Clubsport S Cup 2 tyres - bespoke?

[scanesare]

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.
