How to Read Wheel Offset & Measurements
Use these two references before ordering: the left diagram shows where each spec (PCD, center bore, offset, width and diameter) is measured on the wheel; the right diagram shows how positive, zero and negative offset shift the wheel face relative to the hub centerline.
ANKUSI Engineering Expert Advice
A sedan's wheel spec is a balance point the factory tuned between ride comfort, steering feel, and everyday durability. Forging lets us hold that same structural margin while cutting rotational mass, which is where most of the real-world benefit — quicker steering response, marginally better ride — actually comes from.
The Smart fortwo edition red ships from the factory on a 3x112 bolt pattern with a 57.1mm center bore and a F 15x4J ET27 / R 15x5.5J ET-1 wheel. Our flush reference for the Smart fortwo edition red is F 16x5.5J ET22 / R 16x6.5J ET-5.; our maximum aggressive reference is F 16x6J ET20 / R 16x7.5J ET-10. — beyond that, expect clearance issues against the fender liner without further modification.
Smart fortwo edition red OE Wheel Specs
The Smart fortwo edition red ships from the factory on 3x112 bolt pattern wheels with a 57.1mm center bore. The stock wheel size is F 15x4J ET27 / R 15x5.5J ET-1, offering a balanced ride that suits most owners without any rubbing or clearance concerns.
Why the factory spec works for most owners:
- Balances ride comfort with steering response and highway efficiency.
- Wide tire and wheel availability at the factory diameter keeps replacement costs low.
- Lower unsprung weight than larger aftermarket wheels helps ride quality and acceleration.
- Guaranteed clearance against brake calipers and suspension components.
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Smart fortwo edition red (2006) we drill the 3x112 pattern and cut the centre bore to 57.1mm on our own CNC line, so the wheel hub-centres on the car with no spacer rings, in whatever diameter, width and offset you specify.

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) | 15x4J | ET27 | 3.56 in (90 mm) | — | — |
| Flush | 16x5.5J | ET22 | 4.12 in (105 mm) | +14 mm | +24 mm |
| Maximum | 16x6J | ET20 | 4.29 in (109 mm) | +18 mm | +32 mm |
Vehicles With the Same Hub as the Smart fortwo edition red (3x112, 57.1 mm Bore)
In our database, 12 other vehicle entries from 2 makes use exactly the same 3x112 bolt pattern and 57.1 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.
3x112 is used by 0.2% of the vehicle pages in our English fitment guide (13 of 6,503); 100.0% of those also use a 57.1 mm center bore.
Hub-Centric Rings for a 57.1 mm Center Bore
A wheel with a center bore larger than 57.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 60.1 mm | 60.1 → 57.1 mm |
| 63.4 mm | 63.4 → 57.1 mm |
| 64.1 mm | 64.1 → 57.1 mm |
| 65.1 mm | 65.1 → 57.1 mm |
| 73.1 mm | 73.1 → 57.1 mm |
ANKUSI forged wheels are bored to exactly 57.1 mm for this vehicle, so no ring is needed.
