BMW 4 Series Gran Coupe G26 — Wheel Fitment & Specs
Overview
The BMW 4 Series Gran Coupe G26 is part of the second generation of the BMW 4 Series compact executive cars manufactured by BMW since June 2020. It is produced alongside the G20 3 Series and shares many features with it, including turbocharged petrol and diesel engines. The G26 model code represents a significant design change from its predecessor, featuring a large kidney grille at the front to distinguish itself from the 3 Series and move upscale in market positioning.

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.
