Aftermarket wheel sizes — read per position:
| Position | Width | Offset |
|---|---|---|
| Front | 6.5J–8.5J | ET24–ET45 |
| Rear (staggered) | 8J–10J | ET33–ET50 |
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.

History & notable variants
The original concept car was unveiled at the North American International Auto Show in January 2013. The second generation introduced significant styling changes to move the model upscale, including a larger front grille inspired by the BMW 328 of the 1930s. In January 2021, the 420i M Sport was named 'Coupé of the Year' by What Car? magazine and received a five-star review.
