Found these two tyres from tyreLeader for my Boxtser

265/35 ZR20 99Y - £194
265/35 ZR20 95Y N0 - £203

Now, I realise the N0 means 'Porsche approved' - but can anyone really tell me (not guess!) the physical difference that makes?
To me, the cheaper typre looks better as it has a higher loading (99 vs 95).

981?

95Y is the correct load rating for the rears.

99Y isn't.

NO has stiffer sidewalls I believe. At least they do in Cup 2s in the bigger sizes according to the McLaren owners.

Yes, its a 2.7 981. Did not think about the tyre wall - thanks.

I'd go for the later N1 Pirellis rather than the N0 if you can get hold of them in your size. Much nicer, more progressive tyre which produces less of the nasty tyre scrub than earlier tyre. Makes the chassis more playful and is part of the reason the 718 handles better than the 981.

Yes, for god's sake DO NOT get P-Zero N0.
I had them and they were awful, plus the fronts failed at half worn and Pirelli refunded me.
Bought Goodyears instead. Much better. But will ultimately change for "N" marked PS4 when they're out early next year in 20s.

I can echo DJMC comments. Strongly suggest that you do not buy the PZero NO tyres. IMHO, They do not work well on a 981.

I got so fed up with the acute tyre scrub when cold, the road noise and the stiff sidewalls exaggerating every uneven surface, that I binned all 4 PZeros with 4/5mm still to go and bought Goodyear Asymmetric F1 series 2 tyres (Porsche approved). The 20" rears were not easy to find but got them from Germany in the end.

The Goodyears have been a real revelation and substantially increased the enjoyment of my 981B. Does anyone know when the Series 3 F1s will have Porsche approval in all wheel sizes?

My GY F1 A2s came from Oponeo in Feb.

Tyreleader have them: https://www.tyreleader.co.uk/car-tyres-265-35-20-9...

and the fronts...

Check rim protection differences. "FP" & "MFS" ???

From what I understand you can't get the new P Zero pattern in anything over a 265 section.
I needed 305's and had to go wit the old tread as nothing else was available for my car.

I also think that since all the issues they had, they have changed the tyre compounds to make it better. This is what Porsche Reading told me anyway.

At the moment all new 911's are coming through with P Zero's old style tread.

With mine, cracking in the grooves and outer edges (NOT caused by scrubbing, the Pirelli engineer said)...

Did you look at the manufacturing date?

That's interesting, I have just purchased a Boxster S and the rears were just like that with 4mm tread left. Last year the car had an MOT advisory to replace the fronts because of perishing which I would assume would be the same now? I couldn't put a reason why the tyres looked like they were 50 years old but were 2013s and the car's second set in its 28k mile life. Shame I've just put on the same again!

XT 9K L288 4713 & 4913 on a May 2014 981. So, tyres dated end of 2013.
Photos taken Feb 2016.

Pirelli were excellent at sorting the issue. Contact info available.

Wish I'd known this 2 weeks ago! Did Pirelli say anything about the cause and more importantly have they sorted the issue? my tyres were 2013 as well.

I got a free pair of (N1) fronts - the rears were more or less worn out anyway so they weren't prepared to replace them, and it was obvious that the rear tracking was incorrect and had caused the wear.

But no they didn't say anything about the cause. Mine had cracking similar to DJMCs. Their rep did say the N1 represented a development in a different direction - whatever that might have meant. Certainly they feel very different, I'm not going to say they transform the car, but I was considering changing the rear ARB to lose a bit of the completely planted (and immobile) feel at the rear - but I'm not any more.

I have also tried Goodyear Eagle F1s (the winter wheels I bought came with practically new Goodyear F1 summer tyres on). Bear in mind that they are 18" (my normal ones are 19). Predictably they gave a bit better ride than my 19s, they also gave better steering feel than the Pirellis - but they gave more understeer, so, on balance, I preferred the N0 Pirellis, and much prefer the N1 Pirellis. But we are comparing 18 and 19" tyres so it's not an entirely fair comparison.

I dealt with Samantha Taylor at Pirelli ( samantha.taylor@pirelli.com ). Spoke over the phone to start with and sent some photos. She was really excellent at corresponding via email and arranging an engineer visit. The tyres were off the car by then as I'd already lost confidence in them (they prefer the tyres ON the car). The rear P-Zeros were worn out at this point (22k) so I'd changed all four to GY F1 A2. The Pirelli engineer examined the fronts at my house, agreed the compound was suspect and that the tyres were half worn. I expected to be offered half their new value but he understood why I'd switched to GY and without any prompt offered to pay the full price of the GYs if I could let him have a receipt for them, which I did.

3-4 weeks later a cheque arrived for the full GY cost.

When you get such great customer service it does encourage you to keep an eye on their products for the future, but I'm firmly off the P-Zero N0 model.

Yes Pirelli are known for having top class customer service. I spoke to Porsche Reading tyre guy and he said that as you mention, the compound of the N0 is different to the new N1's.
He reckoned that they'd taken something out of the tyre make up rather than added something. As long as they've rectified it, thats what matter as bad news travels very fast on these sites!

Furthermore, my option were limited to 2 tyres, the Pirelli P Zero or the Dunlop Racemaxx. The later being really very expensive and not well liked on here be many people that swap them for Cup 2's.
Just as well Pirelli seem to have have sorted the issues!
