Data sources and methodology
SteeringWheelSize.com compiles steering wheel size data from model-year references, manufacturer materials, parts listings, and marketplace sources. The table on this page presents the measurements as diameter x grip circumference.
Trim rows and size classifications are shown when that information is available for the BMW 8 Series. Always verify fitment on the wheel before driving with an installed cover.
