2021 BMW i4 Wheel & Fitment FAQs
What is the exact wheel bolt pattern, hub bore, and lug specification for the 2021 BMW i4?
The 2021 BMW i4 is engineered with a 5x112 bolt pattern and a 66.6 mm center bore and accommodates wheel diameters of 17"–20" with rim widths of 7.5"–9". Installing hub-centric wheels guarantees zero highway vibrations.
Do different 2021 BMW i4 trims share the same wheel size and brake clearance?
Across 2021 BMW i4 trims (eDrive40, xDrive40), compatible wheels span 17"–20" in diameter and 7.5"–9" wide with offsets around ET30–ET42 (5x112 bolt pattern). Higher trims equipped with upgraded sport brakes require larger wheel diameters to clear the calipers.
What axle load rating should I select for aftermarket wheels on the 2021 BMW i4?
Because the 2021 BMW i4 carries substantial EV battery weight, aftermarket wheels must meet or exceed OEM axle load ratings on the 5x112 bolt pattern (17"–20" sizes). Flow-formed or forged alloy construction also optimizes driving range.
What factory and plus-sized tire sizes fit the 2021 BMW i4?
Recorded compatible tire sizes for the 2021 BMW i4 include 225/55ZR17 101Y XL, 245/45ZR18 100Y XL, 225/55R17 101H XL, 245/40ZR19 98Y XL, 255/40ZR19 100Y XL on 17"–20" wheels. When building a package, our fitment engine confirms exact tire aspect ratios for your selected rim width.
