i know youre against staggered because you want to rotate and get longer life, but bmw actually does not recommend rotating the tires because the car is AWD. That doesnt mean you cant do it.. I run a staggered set up for the summer and i really do feel a difference in handling and i do not think the ride is bumpy at all. Thats just my .02.

The simple answer is yes you can do non staggered, would i suggest it? probably not (mainly for cosmetic reasons)
