With which tyres are the Caymans being delivered? - Page 2 - Boxster/Cayman - PistonHeads UK

Hi all. Question spawned from another thread I created asking about different tyre types front and back due to the fronts on my Cayman needing replacing ( https://www.pistonheads.com/gassing/topic.asp?h=0&... ), and it made me wonder what tyres are the current 718 Caymans (and Boxsters I guess) being shipped with? I know there's a universal preference here for Michelins, but I wonder if Porsche is of the same opinion. Also keen to know if they're of the UUHP (MP4S / Eagle F1 SS) or UHP (MP4, Eagle F1 Asymmetrics, etc) variants? Thanks.

Picked up my GTS a few weeks ago and it came on PZeros.

Jefferson Steelflex said: Picked up my GTS a few weeks ago and it came on PZeros. Ok thanks. So another UHP level tyre then. The P Zeros are one of the few types available in both front and rear sizes too.

It's luck of the draw between P-Zero's and MPS4S I think. I'm not sure if any have been delivered with Eagle F1's. If you are replacing tyres I would choose the MPS4S.

Our GTS came with P-Zeros back in March. There was a 2022 Boxster parked opposite our house last week that had Eagle F1s but it was on the 19inch standard S wheels (although it was actually a 2.0 base).

Pirelli PZ$s for me on a GTS delivered in March however a chap was picking his GTS up the same day that was built the week before mine and it came with PS4Ss. Luck of the draw TBH. The PZ4s are pretty good IMO compared to the PS4Ss. Pirelli had to do something as the PS4Ss were wiping the floor with them.

I collected my 2016 C gts from a OPC in July. It was on 20 inch wheels and came with 4 brand new 'N' rated MP4's. I was a happy bunny.

My GTS 4.0 was built Sep 2022 and came on PZeros.

I've just had a brand new set of N1 P Zeros from someone whose C GTS was delivered beginning of December. They're going on my 981 C GTS replacing N0 P Zero's.

My GT4 built in May, arrived on Dunlop Sport Maxx Race 2's.

Thanks all. Those of you noting P Zero tyres, are they all PZ4s? Looking at this review , they would seem to be a very good tyre. Handy for me if I have to replace all 4, as they seem widely available. Edited by rawenghey on Wednesday 4th January 14:30

Yes. PZ4s

Delivered December on a 718 GTS.

PZ4s on CGTS - November 2022

Pirelli PZ4 is a very good tyre - low noise also. Should have quite a prominent protective sidewall profile.

I can't just make rash decisions, so if anyone is interested I have noted the scores of both the MPS4S and PZ4s in the 2021 Tyre Reviews test below: They aren't true rivals as the PZ4 competes with the MP4 in the UHP category, not the MPS4S in the UUHP category, but these are the tyres consistently available in Cayster sizes at the moment. As such, I expected the MPS4S to be better in the dry, but I didn't want something that fell off too badly in the wet as I do drive my car all year round. The number brackets next to each result is its position out of the 14 tyres on test. So, as expected I suppose. A UUHP tyre is empirically faster in the dry, but falls off a little in the wet. The UHP tyre is broadly excellent everywhere and in this instance the PZ4 would have beaten the MPS4S on aggregate, if it weren't for its oddly poor aquaplaning result. Not sure I'm any closer to an answer Got a few TDs booked this year, so will likely just go MPS4S.

You can’t look at a general tyre test and assume the Porsche fitted tyres will follow that trend. The Porsche tyres might have different tread compounds, construction, wear, grip, rolling resistance … etc

Pirellis consistently seem to receive a lot of criticism on here, yet in the magazine tests they always come out far closer. It’s almost as if some of these reviews were paid for… PZeros on Porsches have certainly been criticised quite a lot here in the past, whilst the Michelins and Goodyear feedback seems consistently far more favourable.

November 22 Arrived with Pirelli P-Zero PZ4's, I'd rather have the Michelins and I'm sure come replacement time I'll will swap to PS4S's.

It always amuses me when generalised conclusions are made about certain brands. Pirelli, for example, have a long standing reputation as an innovative manufacturer of quality performance tyres for a wide range of applications, they are the official supplier to F1 and many other race series, they are OE fitment on most prestige sports cars - Porsche, Ferrari, Mclaren, Lamborghini, etc, they come out well in most independent reviews……… But, it just takes a few people on an internet forum to declare that Pirelli’s are rubbish and that somehow has more substance - it’s brilliant

I just trust my own experiences having read so much utter horses t. To answer the OPs question, and a few years back now but my 718 was delivered on P Zero N1s. They were fine in the dry but in the wet I didn’t get on with them at all. Changing to Goodyears as I couldn’t get Michelins in 18”s was a revelation, grip in the wet was night and day improved whilst also being slightly quieter on the motorway (not that it is a particularly quiet car). Make of that what you will!

If you're just relying on unqualified subjective opinions of people on the Internet... Meh, I'll just leave that one hang. It seems reasonable that in the absence of actual data from Porsche on how the the OEM tyres are modified, then using "generic" tyre tests is the best guide we have available. MPS4S score very well in lots of tests, as does its more comfort-oriented MP4, but the "light and day" narrative of Michelins vs any other manufacturer is clearly not true.

See the seats debacle on the Emira thread. Nobody had mentioned it across tons of reviews.

I personally think they were just looking for an excuse to get out though, clearly some “circumstances changed” orders.

Tyre Reviews on YouTube covered this, it's an interesting watch and covers the Michelin PS4s in regular format and BMW Spec. https://www.youtube.com/watch?v=COA630Juf_U In short. Different compounds, different construction, modified tread pattern/depths. Edited by M11rph on Sunday 8th January 08:27

I have been a tyre engineer at both tyre companies and car companies. It’s not unusual for tyre compounds and construction to change… therefore the generic tyre tests might not be that relevant. The other important aspect of tyre tests is that they test some aspects of tyre performance that many customers will never use, for example absolute speed around a dry or wet lap. The more subjective aspects of feel and precision are often not explored in much depth, though both of those are probably more relevant to the average customer (myself included).

I've had a set of P Zero SC N1 on my 981 GT4 for a few years now for road use. I swap over to set of Michelin Cup 2 for track days, and they are great as long as I remember to keep letting enough air out. Don't like getting too warm! However if a track day looks like it's bound to be wet at any point in future, the Pirellis will go straight back on. They are so much more predictable, and I think ultimately will be quicker too, set at the right pressures for the conditions. A lot of people seem very tied to brands, when actually the best tyre for the job will depend more on intended purpose by design than the manufacturer. My 981 GT4 came with Dunlop Sport Maxx Race tyres. While I am sure they were great on track, I couldn't wait to change them for road use. Swapping to set of tyres more focused on road use was a transformation for everyday ride, handling and wet weather performance. Liam

My Cayman GTS 4.0 was built Nov/Dec 22, took delivery last week and it came with MPS4S's which I was pleased about. My previous 981 GTS had Pirelli's which I then swapped to Eagle F1's. Not sure I'm even qualified/experienced enough to tell the difference, but there does seem to be alot of praise for the Michelin's.
