I need to get a new rear tyre due to a puncture, and reading quite a few of the press releases from when the car came out, they all mention that the car is shod with bespoke Cup 2 tyres from Michelin.
Does anyone know if this is correct, or whether a standard Cup 2 tyre will do?
I have contacted Michelin UK, as VW don't even have the tyres available as a spare part - just said they can't help me..

I have read most stuff relating to the CSS but not heard of bespoke to CSS tires before, any links to confirm this? I'm 99% sure it's the standard PSC2.
If I had to change tires on the CSS I would seriously consider the new Michelin Pilot Sport 4S which seems an excellent performer. Better than the old MPSS so closer to the PSC2 but with big improvements on the wet, economy and noise areas. The PSC2 does not make much sense on any car that is not tracked often or at least enjoy very good, dry tarmac on a regular basis, I'd imagine it's even worse on the average UK roads + weather combo.

Here's one article mentioning bespoke Cup 2's:
http://www.evo.co.uk/volkswagen/golf-gti-clubsport/17816/volkswagen-golf-gti-clubsport-s-review-updated-with-uk-driving (http://www.evo.co.uk/volkswagen/golf-gti-clubsport/17816/volkswagen-golf-gti-clubsport-s-review-updated-with-uk-driving)
I wonder if it's just marketing bs..

There was a hell of a lot of marketing bs surrounding the Clubsports in both guises. I'm sure there would have been a note of some sort within the car literature that you get if the tyres were bespoke but the easiest thing to do is check the exact writing on the tyre sidewall. Just like Porsches with their N spec (which the CS might have borrowed) if there is something bespoke about them then the tyres will tell you in code.

If you have a big monitor you might be able to read what it says on mine.

Not marketing BS, this is only an online article of a car magazine (not related to VW) and while EVO are pretty respectable in general, their online articles often suffer from too much post-upload editing and confusing info. I have noticed they change articles but adding pieces of text after a while only to make them appear more recent. That "bespoke" mention is something that has probably slipped there. Other than I have never heard about Clubsport bespoke tires, in the hot-hatch group test between CSS, Cupra, Focus RS and Type-R in magazine form which is much more looked after for typos and accuracy (EVO 227) I read:
"...to level the playing field all four cars wear the same rubber. The MPSC2 is standard-fit on the CSS and an optional extra on both the Focus RS and Cupra 290 but we've had to fit them ourselves to the Type R...". They would have mentioned of a bespoke tire there unless the Focus is also coming with bespoke to CSS tires as an option, probably not.

I have received confirmation from Michelin:
None of our MICHELIN Sport Cup2 tyres are homologated specifically for VW vehicles.
So it looks like a standard replacement will do.
-
My experience of SC2s were when i had a puncture, whilst the puncture was repairable in the 300m or so to a come to a halt the side wall was toast
I have been amazed how reliant these were to abuse on track and how well they cleaned up
-
I think they are great but only if you either don't use the car in cold conditions or use winter wheels.

Wht pressure does everyone run in the cup2?
Door sticker says 38 which is crazy
Michelin replied to me and said follow manufacturer guide on road but on track 34psi
I currently have them at 34 front and rear cold and feels ok

I imagine most will stick to manufacturer's recommendations which are there for a reason unless having the expertise to do their own load/strength calculations that I assume you must have?
34 for the track makes sense as they will quickly rise anywhere from 37 to 40 after a couple of laps, but why would you want to run that pressure on the road? Tyres have a wide safe operation range so it's no surprise they feel "ok", however it doesn't sound optimal at all.

Cup 2's are supposed to run softer than normal tyres.
For what it's worth I ran mine at 32psi

Were those MPSC2 19"? Regardless, if Michelin recommend 34 for the track, I can only imagine road pressures being higher than that, not lower.

Yes and the size was 235/35/19 so exact same size.

34 for the track is HOT so that’s lower than 38 cold VW recommend
If they advise 38 for a concrete Bridgestone then it can’t be the same for a Michelin it’s a totally different tyre.
I would say 32 sounds about right as they’re reinforced side walls. 38 is mental
My wife’s mini runs 31psi or something and that’s on Michelin energy so why vw reckon 38 is optimal is purely for fuel efficiency
-
Also why would it need the same tyre pressure as a golf R which is 200kg heavier?
It’s got to be for fuel economy and to try and prevent the rims getting damaged by pot holes surely.

As I said a few weeks ago when people mentioned about the recommend pressures changing to 38psi I still think it has to do with VW's attempt to get the emissions closer to the joke that they were.

I saw on another mk7 site that it was the same tyre as used by Porsche, but a different load rating...

Porsche use N rated ones but there is no difference in them.

Porsches N rated tyres go through a very expensive homlogation process with the tyre manufacturer with the tyre being custom developed to suit the spec demanded by vehicle manufacturer.
VW chose an N rated tyre which is a Porsche fitment, this is probably not unrelated to the fact that the chassis development team leader used to work for Porsche and therefore knew exactly how an N rated Cup 2 tyre would benefit the Clubsport S compared to a non-N rated version - for example a slightly stiffer sidewall.
So if you are replacing Cup 2s, especially not as a full set, I'd always get the N rated version.

I think the first question is probably does the OP stlll have the car given it was 2017 when he asked the question! :grin:
'N' rated is a Porsche approval confirming that the tyre was tested and approved at the Nurburgring hence the 'N'. Makes sense that Schebsdat would use it given where they were going for the record and his work on the 997 RS.
Marketing teams love hyping it all up at launch. My favourite is the ambiguity they like to create with 'limited production' and 'limited edition'. This gets shorthanded to 'limited' invariably.

Run mine at 35.5 cold, 38 feels way to high.

I know, right? Better yet is when you get the 'flat earth argument' on a forum with two guys (it's always dudes) arguing over technical details where the physics simply wouldn't apply. If you have a McMurtry, then you get a pass. :grin:
