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
The Infiniti QX's factory suspension tuning already accounts for a specific unsprung mass target. Forged construction lets ANKUSI match the factory strength spec while keeping rotational weight down, which is where the real handling benefit comes from on a taller, heavier SUV platform.
The Infiniti QX runs a 6x139.7 bolt pattern, 78.1mm center bore, and a 20x8J at ET35, front and rear, wheel from the factory. Our Flush Fitment reference is 22x9.5J ET20, which tucks the tire under the fender lip on a stock-height Infiniti QX. Our Maximum Aggressive reference is 24x10J ET15 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Infiniti QX OE Wheel Specs
The 2011 Infiniti QX (SUV) uses a 6x139.7 bolt pattern with a 78.1mm center bore. Factory wheels are 20x8J at ET35.
Why the factory spec works for most owners:
- Supports the vehicle's curb weight and load capacity
- Preserves ground clearance for everyday and light off-road use
- Balances ride comfort with cargo and passenger stability
- Maintains clearance for the factory suspension travel and brake package
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Infiniti QX (2011) we drill the 6x139.7 pattern and cut the centre bore to 78.1mm 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.

Real-World Fitment Notes
Chassis: Air lowering links. Wheels: Heavy-duty 6-lug. Tires: 275/60 R20.
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: 20x8J ET35 → ~5.88″ backspacing
- Flush: 22x9.5J ET20 → ~6.04″ backspacing
- Max: 24x10J ET15 → ~6.09″ backspacing
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 Infiniti spec, or want a wheel built to a custom offset for your Infiniti QX? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Vehicles With the Same Hub as the Infiniti QX (6x139.7, 78.1 mm Bore)
In our database, 79 other vehicle entries from 5 makes use exactly the same 6x139.7 bolt pattern and 78.1 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.
6x139.7 is used by 4.0% of the vehicle pages in our English fitment guide (258 of 6,503); 31.0% of those also use a 78.1 mm center bore.
Hub-Centric Rings for a 78.1 mm Center Bore
A wheel with a center bore larger than 78.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 84.1 mm | 84.1 → 78.1 mm |
| 93.1 mm | 93.1 → 78.1 mm |
| 100.1 mm | 100.1 → 78.1 mm |
| 106.1 mm | 106.1 → 78.1 mm |
ANKUSI forged wheels are bored to exactly 78.1 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the Infiniti QX use?
The 2011 Infiniti QX uses a 6x139.7 bolt pattern.
How many lug bolts does the Infiniti QX use?
The Infiniti QX uses a 6-lug bolt pattern (6x139.7), so you need a 6-lug forged wheel to bolt straight on.
What is the center bore size on the Infiniti QX?
The Infiniti QX's center bore is 78.1mm. 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 Infiniti QX?
Factory wheels on the Infiniti QX are 20x8J at ET35.
What is the biggest wheel size I can fit on my Infiniti QX without rubbing?
The most aggressive fitment we recommend without fender work is 24x10J at ET15 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 Infiniti QX?
For a flush look with minimal to no rubbing, we recommend 22x9.5J at ET20 offset as a starting point on a stock or mildly lowered Infiniti QX.
Do I need wheel spacers for my Infiniti QX?
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 Infiniti QX?
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 6.04" 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 Infiniti QX?
The Infiniti QX 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.
