Cup 2 Star Specs

Bon F80 · 09-14-2019, 12:01 PM

hi, may I know pls anyone can confirm the Michelin part numbers of the Cup 2 Star specs originally equipped for M4 GTS?

I've contacted a few Michelin dealers they told me that there are a few versions for the same Cup 2 tire sizes (F: 265/35-19, R: 285/30-20) so they
are not certain which ones are originally equiped for my M4 GTS.

on Tirerack.com, the part numbers are not listed.
- F: https://www.tirerack.com/tires/tires...635YR9PSC2XLV4
- R: https://www.tirerack.com/tires/tires...=83YR0PSC2XLV2

are these the correct Michelin part numbers?

- F: 24523
- R: 35654

If the Cup 2 285/30 R20 has a star on it, it fits.

There are 2 Cup 2 tires fitting 265/35 R19: the rear tire for E90 M3 and M2 (DT*) and the front one for our cars (just *). The optional PSS are only 255/35 R19.

BMW Part numbers:
DT* = 85452593828
* = 85452593787

Here in Europe you can also tell them apart by looking at a label with ratings (from A to G, good to worse) for fuel consumption and wet traction. The DT* is rated E/C and the * is E/E.

What tire pressure would you use on this setup?

Is this the same for the M3 CS? I'm having 763Ms with PSC2s installed this week on my ZCP F80

Sorry, I don't have access to an M3cs owner's manual. Maybe some non-USA M3cs owners can chime in...

32 psi.

I just got everything mounted, balanced and installed today and will be posting a review soon, but I can now see why people say the CS behaves differently. This CS style wheel setup is amazing with the Cup 2s.
