2018 BMW i8 Wheel & Fitment FAQs
What is the exact wheel bolt pattern, hub bore, and lug specification for the 2018 BMW i8?
The 2018 BMW i8 is engineered with a 5x112 bolt pattern and a 66.5 mm center bore and accommodates wheel diameters of 20" with rim widths of 7"–8.5". Installing hub-centric wheels guarantees zero highway vibrations.
Do different 2018 BMW i8 trims share the same wheel size and brake clearance?
Across 2018 BMW i8 trims (1.5), compatible wheels span 20" in diameter and 7"–8.5" wide with offsets around ET36–ET50 (5x112 bolt pattern). Higher trims equipped with upgraded sport brakes require larger wheel diameters to clear the calipers.

Because the 2018 BMW i8 carries substantial EV battery weight, aftermarket wheels must meet or exceed OEM axle load ratings on the 5x112 bolt pattern (20" sizes). Flow-formed or forged alloy construction also optimizes driving range.
