PS2 or PS4 tyres for 993 (17")?

Hi all. I'm new here.

On my 993, I'm changing my 18" TT wheels for 17" Cup2, but I don't know what tyres I should use. Some kind of Michelin for sure - but should I go for the Porsche-approved and N-rated PS2 or would the PS4 be better? Road use only. I use the car for my daily drive to work at 6am all year round.

There seem to be 500 billion threads on 18" tyres but nothing on 17".
Thoughts?

Thanks in advance.

Yep. Same sizes. I wondered whether PS4 is an update of the n-rated PS2.

Thanks folks. I think 17” is the limiting factor for the sportier tyres.
No one has suggested that PS4 are better than PS2 so I’m going for the N-rated PS2. About £550 fitted seems OK to me.

(I only wish the HVAC was so simple to resolve)
