I've found the steering of BMWs to be inconsistent. The previous gen X5 had brutal steering. I then drove a 2011 X6 with 20s and the steering was much lighter. In in the past I've even test drove a 7 series without sport package (smaller wheels) and one with sports package and guess what? The one WITHOUT sports package had much tighter (firmer) steering.
So it is hit or miss. Do stay away from my old 2012 X6 50i with Active Steering - cause you won't like that!
