Because if your tire size is 255/35-19, 35 is the ratio of the height to the width. In other words, it's a percentage of the width of the tire. So to have the same diameter size of a wider tire, you need a smaller aspect ratio.
xDrive has a transfer case so all 4 tires needs to be within 1% of each other.
