What is the width of your wheels? I believe the stock 220 wheels had a width of 8.5" front and 9.5 rear. I haven't fooled with them for awhile. With that width wheel on a 5 series car you should b e running 245/40-19 (Front) and 275/35-19 (rear) and your speedometer will be correct as much as the OEM wheels. There will be about 1/8" difference height between front and rear. That is what I ran on my E60 535i Xdrive. Now, for the next problem. I tried to install a set of 220 M3 wheels on my E60. The M3 220 wheel has practically NO offset and I quickly decided they would not work. The spacer required to make them work would be enormous. Seems to me that because of the small offset it would hit the inside of the inner fender. Like I said, been a long time since I fooled with the. As far as the wobble, check the wheels and make sure they don't have a reducing ring in the bore. I ran across that also. I always liked the 220 wheel but not satisfactory for a 5 series.
