what are you guys running for winter?

im looking at the michelin PAPA4 on tirerack but they only come in 245/35.
would it mess up anything if i run it on the front and rear?

[chris719]

You need a narrower wheel to run 245 in the rear. You can buy 2 more front wheels though, the offset works out about the same with the width difference. If you want an OEM look I would buy 4 front 437M or 4 front 763M and run 245/35 square or maybe 245/255.

Mine were put on this morning. 640M.

18 inch 235/35 F and 255/35 R(rear brandnew ones Pilot Alpin) andv they don't look bad at all. It's now 3 degrees Celsius (37F)and a lot of rain(yesterday snowy) . Steering feels lighter but still pointing in is A+ in this kind of weather. Traction too. In-cre-di-ble.But still easily driftable(this is also my driftday set lol)




Cheers

Based on the tire sizes I saw, probably best to pick up an 18" wheel to get more options.

OP is in the US - no 18's on our silly brakes. 641's are the BMW "winter" wheels for BBK-equipped M2C's (or 437's and other 19's).

[chris719]

If you can afford it, the absolute best setup for an M2C is four front 9x19" 763M and 245/35/19 front and 245/35/19 or 255/35/19 rear.

18 inch wont fit the factory big brake, unless you don't have that option in Europe, etc

and stock size
245/35/19 michlin alpine 4a,
will RUB slightly when you do full turn

winter tires are taller in general

[chris719]

Has anyone been able to replicate the rubbing other than you?

The official specs show it is not taller than the BMW star spec PSS. The overall diameter is 25.7" for the PA4 and 25.8” for PSS. It seems highly unlikely it would rub.

i can confirm rubbing up front with square 255/35/19 pirellis.

[Gearhead999s]

Mine rubbed with 255/35 19's up front so I am running a 245/35 19 square for the winter.

Yes, that's 255, not 245. 245 is the stock size. Twboy is reporting rubbing with 245s.

Curious that you guys are seeing rubbing. My LCI has 265/35r19 blizzaks on the front and it only rubs a little at full turn.

[crc13549]

Yes, my 245/35/19 michelin alpins do rub in the front near full lock. They are mounted on the stock 788s.

What options do i have if i switch out the stock 2NH brake calipers? What calipers would i be able to use instead with say 18s instead of the 19s?

OG M2/M3/M4 blue brakes or something like AP racing

[pizza240]

437M with Pirelli Sottozero Serie 3 245 front 265 rear. The rears weren't cheap but they stick. Ran 225s all around on my M240ix and thought they were fantastic. Not sure why people dislike these tires! They're great.

[dlong82]

Ordered BMW recommended winter set with the car (US).
Wheels: 641M, square, 19" by 8.5".
Tires: Michelin Pilot Alpin PA4 non-runflat (235/35R19).
Have had the Alpin on other cars and thought they performed very well.
