Hi there
Right I am in the unfortunate position that my rear tyres are very low.
Currently the car is shod with Pirelli Pzero Rosso's all round which I find don't seem to be that sticky.
I'd like to hear from you guys with 911's who have experience of both Pirelli Pzero Rosso and Michelin PS2 on your cars. How did the two tyres compare, which is the better for dry/wet grip?
Now odd question, the new Michelin Pilot Super Sport is out, a tyre designed for the 911 and will be standard fit on the 991, but is still not yet available in N-Spec and its this tyre I really want. There shall be zero difference between the current Michelin SS and the N-Spec version in construction, its just a badge/sticker/approval.
In the US Porsche are fitting Super Sports for customers with no issue regarding warranty and I've even read that the odd UK customers have had their latest Turbo S also come shod with Super Sports, still with no N-Spec rating but new.
So my question is are Porsche allowing fitment of the Super Sport in the UK with no implications on warranty or if so what implications?
It just seems a damn shame to fit PS2's when for the same money I can fit Michelins latest tyre that is designed with the 911 in mind and winning so many rewards and my old tyres won't last until they come along with N-Spec sticker/approval for the tyre which is no doubt 6-12 months away.
So to summarise my questions are:-
1. Which is better Pirelli Pzero Rosso or Michelin Pilot Sport 2 (PS2)?
2. What are the warranty implications in fitting Michelin Super Sports here in the UK?

Martian O said: Also bear in mind that the Porsche Experience Centre at Silverstone use non-N rated Super Sports........... Yes very true, I think Porsche really need to make it clear here, because we have several instances of Porsche now using this tyre. 1. Fitting of Super Spors in the US and no issues with warranty. 2. Supplying new UK cars with these fitted with warranty. 3. Porsche experience centre using these very tyres, which means they are happy to run on them without fear of issues with PASM. All the above is none N-Spec Super Sports. So whats the score Porsche? Can we fit the Super Sports to our cars now without warranty implications? Normally a none N-rated tyre would be a big no no, but thats to prevent people from putting crap tyres like Ling Longs on their Porsches. This is different as its the Michelin Super Sport which has clearly been designed for the 911 and in all tests is prioving to be the best tyre out their for the 911.

Magic919 said: Do Porsche ever post responses on here? Unknown, but I am gonna ask Porsche directly and link them to this thread as I think this is a rather valid argument. Even though the Super Sport is none N-rated we know that Porsche and Michelin know its fine to use this tyre and it will be N-rated in the very near future (6-12 months), but some of us can't wait that long. Well as Porsche are selling new cars with these none N-rated tyres fitted, using them at their experience centres and given the green flag in the US I myself and 100's of others want to know the answer for us guys in the UK. UK law dictates one could fit none N-rated tyres to your car and Porsche could not deny a warranty claim unless they were able to prove the none N-rated tyres were the cause of the failure. Still this is different, were talking a Michelin tyre designed for Porsche, in particular the 911, its not like were trying to fit some cheap nasty tyre.

My understanding (I'm not 100% on this, perhaps Soovy will be along to chime in) is that the below is only true for the warranty on a new car, not on the extended warranty you can apply when the original one has run out. If I've got it the right way around, the original warranty is covered by block exemption law, meaning that there's more scope for doing things like fitting SuperSports, whereas the extended warranty is effectively an insurance policy, and the insurers can dictate and enforce whatever terms they like, regardless of whether they seem stupid or not. All of the above is from memory - a little bit of memory can be a dangerous thing - it might all be b  ks that I've misremembered  Gibbo205 said: UK law dictates one could fit none N-rated tyres to your car and Porsche could not deny a warranty claim unless they were able to prove the none N-rated tyres were the cause of the failure.

You like pushing the limits with Porsche don't you Gibbo  Safety wise you'd be fine, warranty wise - which way is the wind blowing? On a good day I'd imagine your OPC would tell you to change them in the event of a claim before they are obliged to send photos to Porsche, etc. Also what all2ofme said above applies. The standard manufacturers warranty that Porsche are obliged to provide is subject to Block Exemption and other rules, but the extended warranty is a contract between Porsche and buyer in which they can dictate whatever terms they want, however illogical or onerous they may be. Critically you choose whether to take out the extended warranty or not and therefore whether you abide by the terms, etc.

 Not sure why the OP has asked this question ? as in this thread (fifth post down) : http://www.pistonheads.com/xforums/topic.asp?h=0&a...He already appears to have all the answers to his question ? Perhaps the OP was bored on this Monday morning ? Either way, using the search facility and entering Pirelli & Michelin into the search box and searching in "title only" gave five pages of possible thread topics . . . .

i would of thought it would of been more of an issue for your insurance company rather than your Porsche Warranty?
i've got N rated Pilot Sports(not PS2) on my 18" winter wheels and there miles better than the P Zeros in the wet/damp/cool, in the warm & dry i don't notice much difference... when i change me rears i'll go P zeros but only because the fronts are so good... if i was changing all 4 i would go PS2

Nano2nd said: Rossos In that case I understand your comments. Basically Pirelli's lineup is as:- Corsa R - Dedicated track tyre Corsa System - 90% as good as Michelin CUP in dry, but 90% better in wet, awsome road tyre, though damn hard to source. Pzero - Flagship Pzero tyre, wins a lot of reviews. Pzero Rosso - Good tyre but with elements of comfort so not an all out handler. Pzero Nero - Avoid! So the Pzero is quite a bit better than the Rosso, compared to a PS2 though I don't know, I am guessing they are more or less on par as different reviews put them around equals.

I've stayed with the P-Zero's ever since buying her. I personally can't fault them at all, but then I've never tried anything else. My mate has his shod in Michelins which he rates highly but stated they do wear quickly. When we are out together in all types of weather I can't say there's any difference, but obviously driving style has a lot to do with that.

I am just going through this dilemma at the moment' can't get P zero N2 anywhere so might swap to Michelin PS2 or supersports in dialogue with dealer on the point as we speak.
