Greetings. We picked up a new to us 2013 528 x Drive today. It has the M Sport package on it. I was expecting to see wider rear wheels/tires, but it seems that they are not staggered. I've searched the forums and Dr. Google, and cannot for the life of me find out what was stock on x Drive cars; square or staggered?

Any help would be greatly appreciated.

Thanks, Aaron
