Wasn't sure if this was better for rims and tire section or here but I've been all over this site and through tons of posts so figured I just get a straight answer.

Ordered 437's off one of the vendors here
They are 20-8.5 F and 9.5 R
So after all the research Im leaning towards
235-35 F and 275-30 R which would give me 26.5 total diameter which is .5 increase over stock
But would be equal increase front and back.
I don't want to stretch the tires due to the local roads
So figured this is the best fit.
Question I'm getting at is I'm leaning towards the eibach springs but wondering should I just run the xdrive set up and not the rwd set up due to increased tire diameter. .5 increase tire and .8-.6 lower suspension should be a good balance to get rid of the fender gap. Looking for some expert advice please.
New to the forum and this is my first BMW
Car is 2015 f30 335 m sport xdrive adaptive
It's my daily and I'm looking for appearance more so then a race car.

It's fine. I'm running the exact same setup on mine. With X drive, you just have to worry about the difference between front and rear rolling diameter to be no greater than 1%, which yours is.

The only issue with this setup is there's very little sidewall.

Cool thanks!
What springs are you running?
The xdrive or the rwd

RWD. The -02 set.
