Sidewalls on the PS4S are very soft.

An interesting thread here comparing the PS2 N4 and the PS4S.

This says to me he preferred PS2 N4 in 18 inch over PS4S in 19 inch. If you ignore looks most people prefer going down in wheel size. Especially on rubbish roads like in the states.

[ajondyh]

I have PS4S fitted on my R. I have also had PS2's and imho the 4S are head and shoulders above the 2S in wet and dry, hot and cold conditions. Undoubtedly the best road legal tyre I've tried.

I don't think you can compare a cup2 with a road tyre. A cup2 is basically a track day tyre with some road manners. If you have never tried a track day type slick [semi slick Road legal] tyre on a road car I recommend you do it. I did by accident. I bought some OZ wheels for my BMW. The seller had been using them with r888 tyres for track. They had only seen a few laps and the wheels were almost new. Only one of the front tyres had some wear. I put them on my car just to try it. They were amazing - in the dry. Unbelievable amounts of grip. I would laugh out loud at the g forces. I would go round and round any round about just for fun. It was intoxicating. As soon as the slightest spots of rain appeared the party was over. They were a bit noisy too. And that was just a medium warm BMW. On a Porsche they would be next level grippy.

Interesting I need to replace all 4 on my 987 Spyder 19" have at present MPS2 N rated as the car no longer under any warranty don't need to stick with Porsche approved, thought I would replace with MPS4S non N rated ..so should I stick or change don't use car often tyres have 4ml no cracks splits never mended but now 10yr old ...some say still use them ?

Noticed on that BMW link the approved ones are only B wet rated and the non approved A rated one would think the other way round

Who was looking for a blue R?
New listing today, manual, but no buckets, super low miles.

https://www.autotrader.co.uk/car-details/202302104...

Pics of it now on the listing. It’s nice but lacking AC and the wrong wheels (in my opinion). Could be a tough sale.

[Old Trout]

It's a lot of money for the wrong wheels and no buckets, even with the low mileage.

[Edmundo2]

Yep..looks in good nick but can't see it going quickly in that spec at that price..

I have PS4S all round on my R, and they are a great tyre for a combination of all round wet and dry grip, road noise, ride comfort and durability.
I have also read that they may not be quite a sporty in terms of steering response or track performance as the previous MPSS but are supposed to have a wider operating range.

The PS4S is actually quite an old tyre now, having come out in around 2017. Worth watching this review comparing all the latest UHP tyres. The Goodyear Eagle F1 Supersport and Conti Sport Contact 7 were both released in 2022 and may have moved the game on until the new PS5S is released.

Couldn't agree more, and would add that "track day" tyres need temperature as well as wet roads before they even work as well as the average sporty road tyre. I'm told most start to develop grip from 35-40 degrees C, which means even on cold roads in the UK autumn/winter/spring they aren't great unless you've just been hooning around big roundabouts or good fast roads to get some heat into them. On greasy roads, and in full wet, Cup 2s are truly awful. They tend to "tram-line" and get disturbed by poor surfaces a bit too.

I have my Cup 2s on a spare set of rims so I can run around on road tyres when the conditions and occasion aren't conducive to track day tyres. That turns out to be quite a lot of the time. (981 GT4 rather than Cayman R, but will be very similar for both.)

Agreed, Continental SC7 would be my choice today if going non N-rated.

Had Contis on my FK8 Civic Type-R, great tyre. Swapped to Michelins due to internet hype, then swapped back again.

I recently fitted premium contact 6 to my 981 and they're great. Went on a run with some other Boxsters. The lead car was a 987 Boxster and he also had premium contact 6 in the same sizes as Cayman R. He also said he really likes them too. During this run I had been following behind him. After he commented that he was impressed I kept up with him as everyone else had fell away. I am not normally a quick driver so I was surprised by this and put it down to the new tyres. That's why we got to talking about tyres and he told me he also had them etc. Not very scientific I know but still. I'm now also thinking about moving away from Michelin and towards Continental when any of my cars need new boots. The premium contact isn't even their sports tyre but it's great.

Conversely I had Premium Contact 6’s on my 964 and couldn’t get on with them in a way I’ve never been able to explain

Its very much whats good for the goose isnt good for the gander


I had PS4S's on my M5 - loved them
I have them on my 987 Spyder - love them
I have them on my 993 - hate them... I dont know if its the size and the weight ( or lack of weight ) on the front of the 993 but they just done seem to work.

