BMW i4 G26 Facelift — Wheel Fitment & Specs
Overview
The BMW i4 (model code G26) is a battery electric compact executive car produced by BMW since October 2021. It features 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. Built on the modular CLAR platform to keep costs low and volume-production attainable, it uses the bodyshell design of the G26 4 Series Gran Coupé. It has a MacPherson strut front suspension and multi-link rear suspension with rear air suspension as standard (the M50 adds adaptive M dampers). The i4 was revealed fully production-ready in March 2021, three months ahead of schedule, and went on sale in November 2021.

Aftermarket wheel sizes — read per position:
| Position | Width | Offset |
|---|---|---|
| Front | 7.5J–8.5J | ET30–ET45 |
| Rear (staggered) | 9J–10J | ET36–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
Development began with an investment of about €200 million in the Munich plant to prepare for series production. This included converting over 1000 robots in the body shop and assembly area during a six-week closure in summer 2020. The electric motor is assembled at BMW Group Plant Dingolfing. Over an ownership period of 200,000 km (125,000 mi), the eDrive40 has a 45 percent lower global warming potential than comparable diesel models and uses recycled materials to cut production emissions by 18 percent.
