BMW M641 wheels from M3 to M2

Egress · 11-23-2017, 11:10 PM

I don‘t know if any of you have ever seen the M641 wheel design so I will include a picture. Yesterday a saw a M3 on its Winter tire setup and this was the M641 wheel. I love it and as I was on my way to a painter to let him paint my original wheels silver I am not quite sure if shoul do it now or just sell them and buy different wheels such as the 641.
After some research I found out they are front 8.5x19 ET 27 and rear 9x19 ET 29. I would want to run Pilot Sport Cup 2 tired in stock dimensions 245/35 and 265/35.
My question is: the wheels are a half inch in front and one inch in rear narrower than stock, how could this affect the tires? I mean bmw must have had a reason for picking the 9 and 10 inch wheels for the M2.
I would like to know if this setup would be negative for the tires and their behaviour.
Thanks for your inputs

The 641m and MPSC2 combo will work fine.

Have you tried it? Have you got pictures? I am specially interested in how far the tire stays out of the wheel if you know what I mean

I have already seen those pics but they are all with winter tires which are only 235 or 245
I would want pics where a 245 and 265 is mounted to check out how it looks...

Run your configuration through this app and you'll get your answer: I found this great Tire and Wheel Size Calculator: it does conversions and will calculate wheel and tire fit. It also calculates Speedometer Error and Rolling Radius. The Wheel Fitment app by Nikita Morozov is located in the App Store or click here: https://itunes.apple.com/us/app/tire...892154550?mt=8
