I'm running staggered 235/35 - 275/30 on 19's with my E92 Xi mostly for looks...I have noticed a bit less of a steering response and i'm still trying to figure out why. Even though my new tires grip extremely well in the turns...I have to turn the steering wheel more each direction to get a response than I had to running my stock 17 inch set-up (non-staggered). Maybe it's just the combo of running such an aggressive set-up with AWD?? If someone else could verify or help give me a reason why It takes a bit more turning of the wheel to steer and why the steering would be less responsive overall, I'd appreciate it.

(PS- Running this set-up brings the speedometer to a much more accurate reading, which is neat)
