Factory wheel sizes on the BMW M135i
Across the 5 BMW M135i trims with a documented factory wheel, the OE diameter is 18 inch, width 7.5-8J and offset ET45-50. A forged wheel that keeps the bolt pattern and hub bore of your generation (see the table above) and stays inside that offset range 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 M135i (5x112, 66.6 mm Bore)
In our database, 632 other vehicle entries from 20 makes use exactly the same 5x112 bolt pattern and 66.6 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.
5x112 is used by 21.9% of the vehicle entries in our database (1,403 of 6,396); 58.6% of those also use a 66.6 mm center bore.
Hub-Centric Rings for a 66.6 mm Center Bore
A wheel with a center bore larger than 66.6 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 67.1 mm | 67.1 → 66.6 mm |
| 70.1 mm | 70.1 → 66.6 mm |
| 70.5 mm | 70.5 → 66.6 mm |
| 71.6 mm | 71.6 → 66.6 mm |
| 73.1 mm | 73.1 → 66.6 mm |
ANKUSI forged wheels are bored to exactly 66.6 mm for this vehicle, so no ring is needed.

FAQ
What is the bolt pattern on a BMW M135i?
The BMW M135i uses a 5x112 bolt pattern on most variants we cover with a 66.6mm center bore. Other generations use 5x120 / 72.6mm (2013–2016). Always check the exact year and trim before ordering.
What is the BMW M135i center bore?
The hub-centric center bore is 66.6 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 M135i 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 M135i?
Any wheel drilled 5x112 with a 66.6mm 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.
