We recommend 245/40-19f, 275/35-19 to most customers because it has a taller sidewall which gives more ride comfort and has good availability so chances are someone can find this setup at their local distributor or tire rack. It isn't the only option and just because something is not on the guide doesn't mean it will never work. but for anyone going will a setup not on the guide, you'll need to be more well-versed in xDrive-compatible setups and the differences in widths than you would otherwise be going the easy route.
