I am just looking around for rims for my m340i touring. I would like to find out what the exact parameters should be for the rims in the rail size: 19'' and 20'' supposedly if you choose the wrong rims and wheels, there may be problems with drive.

I was inspired by these rims: https://www.2addicts.com/forums/bpga...=view&id=38441

You can use either 19 or 20 inch rims in the correct offset + width. If its an Xdrive you need to use a tyre diameter calculator to ensure that the rolling circumference of the front /rear tyres is within 1% to avoid potential transfer box issues. e.g. https://www.errolstyres.co.za/odcalculator

To be clear, within 1% of front to rear and not old tires/rims vs new tires/rims.