[Edmundo2]

I guess it very much depends on your planned use but my old S was a weekend toy and was set up with KW's, LSD, as loud as possible etc...

I only used it for driving as quickly as was sensible on public roads and as such it really only went out in the dry..As mentioned the MPSS seemed great with the MPS4S not quite as good..

Its probably fair to say that it would have been the other way around in the wet but on the basis it wasn't being used in these conditions I should probably have gone for Cup 2's and just acknowledged they would be sketchy if I happened to find myself out in greasy conditions and therefore backed off accordingly ..

I ran my Caterham on Toyo R888 which are track focused and tbh they were great when driving in typical blatting conditions, ie summer evenings and weekends..

I'm currently on the hunt for an Evora 400, ( or poss Cayman R ), and whilst they are designed to be practical enough for daily use I need to remind myself that I will be using it as a weekend toy so therefore don't need a practical tyre but rather something that makes spirited driving as good as it can be in warm dry conditions so poss need to look beyond the highly rated "all rounder" reputation of MPS4S

Some interesting tyre chat. I started off with a few sets of PS2 on my R and was always pretty happy with them. I fitted them as I had extended warranty. When I ditched the warranty I was going to fit PS4S however that summer Michelin Europe ran out of 265/35/19 PS4S for several months so I fitted PSS. At first I really liked them, however as they wore (the rears seem to wear faster than the PS2s did), the wet grip really suffered. I've still got them on the car but don't drive it in the wet. It just isn't enjoyable. I find the rear grip in the wet is weirdly inconsistent and I just cant get any confidence in the car. It also has a habit of gripping at the front then getting very twitchy at the rear - perhaps fun if you've got the skills for that, but on the road I like the car to be more planted. On the PS2 I had no such issues. Indeed I've a pic of the car sat with steam coming off all 4 tyres after stopping following a very spirited bit of wet weather driving on a very fun and challenging road.

I've also borrowed a set of rims with Cup 2s to try on the car. In the dry they are by some margin the most fun to drive the car on. You can really lean on it. I also drove with them on in some pretty epic rain. You definitely want to avoid standing water, but the car never surprised me in any way. Grip was low but break away was progressive and it wasn't snappy - the PSS can be in similar conditions.

I'm torn on what to fit next. It definitely wont be PSS again though.

Interesting chat on tyres.

My R lives on Cup2s all year round both road and track. Personally find them decent in the dry and good enough in the wet. They only turn to ste once the ambient temps get below 5°c and then you struggle to get them working on the road. They’re a reasonably capable track”ish tyre but far from a proper track tyre imo.

I daily drive my Clio March-October on R888Rs and they’re a noisy bloody thing, but they are superb to drive on and work surprising well in the wet too. They lack comfort though and come winter time, I’m happy and relieved to swap on to Michelin PS3s for the cold, wet and yukky stuff. What they do offer though is brilliant feel and feedback. No normal UHP tyre feels quite like a 888, they're just brilliant fun.

As someone said previously, it’s all about the turn in and steering feel for me. Everything less than a Cup 2 on the Cayman makes the front axle feel a bit gooey and I don’t like it, not that it makes anything else a bad tyre, you just get used to how your car feels and knowing it drives a certain way. For me, that means my R will only ever be on a Cup2 till they make something better.



Cup 2s are decent, but still far from a proper track tyre imo.
Go try some Direzzas, Kumho V70as or even a cheap AR1 if you want something really fun.

This was a set of V70As that were almost new before a trip around the NC500. This was how they looked once I arrived back in Essex… oops.
Still never driven on anything with more grip that’s road legal.

Ok it sounds like I may have misjudged the cup 2 tyres. I have never had any or driven a car wearing them. From what you're saying they may have more road manners than a full on road legal track type tyre like the r888.

I will agree that the grip is infectious. I loved the r888 on a road car. It never felt the same again. Everything else felt like mush afterwards.

[Escy]

I'm running Yokohama AD08R on my Boxster (which is >500bhp) they are track day tyres that need heat in them to perform properly. I rarely use the car in the wet or through the winter, if I do, I just don't put my foot down as it's the wrong tyre for the job. I'm impressed with how well I can put the power down when they are up to working temperature on a decent day.

987, now a classic
