Vehicles With the Same Hub as the Smart forfour (4x100, 60.1 mm Bore)
In our database, 141 other vehicle entries from 9 makes use exactly the same 4x100 bolt pattern and 60.1 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.
4x100 is used by 6.9% of the vehicle entries in our database (451 of 6,503); 33.3% of those also use a 60.1 mm center bore.
Offset and Backspacing: Factory Wheel vs Options
Backspacing ≈ width/2 + ET/25.4 + 0.5 in. "Inward" means closer to the suspension; "outward" means closer to the fender lip.
| Setup | Size | ET | Backspacing | Inward vs OE | Outward vs OE |
|---|---|---|---|---|---|
| Factory (OE) | 15x5J | ET32 | 4.26 in (108 mm) | — | — |
| Flush | 16x6J | ET30 | 4.68 in (119 mm) | +11 mm | +15 mm |
| Maximum | 17x7J | ET28 | 5.10 in (130 mm) | +21 mm | +29 mm |
Hub-Centric Rings for a 60.1 mm Center Bore
A wheel with a center bore larger than 60.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 63.4 mm | 63.4 → 60.1 mm |
| 64.1 mm | 64.1 → 60.1 mm |
| 65.1 mm | 65.1 → 60.1 mm |
| 66.1 mm | 66.1 → 60.1 mm |
| 73.1 mm | 73.1 → 60.1 mm |
ANKUSI forged wheels are bored to exactly 60.1 mm for this vehicle, so no ring is needed.

FAQ
What is the bolt pattern on a Smart forfour?
The Smart forfour uses a 4x100 bolt pattern with a 60.1mm center bore across every forfour variant in our database (2 guides, 2015–2017).
What is the Smart forfour center bore?
The hub-centric center bore is 60.1 mm. Aftermarket wheels should match this bore or use hub-centric rings so the hub, not the bolts, carries the load.
Do all Smart forfour years share the same wheel fitment?
The bolt pattern and center bore are the same across the years we cover, but OE wheel width and offset differ by trim, so check the exact model line before choosing an aftermarket size.
Which forged wheels fit the Smart forfour?
Any wheel drilled 4x100 with a 60.1mm 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.
