it's is about money and they buy 300,000 + sets a year so £200 a set cheaper is a number too big for me to know what it is lol
take a look at Ferrari the crapper cars have P zero's the higher up range have Michelin.
EVEY car is built to a price a when you buy 300,000 of any thing saving £200 per car adds up.

I have talked about Dunlops many times, all ring records run Cup 2 not dunlops, I had a set of Dunlops they cost more than cup2's in fact, I binned them after about 2k miles, hated them.
one does not have to track a car to see how crap P zero's are, I guess people get used to how a car drives with them and just accept it. but they really are sub standard tyres imo.
What's the chance of Michelin ever making MPS4S in both GT4 sizes?
They do but rears are not N0.
Afternoon, has anyone fitted Vredestein Ultrac Vortis on their Porsche?
I recently replaced my fronts on my 987.2 CS so have MPS2s all round but was considering the Vredesteins for when I next need a full set. I had a great experience with them on my old Audi S5.

I quite like the look of these, anyone tried them?

What’s the crack with n rated tyres? Is it a case of Porsche advise that they should be fitted necause the car has been setup using effective control tyres or is there any other reason. Hence is it ok/safe to use recognised performance tyre brands which meet the required speed ratings? Thanks Paul
N-rated tyres have been tested and approved by Porsche. They will always recommend them and if you have an extended warranty, they insist that they are fitted or will void the policy.
The issue is that Porsche do not regularly test new tyres on old models. So to maintain my warranty on my 987 CS I have to use their recommended tyres, which are all based on 10+ year old tyre technology.
Non-N tyres will be perfectly fine from premium brands and there are loads of reviews out there, but in my case I’m sticking with the recommended Michelin PS2s.

Below is the reply I received in 2017 from Michelin technical devision regarding my question on N - rated designations for Michelin tyres for the 718 Cayman S. Michelin start with "0" and each subsequent evolution is given a new number. N1, N2, etc.
Current Pirelli P-Zero N2 are long overdue for an update. They are not a proper fit on the optional wider 10.5" rims, they look over-stretched. Pirelli need to design a better tyre for Porsche Caymans and Boxsters.
Michelin are by a considerable margin the optimum tyre for all Porsche sports cars.

[font="times new roman,serif"][font="calibri,sans-serif"]N0 N1 are corresponding to the tyre design generation, Michelin is working with Porsche to design the tyre which offer the best level of performance and consumer satisfaction , also we identifify the different generation of tyre design by a number N1, N2…[/font][/font] [font="times new roman,serif"][font="calibri,sans-serif"]PS4S has been launched in January 2017. The PS4 S N0 which are homologated on your car are specifically design to optimize the performances of Cayman 718, and are the N numbers are purely sequential, they don’t offer any insight to the design of the tyres[/font][/font] [font="times new roman,serif"][font="calibri,sans-serif"] [/font][/font] [font="times new roman,serif"][font="calibri,sans-serif"] [/font][/font]

Sadly not true on many accounts
they test the cars on normal tyres most of the time, 911 etc can be seen on the MPSS launch tests but they never went N spec but won every test on 911's
Also Porsche don't test any N spec tyre on every car, so when you buy a N spec tyre for a 987 rear it's really from a front off a v10 C GT and should go no where near a Cayman !!
OPC and in fact no one gives a **** the tyre is for a v10 front CGT and not a rear Cayman Tyre !!
Porsche also will never test a new tyre on an old car, you telling me people with 964 run N spec tyres !
And last Porsche cannot void a warranty for not running N spec !, they can refuse to renew a warranty if the car does not pass a 111 point inspection which has N spec as one of the points.
seems a shame people have £50k cars but run 10 year old tyres designs, I never run N spec tyres bar Cup2's all my cars run PS4S which is todays class leading tyre, before all my cars ran MPSS.
I am not running shit tyres on £100k cars ! I binned my Dunlops and my P -zero as they are not upto the job.

David is making perfectly valid points on tyres.
Yes, you can get N - rated Michelin Cup 2s for example, for a 987 in 265 sizes but they have been originally designed as a front tyre. To be honest, I used 265 N-rated Cup 2's on the rear axle of my Cayman R, and non N-rated Cup 2 235's on the front. This worked perfectly well for me, and I achieved several podium finishes in competitive motorsport with just such a combination. There were no downsides at all.
It's important to remember that the Michelin PS2 is a 12 year old tyre. Construction and compound technology has evolved in leaps and bounds in twelve years. The PS4S uses dual compound technology in its asymmetric tread design and is the best current road tyre for Porsche sports cars, N-rated or not.

I agree with the spirit of what you are saying but have to respectfully disagree on some specifics. I agree that a Michelin PS4s is better than a PS2 in terms of materials used, design and overall abilities, and if I wasn't constrained by the Porsche Extended Warranty I would fit PS4s' without hesitation.
However...
Porsche do recommend specific tyres for specific vehicles, this can be referenced here: https://www.porsche.com/uk/accessoriesandservice/porscheservice/vehicleinformation/tyreapproval/
Every modern, and indeed Classic, Porsche has a tyre recommendation (mostly, I think, N-spec).
Porsche extended warranties are really quite restrictive and in the policy documentation they do require the car to have only approved parts fitted, this includes tyres. For those who choose to extend their warranty (the 3 year, from-new warranty has different conditions) they have to decide between the advantages of having it (for example I don't have the circa-£14000 it would cost to replace the PDK gearbox!) against the negatives (no mods, can only be serviced at Porsche etc).
So in summary, I would like to fit more modern tyres, as technology has advanced in the past 10 years, and I'd love for Porsche to approve and N-Spec PS4s' for the 987 CS, but fitting them without the 'N' would risk my warranty safety net.
Furthermore what we are actually talking about is a marginal change in tyre performance for daily driving, not a night and day change (in the specific case of PS2 vs PS4s), so its a comprise I'm willing to make.
I hope this all makes sense, and I totally appreciate views and priorities differ.
its a night and day change sorry to say, tyres have come on 10 fold.
as always it is a personal choice. no right and wrong what tyres people choose to buy.
But even safety in the wet if your other half drives it is massive from a PS2 to a PS4S. one might say a PS4S could save your life in extremes motorway crash or even a 50mph M40 drive in the wet !
but they won't refuse a warranty claim on an engine for a non N spec tyre fitted.
Porsche have to recommend a tyre as people, which can be seen on all makes of forum want to fit £50 tyres to 170mph cars, so I guess it's to protect the brand when people die in cars on tyres they don't recommend.
the issue is Porsche NEVER revisit older cars so you cannot buy a modern N rated tyre for a 987 car !

I bought PS2's in Feb 2018 and I'm more than happy with them for general and spirited driving.
They have been driven all year round, through the Beast from the East, right thro summer, in hot sun and cold rain and I haven't had any brown trouser moments.
They are an improvement over the Bridgestone RE050 that were on before (and were also on when I bought the car)
I went 'N' rated, and the price was ok.
Rim protection is very good on the N rated tyre too.
I'd probably look at PS4S next time, but in all fairness I have no reason to want to move away from the PS2's
