traction, direct, almost PS2 steering and progressive performance wet, or dry.
I bought loads of them, as I only ever managed 7-8k (from any brand) on the rear!
None cracked and all wore evenly,

Our X73 981 GTS came on the N0 version and I still found the same. But this time thay lasted nearly double the mileage, which the same mix of driving.
I repacked with more as required.
The only negative I found, was the car really hated new rear tyres! It took a good few weeks to wear them in. That could just be the CGTS though.

So, the incoming Cayman 718GTS will shod with N1 versions and I’m approaching them with an open mind.
The 718 GTS is PASM only and pretty well worked over. Very different to the X73 981.

I expect to start again with my opinion/findings. I’m looking forward to it and grateful I’ll not be getting any Goodyear tyres!

Not all current experience I know.
Always used matched sets of four.

How opinions differ smile

Indeed, but nothing new there.

I'm sure a 981 would make a wonderful daily driver, but not if you're putting 25-30k PA on it, such mileage would be pretty much guaranteed to reduce its value fairly dramatically.
I viewed a superb example in GT silver at OPC Bristol a couple of years ago, I test drove it and thought it delightful, so much so I considered it as a daily driver, but then realised that clocking up 100k miles over 4 years in a car that already had 42k miles on it, wouldn't be prudent financially.





Personally I much prefer to open the garage door to something truly special, tactile and engaging on a Sunday morning, and for me, the 981 is a far cry from being that.

Each to their own, I have no interest in anything Lotus, Caterham, Westfield or indeed radical have ever produced, and never have had. Their like is better suited to use on track, sprints or hillclimbs than on the road imo.

They were, but those Continentals went on a car at least 5 years ago, I've not revisited the Sport Contact range since, instead I've moved on through the Michelin range, currently using the PS4 and SuperSports.

Swapped from P Zeros to Michelin PS4S . Great change in handling and grip.BUT p zeros lasts 10000 miles at least and handled 4 track days incl spa . PS4S lasted on fronts 1000 miles with only 300 track miles and delaminated on the fronts! No screaming tyres or back end movement but fronts surprised me. Replacing them and then a good chat with Michelin . Spend a lot a year with them and will see how they deal with this. Anyone have a contact with someone with understanding in Michelin? The tyre has a racing flag on the sidewall. ??
Ok that's pretty unusual I have to say. Without you mentioning the brands, I would fully expect the Michelin to have lasted far longer even with trackdays and the Pirelli front to have delaminated. In fact that was exactly my experience on a Mclaren, 10k miles with a decent number of trackdays and Pzero corsas front that delaminated after 2 trackdays (which I have not known to happen on a Michelin high performance tyre despite having seen Cups run to the canvas multiple times).
