I have an '02 E39 M62 I am upgrading the tires and wheels to 17" NON STAGGERED.

The car calls for 235/45/17's... Can I go with 235/40/17's instead without fudging with the suspension whatsoever... ?

New Wheels are 17 X 8 on all 4 corners. What are the challenges if any? If the turning radius is shortened I'm okay with that as I'll just go slower in parking lots-I don't think it will be so severe that I can't grow accustomed to it. Other than that please chime in.

Thanks in advance!
