BMW 4 Series G22/G23 LCI — Wheel Fitment & Specs
Overview
The BMW 4 Series is a compact executive car manufactured by BMW since 2013, spun off from the 2-door models (coupé and convertible) of the 3 Series. The current generation, introduced in June 2020, distinguishes itself with a large kidney grille design inspired by the 1930s BMW 328. It is produced alongside the G20 3 Series and shares many features with it.

Aftermarket wheel sizes — read per position:
| Position | Width | Offset |
|---|---|---|
| Front | 7J–8J | ET18–ET27 |
| Rear (staggered) | 8J–9.5J | ET29–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 113,829 BMW 4 Series on UK roads, placing it in the top 3% 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.
