It's important to note that these are made for temporary and limited use, meant to get you to a service station. In terms of size, it varies depending on the model year of the BMW 550i, but the general sizing is around 18-20 inches. It is crucial to get the correct size, type, and tread for safety and compatibility with the vehicle's existing tires.
