although you may have more lateral grip, wider, taller, heavier tires negatively affect acceleration and braking due to increased rolling resistance, rotational inertia and taller gearing.

bmw offers staggered wheels as an option or part of a package on x-drives.

due to the x-drive transfer case, the difference between front and rear tire diameters should be less than 1%(equal is ideal), however i've seen people run outside of this tolerance without issue.
