Mein Auto: 535i xDrive, C4S cab
short version.

xDrive cars in the US come with the same size tires all around, on a 550i(or 535i) xDrive M Sport it would be 245/40-19. If you have a 550i then staggered 245/40-19 on front and 275/35-19 rear, I believe. The diameters are the same (within a fraction) but more width on the rears, for the RWD.

With winter tires width is usually not a good thing so you'd run with the narrower tires all around.

On the 18" wheels, you'd go 245/45-18 all around. Staggered you'd be 245/45-18 front and 275/40-18 rear.

For summer tires, yes the Michelin Pilot Super Sport looks great from some reviews and first adopters. They are very new, just released this month.
