Pirelli P Zero Tyres - Premature Cracking

[Avantime]

I bought. Second hand XFR-S with Pirellis all round. The fronts were cracked, only noticed after I got it home. The dealer - Taunton Jaguar - we’re crap and refers me to Pirelli, who were excellent. They replaced them FOC having done 2600 miles and 18 months when I bought the car. The replacements lasted 14 months and about 22000 miles, but we’re also cracking towards the end. So not a bad batch. Pirellis crack. I’m now on MPS4.

Did Jag put the Pirellis on when the Dunlop issues surfaced?!

Mine cracked on our Sportbrake and was picked up on second service. They didn't offer to replace but suggested I contact Pirelli. I did this and they told the dealer to send them for examination. I got a pro-rata refund for a new set so better than nothing. They did not admit fault although offering the refund was the same thing surely?? I think a dodgy batch....

Thanks for all the feedback. Much appreciated.

So it seems it’s a well known issue caused by temperatures below 8c!

I’ve looked at the DOT numbers and my tyres were manufactured 9 months before the car was registered so perfectly reasonable and not extreme.

Interestingly the DOT numbers show the 4 tyres were from three different week numbers... so not the same batch.

I still can’t believe that Jaguar will sell cars with tyres that degrade below 8c. Not fit for purpose surely.

Unsure, but the R-S was developed on Pirellis.

I know of two people having all tyres replaced under warranty by jaguar due to cracking. These were both XF models with the 20 inch wheels.

So I'd speak to jaguar and ask if they have seen similar issues on your model.

Worst tyres or most overrated I ever encountered. I would put them alongside the rainsport 3s. Shocking grip, wear very quickly and too soft.

Just crap tyres. There are so many better alternatives. Why people buy the Pzeros is beyond me.

Same reason they all used ditchfinder grade P6000s for years and years and years I imagine - Pirelli must sell them to manufacturers for buttons!

Do you know what the manufacture date of the car was?

Seen that on various Continental tyres over the years. Don't think you have any comeback.

Yep, same here. Seen this on two occasions with Contis. In one case, the tread was actually separating from the carcass on a well maintained, gently driven 15,000 mile car. Continental weren't interested. Based on this, I have never bought their tyres since, despite good reviews and occasionally tempting prices.

Michelin all the way for me. Well worth the few quid a corner extra.

In my experience the Michelin's usually last a few thousand extra miles as well meaning the extra cost is a mute one anyway

Citation needed, never heard of anything like that before. P Zero is just a mainstream car tyre so I find it very hard to believe.

OP what is the DOT code on the tyres? They may already have been a good few years old before they were fitted to the car.

On U.S. Warranty used to say 45f but now just says low ambient temp, see page 5. UK data sheet used to say 8c but missing from the weep site atm.

I'd like to point out that the google snippet is referring to the "P Zero System" which is Pirellis name for the Corsa system, a more track focused tyre (Toyo are the same with the R888), and the warranty linked is for America, which has very different laws regarding tyre warranties.

I'm not saying neither applies to the current European version of the straight "P Zero", but these documents don't prove it.

FWIW, I'd put in a warranty claim with Pirelli as I think you'll get something out of them.

There was a recall a couple of years ago, albeit one they didn't publicise very hard. I got all four tyres (P-Zero's) replaced with Goodyears, by happy coincidence just when they were getting towards the wear indicators anyway. Did have to specifically ask at the supplying dealer though.

Awesome weekend car OP

Edit - checked back to see what the OEM tyres were

Seem pretty good to me. I do not agree with any of those claims you make.

Do you mean ‘moot’ ?

15,000 mile 18 inch Pirellis on our Sportbrake were replaced free of charge by Jaguar as a service recall. They were tight lipped about the issue and refused to comment if it was Jaguar or Pirelli who were picking up the bill. Local dealer highlighted the issue albeit other dealers are seemingly unaware of the problem and will happily sell you a new set of tyres.

15,000 mile 19” on 335d, about half-worn, no cracking yet, hope to get some cracking in the next half of wear!

Incidentally, my 335d was wandering a bit on Kent roads, straight as an arrow back in North Wales. st roads iI you ask me.

I can't believe that even now you have this info you are buying the same again?



I don't rate the P Zeros, Rosso's are OK but the Neros are too hard, great if you're doing 25000 miles a year, but much better tyres out there if you want comfort, grip and quiet.


I have seen this cracking loads on Continentals, I even got them out to look at them on my Merc as they were cracking after 14 months. They told me I had left them outside too much. WTF?!

I had P-Zero Corsas fitted to my car and on track they were perfect. Although saying that, the corsas and the trofeos are design for sunny track days but I do daily drive mine even in the rain and have never had any issues.

Same warranty for all p zero summer tyres.... http://shop.pirelli.com/us_en/tire-warranty

This is also US. Do you have a link to the Ts&Cs for the UK? The documents I can find for UK market specifically show no specific exclusions like that. I expect its inclusion in the US version is to stop people going out at -40˚C in wherever-creek, getting cracks, and warrantying new tyres (tires). Even in Altnaharra it's not often -40˚C in the UK. And even less often in Bracknell.

Not that I think they will payout without some squirming, but I don't think there is a blanket clause like that for the UK.

[wilwak]

I’ve complained to Pirelli and they’ve responded quickly and with interest.

I’m considering changing my tyre order assuming that it’s not to late.

What Michelin tyres would you all suggest?

Pilot Sport?? Is that right?
