Discussion
I have just spent hours trawling through old threads on all matters relating to tyres..... feel a headache coming on!
Now I know they are not 'N' rated but from all the reviews I have read and the tests conducted WITH Porsche and specific reviews with a 997 Carrera S wearing the Michelin Super Sport tyres I am confident that the car will not blow up or slide off the road like it's on ice if I put them on.
My car is not under an OPC warranty and the guys I bought my car from say the warranty would not be affected in any way shape or form if I put non N rated tyres on.
So I ordered some
Just got an email back from the supplier which said.....
Thank you for your order.
Before we process your order this email is to inform you that your chosen tyres are not Porsche approved.
Please can you confirm that you are happy for us to proceed.
With thanks & kind regards

Now I am worried again, should I? Shouldn't I? Arrrrgh!
It's like my dad used to say "Well........it's up to you son but don't say I didn't warn you"

Well, it's up to you, but...
Personally if I was out of warranty I would go for it. I'm in warranty, and wish to stay that way, thus I'm going for PS2s.
Somebody has said that an N-rating will be forthcoming - is your need that urgent?
I need them now as I am booked on the Petrolhead Nirvana Alpine tour and the fronts are very low (rears are semi-OK and will be going on ebay) Personally if I was out of warranty I would go for it. I'm in warranty, and wish to stay that way, thus I'm going for PS2s.

I have replied to the supplier telling them to go ahead and order the tyres.........i'll be fine....... I think
I've never seen or read the terms of the Porsche Warranty (and I don't have a Porsche or a Porsche Warranty....), but which one of the below statements is correct?
1) if you equip your car with any non-Porsche approved/OEM item then the warranty is VOID. Full stop. Do not pass go. You have no warranty any more. At all.
OR
2) if you equip your car with any non-Porsche approved/OEM item then the OPC may at some point (if it chooses) decide that your warranty is void and thereafter, your warranty is VOID. Full stop. Do not pass go. You have no warranty any more. At all.
OR
3) if you equip your car with any non-Porsche approved/OEM item, and it can be proved that doing so caused or contributed to the failure for which you are then attempting to make a claim under the warranty, the OPC can refuse to pay out in respect of that part of the claim, but your warranty is still valid and would be paid out on all other issues not caused by the non-Porsche approved/OEM item
If it's number 3), and if the main issues to be scared about re the warranty is having the safety net if the engine or gearbox goes bang, would it be fairly difficult in that scenario for an OPC to claim that either occurence was as a result of tyre choice?

Make sure you have your car thouroughly checked, new brake pads and fresh oil in your engine before you go too - if it's anything like the PN tour I went on in '09, (Massif Central/Millau Bridge/Mont Ventoux) your car will take one hell of a beating. The electrical and mechanical repairs to my then 997S.1 cost £1500 when I got back! Wouldn't have missed it for the world....@ Chunk - I'd love to answer that, but I've not seen the wording (yes, I know, given my profession I should probably read it). My feeling is that it's option 3, but I'm not at all certain. I can't see, as you say, how they could possibly refuse a claim for a knackered CD player if you're running the 'wrong' tyres. I stand to be corrected though - is the wording online? I've looked and never found...

As far as I understand it the Porsche extended warranty is underwritten by a 3rd party provider. It simply stipulates Porsche Approved parts only or the warranty (as a whole) is invalid. And yes, they can do this as it's a 3rd party warranty, not a manufacturer warranty.1) if you equip your car with any non-Porsche approved/OEM item then the warranty is VOID. Full stop.

Thanks IanThe car will be serviced before I go and it's got new discs and pads all round. The plan now is to get the tyres on and then have a full geo check. Cant wait for the trip!

Just got this email back from the supplier...

Officially, Porsche won’t like it. The downside to fitting a non Porsche approved tyre could come when you wish to part exchange at a Porsche dealer. If they spot it, they may reduce the value of your car.
We are unaware of any detrimental effects of fitting the Super Sport, & as Michelin’s latest development, they should show an improvement in performance.
Currently, the front’s in the Super Sport are not available until the 07/06. The rear fitment are available.
The Porsche approved Pilot Sport N2 is available in both sizes.
A further question, our technical info indicates that the front fitment, should have a load & speed rating of 87Y, as opposed to the 91Y on the order. Please confirm the current rating.
Sorry to make this hard work, but, with such a high performance car, we need to make sure we get it right.
I didn't think about the load rating.....Hmmm maybe it's best to just go for the PS2'sWe are unaware of any detrimental effects of fitting the Super Sport, & as Michelin’s latest development, they should show an improvement in performance.

I know! 2500 odd miles on varying surfaces in (hopefully) hot weather......should give them a good workout 

Mind you I was young and foolish, my driving style has moderated
A little bit

I've been running non N-rated winter tyres for the last 2 years between about November and March and am still here to tell the story. What's more, they have got significantly less grip in warm conditions than MPSS will ever have. You may want to run it by your insurance company for peace of mind as I have, but otherwise its the logical choice.

Why is there such a problem fitting N rated tyres. Do they not come in the type you want?When I replaced mine last, the difference in price between N4 rated and non N rated was about £12 for the set of four.
Ok it was 968CS, but I'm syre the rears for my 993 were not alot different in price. £5 maybe.
