Basically, your new set "rolling diameter" needs to stay within <=3% (preferablly <1%) of the original set, moreover-especially with xDrive-the difference between the rolling diameter of the new Front set compared to the new rear set should optimally stay below 1%.
Here is a good tire size calculator that I have been using for that purpose:
My stock sizes are 245 40 19 i believe the rims are 19x8 or 8.5non staggered setup due to the xdrive. Historically, on the e60s the staggered 19x8.5 (front) 19x9(rear) setup would not fit or was not rec due to rubbing or what not but i am not sure about the F10s.
