Infiniti QX56 wheel specs by year and trim
| Year | Model / trim | Bolt pattern | Center bore | OE wheel |
|---|---|---|---|---|
| 2008 | Infiniti QX56 | 6x139.7 | 77.8 mm | 20x8J ET25 |
| 2006 | Infiniti QX56 | 6x139.7 | 77.8 mm | 18x8J ET25 |
Factory wheel sizes on the Infiniti QX56
Across the 2 Infiniti QX56 trims with a documented factory wheel, the OE diameter is 18-20 inch, width 8J and offset ET25. A forged wheel that keeps the 6x139.7 bolt pattern and the 77.8 mm hub bore and stays inside that offset range 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 Infiniti QX56 (6x139.7, 77.8 mm Bore)
In our database, 27 other vehicle entries from 4 makes use exactly the same 6x139.7 bolt pattern and 77.8 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.
6x139.7 is used by 4.0% of the vehicle pages in our English fitment guide (258 of 6,503); 12.4% of those also use a 77.8 mm center bore.
Hub-Centric Rings for a 77.8 mm Center Bore
A wheel with a center bore larger than 77.8 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 78.1 mm | 78.1 → 77.8 mm |
| 84.1 mm | 84.1 → 77.8 mm |
| 93.1 mm | 93.1 → 77.8 mm |
| 100.1 mm | 100.1 → 77.8 mm |
ANKUSI forged wheels are bored to exactly 77.8 mm for this vehicle, so no ring is needed.

FAQ
What is the bolt pattern on a Infiniti QX56?
The Infiniti QX56 uses a 6x139.7 bolt pattern with a 77.8mm center bore across every QX56 variant in our database (2 guides, 2006–2008).
What is the Infiniti QX56 center bore?
The hub-centric center bore is 77.8 mm. Aftermarket wheels should match this bore or use hub-centric rings so the hub, not the bolts, carries the load.
Do all Infiniti QX56 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 Infiniti QX56?
Any wheel drilled 6x139.7 with a 77.8mm 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.
