Pirelli P Zero cracking
Discussion
I have just noticed both front tyres on my Cayman GTS (Nov 2014) have developed cracking to the full circumference to the inner groove. There is nothing noticeable on the rears. I have sent an enquiry to the Pirelli website, had an acknowledgement, and await a formal reply. They are the original tyres supplied with the vehicle and have covered 11.6K miles. Has anyone experienced anything similar. I intend to query with the Porsche dealer once I have a response from Pirelli.
Spooky, go and take a look at the Cayman GTS thread, sounds like everyone has 'faulty' tyres including myself.
Honestly, I just thought it was normal wear/deterioration until it was pointed out in the other thread and until Pirelli say otherwise, I'm kind of still convinced as I vaguely remember similar with my Michelins on the TT.

The manufacturer date for both the fronts is 3014, the rears which have no obvious cracks are both 3714.
The older type that you have are renowned for this and Pirelli were replacing them all FOC due to lots of problems.They have superb costumer service so call them directly in the UK and let them know your issue. They should be helpful.

Hi normal age cracking, have a look at date or DOT numbers,to work out manufactured date.The Pirelli and Bridgestone are the worst at cracking.
Just replace them
I disagree. Unless the tyres are very old, perhaps 6+ years, the rubber shouldn't crack. This was the view of the Pirelli engineer who inspected my cracked P Zeros which were 15 months old at the time.Just replace them
In 40 years of motoring I have never seen this in any other tyre on any other car.

They're not great tyres, even the new version is terrible in the wet.

It's a well known issue with the pre 2016 year p zero. They've changed the ingredients since. I had them on my 991 GTS where as an N rated tyre they are the only choice in that size currently hence people have to have them if you want N rated.
They're not great tyres, even the new version is terrible in the wet.
In 40 years I've never had Pirellis before on another car. I've noted my wife's 2016 X1 has Pirellis, but they're not P Zeros so fingers crossed!They're not great tyres, even the new version is terrible in the wet.

Hi just had an 08 Cayman in for repairs, tyres dated 1215 and fronts cracked all the way around, to such a degree i could not roadtest the car.
I suspect 30% of cars i have in for work have some sort of cracking visable.

That may well be the case, but it doesn't make it "right". A tyre shouldn't perish/crack in the space of three years. Or in the case of the car you alluded to, two years. I suspect 30% of cars i have in for work have some sort of cracking visable.

As for the general comments about Pirellis generally, I concur, they are hopeless.
As the late, great James Hunt esq once said during his commentary on F1, "I wouldn't use Pirellis on my boat, let alone on an F1 car...."

Of course it's not right, but all companies make the odd cock-up - including Porsche. It's how a company responds when they do get it wrong that is a measure of a company. And Pirelli have responded very well.As for the general comments about Pirellis generally, I concur, they are hopeless.

And Pirellis being "generally" hopeless flies in the face of most independent tyre tests. The latest test in this months Evo of high performance tyres, for example, show the PZero a good second to the PS4 (the PZero had better all round grip, but less feel) - the Goodyear F1 was a distant 8th. Those aren't the same tyres as might be fitted to our cars - but it does show that Pirelli do know a thing or two about tyre design.

Ahh, it's all going pear shaped now...
You're obviously a man who likes to do his research (actually the Germans have a rather lovely term for individuals such as your good self)
But I digress, how about you spend the next week or so ploughing through the numerous old posts on here using the search terms Porsche, Pirelli, sh*te, cr*p, useless, hopeless, no grip, car now much improved/much improved dry and wet grip now I've fitted such and such brand (not Pirelli, obviously, though more often than not Michelins), wouldn't fit them again, poor grip in the wet, noisy, intolerant of small pressure deviations, dire when partially worn, poor wear characteristics.
And rather than contesting what many on here see as an incontestable fact by using "independent tyre tests" as your point of reference, see what the great unwashed on here think of the Pirelli products when fitted them to their cars.
Furthermore, in my limited experience, your much heralded independent tyre tests rarely utilise the cars most owners on here would actually fit the tyres to. So testing the latest all singing all dancing Pirelli performance product on a Golf R and an Audi A8 quite frankly means nought point nought percent of chuff all when it's fitted to a rear or mid engined Porsche product.
And finally ...... Some years ago Evo emailed me to ask if they could use my M3 CSL for one of their features. I agreed and got to experience my car being driven at a seriously impressive pace across the backroads surrounding Goodwood, by what I consider to be one of their best writers. Having done so, the owners of all the cars and said scribe decamped to the cafe at Goodwood.
As breakfast was devoured, the subject of tyres came up. Three members cars has Pirellis fitted, and Evo's scribe referenced one specific car (the 22B) and said it was somewhat hamstrung as a result.
Concurring, and being a straight to the point type of individual, I said I thought Pirellis were, on the whole, utterly hopeless. Strangely enough everyone present concurred, except for Evo's member of staff, who remained tight lipped.
"So *********, what's your view on Pirellis" ? I asked. "Or would you rather not comment on the basis your magazine runs their multipage mini articles/infoadvertisements every month....." ! ! Said individual looked directly at me, said nothing, but smiled a knowing smile..... nuff said

Proof positive then...You have accepted the (statistically insignificant) view of a small number of individuals - and made inferences which suited your point of view. I can trawl through any number of tyre tests (not just Evo) which suggest that Pirellis are competitive. Not necessarily the best - but NO tyre manufacturer ever comes consistently top - and in any case what an individual prefers depends on their priorities.

Personally having tried N1 PZeros and preferred them to Eagle F1s, I'm not prepared to dismiss the Pirellis (I always prefer my own experience - since it reflects my own priorities) . Do they meet my priorities better than Michelins - don't know, and I'd like to find out.
There is a lot of rather unscientific prejudice in this world - and when anyone says a) is crap and b) fantastic (in the case of closely competing products) , I suspect prejudice rather than scientific analysis.
