AITO M8 wheel specs by year and trim
| Year | Model / trim | Bolt pattern | Center bore | OE wheel |
|---|---|---|---|---|
| 2026 | AITO M8 | 5x120 | 66.1 mm | 20x8.5J |
| 2025 | AITO M8 | 5x120 | 66.1 mm | 20x8.5J |
Factory wheel sizes on the AITO M8
Across the 2 AITO M8 trims with a documented factory wheel, the OE diameter is 20 inch, width 8.5J. A forged wheel that keeps the 5x120 bolt pattern and the 66.1 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 AITO M8 (5x120, 66.1 mm Bore)
No other make in our database pairs 5x120 with a 66.1 mm center bore, so wheels taken from other brands need a hub-centric ring or a custom bore.
5x120 is used by 10.3% of the vehicle entries in our database (667 of 6,503); 0.4% of those also use a 66.1 mm center bore.
Hub-Centric Rings for a 66.1 mm Center Bore
A wheel with a center bore larger than 66.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 66.6 mm | 66.6 → 66.1 mm |
| 67.1 mm | 67.1 → 66.1 mm |
| 70.1 mm | 70.1 → 66.1 mm |
| 70.5 mm | 70.5 → 66.1 mm |
| 73.1 mm | 73.1 → 66.1 mm |
ANKUSI forged wheels are bored to exactly 66.1 mm for this vehicle, so no ring is needed.

FAQ
What is the bolt pattern on a AITO M8?
The AITO M8 uses a 5x120 bolt pattern with a 66.1mm center bore across every M8 variant in our database (2 guides, 2025–2026).
What is the AITO M8 center bore?
The hub-centric center bore is 66.1 mm. Aftermarket wheels should match this bore or use hub-centric rings so the hub, not the bolts, carries the load.
Do all AITO M8 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 AITO M8?
Any wheel drilled 5x120 with a 66.1mm 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.
