What tyres would people recommend for a 997.2 GT3?

Currently on Cups but looking to change if there is a better all round option - what about these new pilot sports 2's on the new 991 GT3?

..Michelin PS2's take some beating in my experience..!
Depends on what you want to do with it, but consider winter options too if it's a daily, defo park the cups for a while.. wink

I don't think the new Pilot Cup 2's are widely available yet, are they?

Michelin Supersports would be the obvious alternative (rather than PS2) assuming you don't need the N-rating??

Thanks guys - don't need N rating? What is that?

The cups are great because there isn't much grip, but ideally I'd like a smidge more as at the moment I'm having to be a bit wary. I don't want too much grip either mind! I do want it moving around and I like the wet greasy conditions as it's easier to get the car sliding, the thing with the cups is they mean you have to pay attention all the time

In which case i'd suggest Michelin Pilot Super Sports...available in RS sizes..so assume they'd be avail in GT3.

Got a view on them? Did you manage to get the exact size?

I have the exact same size and load rating MPSS tyres as the N rated Corsas previously fitted.

MPSS does not feel as grippy as the Corsas in the dry and warm. In the wet/damp, MPSS is more confidence inspiring as it feels more planted, and is much less susceptible to the car suddenly going light over puddles, wet leaves and damp patches. MPSS, for me, makes the GT3 much more usable in winter.

There is no discernible difference (at least not to me in my driving (road, with ocassional track day)) between MPSS and Corsa with regard to suspension compliance and steering feel. On reflection, steering feel on Corsas is slightly more committed -- the car feels slightly more eager to turn in and you can get more speed into, around and out of a corner.

MPSS is as noisy as Corsa.

IMHO, MPSS is fine, but it is a compromise.

Is that Pirelli P Zeros? What is N rating? Is it 'safety' related

Thanks for sharing

Yes, it's PZero Corsas. N rating is Porsche approved; surely you know about that?

N-rated tyres required for Porsche warranty.

Theoretically, but I run MPSS and my dealer is absolutely fine with warranty work that is unrelated to tyres ( There have been 2 issues in the last 6 months)

The N Rated tag is completely out of date on a 6 year old car, Super Sports are not N Rated but the older (And still excellent) PS2s are N Rated.

Personally I think Cups are borderline dangerous and should not be fitted without all sorts of warnings. They start new with 5mm of tread, are softer and although just about capable of clearing standing water when new, they are positively lethal in heavy rain when worn near the legal limit (3000 miles in my case on the rears running slightly altered and very common geo from JZM ) I have never been as scared as when driving a 997 GT3 through Germany on a very wet autoroute with the car aquaplaning in a straight line at 40 mph.
Cups are IMHO a vanity tyre to fit for any owner. Unless you really want the best possible track performance (And I'd look at cheaper tyres for that sort of thing anyway) the extra grip on the road is negligible compared to the compromises they require of you and the , outrageous, cost of them.
Corsas are much better if you really want a track based semi-slick option.

I have had warranty work (new battery, and new ignition barrell) done on my GT3 with MPSS no problems, MPSS not even mentioned.

As in sure you are aware, your dealer is not able to vary the terms of the approved warranty - it is an insurance policy.

That means that while you may get away with minor warranty claims, a major claim might be investigated in much more detail and the failure to comply with the terms of the policy (ie non N-rated tyres) could lead to the claim being thrown out.

Having said that you would hope that common sense would prevail if the tyres are clearly unrelated to the claim! It is a risk that you run though, so you should be aware of that..!

Yes, you are not wrong BUT in reality, the fact is it is legally ambiguous whether the Warranty is invalidated by a variation that is unrelated to the claim AND, in the real world your Porsche Dealer is not remotely interested in whether the legal and correct size (And very good) tyres fitted are not N Rated or not.
They fixed my car twice without a murmur of complaint as they have done for other posters on this thread.In conversations with the Service personnel the tyre issue was shrugged off as irrelevant.

But absolutely right on the Warranty issue.

Unless you can have first hand experience of such a case, this is conjecture and nothing more. I'm yet to hear of such a case and have owned many 911s all in warranty. I have run MPSS on both my 7.2 GT3s and have even had a warranty renewed shod with them. In RS 325 cross section size, the MPSS doesn't fit any other car so go figure; and is now standard tyre for CGT and was standard equipment for most 200mph super cars. It is a safer tyre in UK driving and cross continent bashing and only loses out marginally on track but with 5-6x life. It's a no brainer and legally wouldn't stand up. Cup2s, as I've said in previous posts on this perennial subject, have a tread depth more akin to MPSS so will clear water and now have a longer wear life than Cup+. I'm hoping they make them in 7.2 sizes...my source at Michelin says they will be but no date yet. When they do I will put these on instead of MPSS. Oh, and I run MPSS on my other family car.

My back-pocket solution...always on hand if my or any OPC chooses to be silly is to have a spare set of cups (barely legal, but legal) that can be put back on if required. A real ball-ache to do, but the option is there if they want to do that for duration of any warranty or renewal work. So far all have declined to do this or thought it necessary.

If you find them in your size, consider Yoko Advan Neova AD08 (although mine is a 996). I was surprised to find them sticky enough for occasional summer track use with a relatively stiff sidewall (though Cups are better), sufficient tread and pattern to cope with floods of standing water at Goodwood, and just about enough progressive breakaway for greasy conditions, though as always a sensitive right foot is a must.

What I'm stating is 100% factual:
1) Individual dealers are not authorised to change the terms of the Approved used warranty.
2) The terms of the warranty require N-rated tyres to be fitted

Surely you are not disputing that?

I've quite clearly stated that this is unlikely to be an issue for small claims and may only be a potential issue for later ones.

There is a risk that you might not be covered - the size of this risk is for the individual to determine!

Seriously begin to wonder whether this is not borderline paranoia...or scare mongering....

no offence intended - and could understand if some taken - but really?

In the real world, as opposed to that occupied by lawyers....I struggle to see that Porsche would alienate a customer on this basis....but hey...on this side of the pond maybe customer service is still a novel concept.
