Depending on the model and its configuration, BMW7 series cars are equipped with tires and wheels of various sizes. For disks, in addition to the width of the disk, the pressing depth is also an important parameter. The pressing depth is the distance from the middle of the disc to the plane of contact between the disc and the brake disc.
All discs are so-called hill discs. A hill is a protrusion in the disc seat that prevents the tubeless tire from being pushed away from the disc during sharp turns.
Often, the documents for the car do not indicate which wheels and tires it is equipped with, so when installing new wheels, you need to make sure that the wheels are certified by BMW.
