if you go 295 in the rear you would need a different tire up front since you have an xdrive car. the overall diameter needs to be same.
If you go find a online tire calculator you can see just how much it will be off by. There is a certain limit that xdrive cars can run where it wouldn't freak out the system but nobody know for sure what that limit is.
I find it strange that bmw runs 245/35 and 275/30 tires on their cars when its not as perfect as 245/285 combo (overall diameter)
