Michelin Pilot Sport Cup2 - Upgrade on Stock 19" 437m Wheels

[MAC 1977]

My car is 2015 M3 on Stock 19" 437m wheels with 10mm spacers front and rear and lowered on MP HAS.

I've decided to go with the Michelin Pilot Sport Cup2 tires as an upgrade. I need a bit of help mainly with the front tires. Which one to choose.

265/35 19 up front (5 choices on the tire rack website):

265/35ZR19 (98Y) XL Star BMW M2 - Tread Width 9.5"
265/35ZR19 (98Y) XL MO Mercedes - Tread Width 9.5"
265/35ZR19 (98Y) XL MO1 Mercedes - Tread Width 9.5"
265/35ZR19 (98Y) XL - Tread Width 9.2"
265/35ZR19 (98Y) XL Star BMW M4 GTS - Tread Width 9.1"

Which one are you guys going with?


285/35 19 rear (Looks to be only 1 choice):

285/35ZR19 (103Y) XL - Tread Width 10"

I imagine the differences have to be small. I'd lean towards the GTS spec but I'd probably favor the cheapest first.

Has anyone used the Cup 2 on the front on the stock 19" rim?

The MO1 will be an updated version of the MO as specified by Mercedes.

I would choose star spec for M2 with the wider tread width than the GTS... which actually seems odd.

There's probably a minimal difference and you could go by price. I had to replace the non-type specific fronts on
my 1M with MO type and I couldn't tell
the difference, and lap times didn't change appreciably.

If I remember correctly when I was looking at this, the 265 M2 Spec is the only 265 Cup2 designed for a 9" rim width, which is what the front 437M is

I ended up ordering the Mercedes M01.
