Seat Mii wheel specs by year and trim
| Year | Model / trim | Bolt pattern | Center bore | OE wheel |
|---|---|---|---|---|
| 2020 | Seat Mii Electric | 4x100 | 57.1 mm | 16x6.0J |
| 2014 | Seat Mii | 4x100 | 57.1 mm | 14x5.0J |
Factory wheel sizes on the Seat Mii
Across the 2 Seat Mii trims with a documented factory wheel, the OE diameter is 14-16 inch, width 5-6J. A forged wheel that keeps the 4x100 bolt pattern and the 57.1 mm hub bore 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 Seat Mii (4x100, 57.1 mm Bore)
In our database, 35 other vehicle entries from 6 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 entries in our database (451 of 6,503); 8.4% of those also use a 57.1 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) | 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 |
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.

FAQ
What is the bolt pattern on a Seat Mii?
The Seat Mii uses a 4x100 bolt pattern with a 57.1mm center bore across every Mii variant in our database (2 guides, 2013–2020).
What is the Seat Mii center bore?
The hub-centric center bore is 57.1 mm. Aftermarket wheels should match this bore or use hub-centric rings so the hub, not the bolts, carries the load.
Do all Seat Mii 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 Seat Mii?
Any wheel drilled 4x100 with a 57.1mm 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.
