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
A sedan's wheel spec is a balance point the factory tuned between ride comfort, steering feel, and everyday durability. Forging lets us hold that same structural margin while cutting rotational mass, which is where most of the real-world benefit — quicker steering response, marginally better ride — actually comes from.
The Infiniti Q70L runs a 5x114.3 bolt pattern, 66.1mm center bore, and a 18x8J at ET43, front and rear, wheel from the factory. Our Flush Fitment reference is 20x9J ET32, which tucks the tire under the fender lip on a stock-height Infiniti Q70L. Our Maximum Aggressive reference is 20x10J ET28 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Infiniti Q70L OE Wheel Specs
The 2015 Infiniti Q70L (Sedan) uses a 5x114.3 bolt pattern with a 66.1mm center bore. Factory wheels are 18x8J at ET43.
Why the factory spec works for most owners:
- Balances ride comfort with everyday fuel efficiency
- A widely used size in this segment, so tire and wheel availability stays strong
- Keeps unsprung weight low for stable, predictable handling
- Maintains clearance for the factory brake calipers and suspension components
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Infiniti Q70L (2015) we drill the 5x114.3 pattern and cut the centre bore to 66.1mm 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: Lowering springs. Tires: 245/50 R18.
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: 18x8J ET43 → ~6.19″ backspacing
- Flush: 20x9J ET32 → ~6.26″ backspacing
- Max: 20x10J ET28 → ~6.6″ 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 Q70L? 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 Q70L (5x114.3, 66.1 mm Bore)
In our database, 224 other vehicle entries from 9 makes use exactly the same 5x114.3 bolt pattern and 66.1 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.
5x114.3 is used by 20.0% of the vehicle pages in our English fitment guide (1,300 of 6,503); 17.3% 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.
Frequently Asked Questions
What bolt pattern (PCD) does the Infiniti Q70L use?
The 2015 Infiniti Q70L uses a 5x114.3 bolt pattern.
How many lug bolts does the Infiniti Q70L use?
The Infiniti Q70L uses a 5-lug bolt pattern (5x114.3), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Infiniti Q70L?
The Infiniti Q70L's center bore is 66.1mm. 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 Q70L?
Factory wheels on the Infiniti Q70L are 18x8J at ET43.
What is the biggest wheel size I can fit on my Infiniti Q70L without rubbing?
The most aggressive fitment we recommend without fender work is 20x10J at ET28 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 Q70L?
For a flush look with minimal to no rubbing, we recommend 20x9J at ET32 offset as a starting point on a stock or mildly lowered Infiniti Q70L.
Do I need wheel spacers for my Infiniti Q70L?
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 Q70L?
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 6.26" 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 Q70L?
The Infiniti Q70L 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.
