BMW i4 G26 — Wheel Fitment & Specs
Overview
The BMW i4 (model code G26) is a battery electric compact executive car produced by BMW since October 2021. It has a five-door liftback body style and is marketed as a four-door coupé. The initial concept version, named BMW i Vision Dynamics, debuted at the 2017 Frankfurt Motor Show. It is the fifth BMW i sub-brand model, and is sold in several variants at different performance levels, including the first battery-electric variant by BMW's motorsport division. The production version was revealed in March 2021 and went on sale in November of the same year as a 2022 model.

Aftermarket wheel sizes — read per position:
| Position | Width | Offset |
|---|---|---|
| Front | 7.5J–8.5J | ET30–ET45 |
| Rear (staggered) | 9J–10J | ET33–ET45 |
As a rule, each extra 1J of width wants roughly +8–10 ET to keep the wheel tucked. The exact offset and any spacer are confirmed by the fit-check.
UK popularity & demand
Based on DfT VEH0124 vehicle-parc data (2025), there are approximately 39,484 BMW i4 on UK roads, placing it in the top 7% of car models by volume across our fitment database. That makes its wheel fitment a high-demand size to keep in stock — one reason we track its exact spec here.

History & notable variants
An investment of about €200 million in the Munich plant was made to prepare for the series production of the G26 BMW i4, which is built on the same assembly line as cars with combustion engines and plug-in hybrids. The plant underwent significant modifications, including converting over 1000 robots in the body shop and assembly area during a six-week closure in summer 2020 to prepare for the production of the i4. The electric motor is assembled at BMW Group Plant Dingolfing. The i4 was revealed fully production-ready in March 2021, three months ahead of schedule.
