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
Most of the engineering value in a forged wheel over a cast one shows up in rotational mass, not outright strength — both can meet the same load rating, but the forged piece gets there lighter. On a sedan platform tuned for everyday balance, that weight saving is felt directly in steering response and ride quality.
The Seat Mii Electric runs a 4x100 bolt pattern, 57.1mm center bore, and a 16x6.0J, front and rear, wheel from the factory. Our Flush Fitment reference is 17x7.5J ET35, which tucks the tire under the fender lip on a stock-height Seat Mii Electric. Our Maximum Aggressive reference is 17x8.5J ET30 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Seat Mii Electric OE Wheel Specs
The 2020 Seat Mii Electric (City EV) uses a 4x100 bolt pattern with a 57.1mm center bore. Factory wheels are 16x6.0J F/R.
Why the factory spec works for most owners:
- Balances ride comfort with everyday drivability
- A commonly used size for this vehicle class, supporting parts and tire availability
- Maintains clearance for the factory suspension and brake components
- Provides stable, predictable handling across normal driving conditions
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Seat Mii Electric (2020) we drill the 4x100 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.

A Note on Clearance
Final clearance depends on the exact tire model, suspension height, brake package, alignment and vehicle tolerances. A physical test fit is recommended before production.
Want to check a different width or offset before you order? Use our Offset & Backspacing Calculator to solve the numbers yourself, or looking for your exact Seat spec, or want a wheel built to a custom offset for your Seat Mii Electric? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
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) | 16x6J | ET35 | 4.88 in (124 mm) | — | — |
| Flush | 17x7.5J | ET35 | 5.63 in (143 mm) | +19 mm | +19 mm |
| Maximum | 17x8.5J | ET30 | 5.93 in (151 mm) | +27 mm | +37 mm |
Vehicles With the Same Hub as the Seat Mii Electric (4x100, 57.1 mm Bore)
In our database, 37 other vehicle entries from 7 makes use exactly the same 4x100 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.
4x100 is used by 6.9% of the vehicle pages in our English fitment guide (451 of 6,503); 8.4% 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.
Frequently Asked Questions
What bolt pattern (PCD) does the Seat Mii Electric use?
The 2020 Seat Mii Electric uses a 4x100 bolt pattern.
How many lug bolts does the Seat Mii Electric use?
The Seat Mii Electric uses a 4-lug bolt pattern (4x100), so you need a 4-lug forged wheel to bolt straight on.
What is the center bore size on the Seat Mii Electric?
The Seat Mii Electric's center bore is 57.1mm. If an aftermarket wheel has a larger center bore than this, hub-centric rings are recommended so the wheel centers on the hub itself rather than relying on the lug bolts alone.
What size are the factory (stock) wheels on the Seat Mii Electric?
Factory wheels on the Seat Mii Electric are 16x6.0J F/R.
What is the biggest wheel size I can fit on my Seat Mii Electric without rubbing?
The most aggressive fitment we recommend without fender work is 17x8.5J at ET30 offset. Going beyond this typically causes rubbing under compression unless you roll the fenders or add camber correction.
What does a flush wheel fitment look like on the Seat Mii Electric?
For a flush look with minimal to no rubbing, we recommend 17x7.5J at ET35 offset as a starting point on a stock or mildly lowered Seat Mii Electric.
Do I need wheel spacers for my Seat Mii Electric?
No. ANKUSI forges each wheel to your exact target offset, including the flush or max specs above, so you get the correct fitment without stacking spacers. Spacers are typically only used to push out an existing OE-offset wheel without replacing it, which isn't necessary when you're ordering a custom-offset forged wheel.
How do I calculate wheel backspacing for my Seat Mii Electric?
Backspacing (in inches) = wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance). For example, the flush spec above works out to roughly 5.63" of backspacing.
What's the difference between wheel offset and backspacing?
Offset is the distance in millimeters from the wheel's true centerline to its mounting face (positive offset pulls the wheel in, negative pushes it out). Backspacing is the distance in inches from the mounting face to the back edge of the wheel barrel. They describe the same fitment from two different reference points, which is why ANKUSI lists both above — some shops and tuning guides quote offset, others quote backspacing.
Can I run staggered wheels (different sizes front and rear) on my Seat Mii Electric?
The Seat Mii Electric runs the same wheel size front and rear from the factory, so staggered fitment is not required. ANKUSI can still forge a staggered set (wider rear) on request if you want a more aggressive stance.
