This is for rwd only. I am trying to find real world results of mismatching diameters from front to rear. I am aware that x drive asks that you keep it below 1% delta. But there does not seem to be an official word on what the rwd abs/dsc will tolerate. I have been compiling a list of what has worked for other chassis, but there is not a lot for e60's. I tried a few years ago (I will update the size when I get home) to run a taller tire in the rear, dsc/abs lights all over the place, car was not happy unless i fully disabled dsc...... so I know there is a limit to the mismatch on rwd vehicles.

Please share your front and rear rubber, bonus points for rim size/offset!
