General, Sumitomo, Continental. toyo, Pirelli, Yokohama, Michelin seem to be the only ones in limited versions.

A 285/35 is almost a full inch larger in overall diameter. 295/30-18 is around 25" flat. 285/35-18 is 25.9".

You wan to run a 285/30 not 35.

For anybody reading. Note there is mention of PS4 and 4S here. 4S is the ultra performance tire, the main one everybody raves about for street use. PS4 is an all Season Performance Sport tire and not as capable.

Just re-discovering this thread and appreciate SToronto clarification. I thought 4S was a pluralization had no idea these were different products ....glad I ordered the right one last night!

Except that he's wrong. PS4 is not an all-season tire. PS4s is the later iteration of PS4, both are summer tires. PS5 is out now.

There is also a "Pilot Sport All-Season 4", which is a different tire and probably the cause of his confusion.

Michelin have collaboraed together with Porsche to make a tire for their cars over the years. Tires that is ‘N’ marked is therefore produced for Porsche models, standards and specifications.
The N standards main goal is to quality secure the customer that the tire is within the manufactur requirements.
These requirements consist of tire compund, stiffer sidewall, wear and I belive tire noise.

On some tires the ‘N’ is followed by a number. Like my Michelin PS2’s produced in 2022, they are marked with ‘PS2 N3’.
The number means its the version / iteration number 3 of that model tire since its launch.
Within 2024 I have seen the PS2 N4 variant available for purchase.

When I bought PS2’s in 2018, they were marked with ‘N2’. And when they were launched, they had only the N marking without a number (or so Ive heard).

So to anwser your question; Yes, the Michelin PS2’s tire model is updated throughout the years. By verifying the number following the `N` you can identify what verison of the tire it is. And by the looks of it, they have kept the thread pattern of the original model and I would guess updated the tire compound to the better.

The stiffer sidewalls is one of those requirements that does it for me. Ive tried relativly similar 993 c2`s with diffrent tires, but same size, where the load bearing or flex resistance during cornering, it was suprisingly how big the diffrence was. One 993 were on Ps2`s and I dont remember what the other 993 had, but the difference was very noticeable. (Both 993s were set up with pss10 suspension and similar in height/stiffness).

Im currently on my tird set of PS2’s on my 993, but thats because those tires deliver more than enough for my set of driving skills

Note that Pirelli and probably others aswell have `N` marked tires in their selection.

my 2 cents: I have tried (on my own 993) PS2 N2, Cup 2 Connect, Continental Extremecontact02. The PS2 is not in the same league in any way shape or form. It is old tech and you can feel it.

Cup 2 is the absolute best, but it was out of stock all across europe when I wore them out last year, so I switched to the extremecontact02 which are really really good.

But obviously my sample size is limited, so I also asked my suspension guy (famous guy in the UK that primarily deals with porsches). He liked my continentals the most for a 993, putting it slightly better than a PS4S. Agreed that PS2 are not in the same league. And he's not a fan of Cup2 for street use, especially in a wet UK.

Famous guy in UK....Tuthill? If so, huge fan of him

Since I last posted I have installed MPS4s's on my turbo in 245/295 sizes. A better OE match than what was available before in 235/285 sizes. I have to say I knew it from other cars like my Boxster GTS that the MPS4s is a superior tire to the SS and PS2 but the improvement over the PS2 was mind blowing. At one time I liked the PS2 but I can no longer drive them they are so lacking compared to the modern tires made today. I could not get the 17" sizes I needed for my 928GTS. I was running PS2's so I switched to the continental Contact extreme DWS 06 all season and surprisingly it too was a superior tire to the PS2 in every respect irrespective of it being all season vs summer. One of the best in the wet. On that car there is no need for the summer tire and the Conti has proven to be a great all around tire. I have had the new 220 tread wear Cup2's on track on my 964 and on my GT4 and I will not be replacing them. They are just adequate and not much better than the MPS4s's but will hold up slightly better on track. Still horrible in the rain and a bit noisy. For non race tire on track I have been using the RE71RS's. One of the more impressive tires I have driven on lately. Just acceptable in the wet but amazing grip in the dry with very nice even tread wear, long lasting and far more affordable.

Tire technology is improving exponentially and some of what Porsche recommends I wouldn't touch. Some of the tires my new cars have been delivered with I change out ASAP they just suck for the car and don't understand why they are on Porsche's approved list.

I only use N rated tires on my 993. So PS2 N4 I think is the current generation.

nile13

I would say tat there are (significantly better and cheaper at the same time) tires for a 993 today. Do you really think that Michelin tests anything with a 993 or any old Porsche?

fatmike

The 993 exposes the soft sidewall on the 4S. It feels “squishy”. Ultimately I have no doubt it’s a superior tire, but it has a different feel.

Maybe that feel is OK for you. Maybe not. I prefer the PS2’s stiffer sidewall on the 993.

I’m very happy with the 4S on the Cayman.

nk993

not only do they not test with a 993, the N rating higher than N2 is not applicable at all to a 993 if one wants to nitpick. N2 is the last n rated tire for a 993 and is extremely old tech. It’s silly using it

cobalt

I don't know why everyone falls for the N rating BS. The PS2 sidewall isn't much stiffer than any of the other Michelin's. If you want a stiff sidewall go Pirelli. The different tires and N rating primarily changes the rubber compound across the tire contact patch and has little to do with sidewall stiffness or overall tire construction. You should be running 36/44 PSI cold if running 18" staggered if not that could be your issue. The tire will get squirmy if you run lower pressures that is on the street of course.
