Factory wheel sizes on the BMW 4 Series
Across the 14 BMW 4 Series trims with a documented factory wheel, the OE diameter is 17-19 inch, width 7.5-8J. A forged wheel that keeps the bolt pattern and hub bore of your generation (see the table above) and matches the factory offset listed on the model page bolts on without spacers or hub rings. Going one inch up in diameter with a lower-profile tyre keeps the rolling circumference inside the usual 1.5% tolerance; every extra 0.5J of width moves the outer lip about 6 mm outward at the same offset, and each 5 mm less offset moves the whole wheel 5 mm outward.

Vehicles With the Same Hub as the BMW 4 Series (5x120, 72.6 mm Bore)
In our database, 91 other vehicle entries from 9 makes use exactly the same 5x120 bolt pattern and 72.6 mm center bore. Factory wheels from these cars bolt on and center on the hub without rings; offset and width still have to be checked.
5x120 is used by 10.3% of the vehicle entries in our database (667 of 6,503); 50.8% of those also use a 72.6 mm center bore.
Hub-Centric Rings for a 72.6 mm Center Bore
A wheel with a center bore larger than 72.6 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 73.1 mm | 73.1 → 72.6 mm |
| 74.1 mm | 74.1 → 72.6 mm |
| 76.1 mm | 76.1 → 72.6 mm |
| 78.1 mm | 78.1 → 72.6 mm |
ANKUSI forged wheels are bored to exactly 72.6 mm for this vehicle, so no ring is needed.
Sources and Last Update
Bolt pattern and center bore were checked against at least two independent fitment references before publication.

FAQ
What is the bolt pattern on a BMW 4 Series?
The BMW 4 Series uses a 5x120 bolt pattern on most variants we cover with a 72.6mm center bore. Other generations use 5x112 / 66.6mm (2021–2025). Always check the exact year and trim before ordering.
What is the BMW 4 Series center bore?
The hub-centric center bore is 72.6 mm on the most common generation; see the table for variants. Aftermarket wheels should match this bore or use hub-centric rings so the hub, not the bolts, carries the load.
Do all BMW 4 Series years share the same wheel fitment?
No. The bolt pattern or center bore changed between generations, so wheels are not interchangeable across all years. Use the year-by-year table on this page to pick the right specification.
Which forged wheels fit the BMW 4 Series?
Any wheel drilled 5x120 with a 72.6mm hub bore in the offset range shown on the model guide. ANKUSI forges wheels to order for this exact specification, in 14–24 inch diameters, so no adapters or hub rings are needed.
