Tire size for xi

Hey guys

I picked up a set of oem style 197 for my e46 330xi, and want to get rid of the run flat tires.

The rims are

FRONT: 18x8.0 ET34
REAR: 18x8.5 ET37

I read online that i will stay within the 3% rolling diameter if i run 225/40s up front and 255/35s in the rear. Can anyone confirm this for me, or have any other tire suggestions


F15 35d m sport - e34 M5 - e46 330xi m sport- e28 M5
