Nissan 370Z / Infiniti Q50 Fitment · 5-Lug
Fitting Infiniti JX wheels? This page gives the 2013 Infiniti JX bolt pattern (5x114.3), centre bore, factory rim size and the offset range for aftermarket and forged Infiniti JX rims: the same spec sheet ANKUSI uses when machining forged wheels for this car.
Quick answer: The 2013 Infiniti JX uses a 5x114.3 bolt pattern with a 66.1 mm centre bore and M12x1.25 lug nuts. Factory wheels: 18x7.5J at ET50. For aftermarket wheels, 20x8.5J ET35 sits flush and 21x9J ET30 is the most aggressive fit.
Forged wheels for the 2013 Infiniti JX — drilled 5x114.3 with a 66.1 mm centre bore, built to the offset you choose. From $220 per wheel, made to order in about 25 days.

| Configuration | Wheel Size & Offset |
|---|---|
| Factory (OE) | 18x7.5J at ET50 |
| Flush Fitment | 20x8.5J at ET35 offset |
| Maximum Aggressive | 21x9J at ET30 offset |
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.


Because an SUV's center of gravity is already higher than a sedan's, anything added at the corners — including wheel weight — has an outsized effect on handling balance. A forged wheel lets us hit the visual stance owners want without adding the rotational mass a cast wheel of the same strength would carry.
The Infiniti JX runs a 5x114.3 bolt pattern, 66.1mm center bore, and a 18x7.5J at ET50, front and rear, wheel from the factory. Our Flush Fitment reference is 20x8.5J ET35, which tucks the tire under the fender lip on a stock-height Infiniti JX. Our Maximum Aggressive reference is 21x9J ET30 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
The 2013 Infiniti JX (SUV) uses a 5x114.3 bolt pattern with a 66.1mm center bore. Factory wheels are 18x7.5J at ET50.
Why the factory spec works for most owners:
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Infiniti JX (2013) 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.

For a flush look with minimal rubbing, 20x8.5J ET35 is the recommended starting point on a stock or mildly lowered Infiniti JX.
21x9J ET30 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

The examples below are compiled from typical ANKUSI customer configurations and are labeled as reference cases, not individually verified real-world builds.
Case 1: Daily Driver (Factory-Style)
Profile: Everyday driving, prioritizes comfort and low running cost.
Setup: 18x7.5J ET50
Cost: ~$620
Outcome: Minimal visual change, ride and fuel economy essentially unaffected.
Case 2: Balanced Enthusiast (Balanced / Flush Fit)
Profile: Wants a sportier stance without sacrificing daily usability.
Setup: 20x8.5J ET35
Cost: ~$3,000
Outcome: Noticeable visual upgrade, fuel economy drop within the expected range.
Case 3: Show Build (Max Aggressive)
Profile: Built primarily for shows or occasional track/show use.
Setup: 21x9.0J ET30
Cost: ~$5,500
Outcome: Maximum visual impact; daily comfort and fuel economy are heavily compromised, physical test fit required before production.
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
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 JX? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Everything above is reference data. If you want wheels actually built to it, that is what ANKUSI does: we are a forged wheel factory in Guangzhou, China, IATF 16949 and ISO 9001 certified, forging on our own 10,000-ton press and producing over 120,000 wheels a year. Forging blank, CNC machining, finishing, coating and inspection all happen in the same building — nothing is subcontracted and nothing is relabelled from another manufacturer.
Every set is cut to order, so the 5x114.3 pattern and the 66.1mm centre bore are machined for this car specifically rather than shimmed with adaptor rings. Diameter, width, offset, concavity, monoblock or multi-piece construction and the finish are all yours to choose — most Infiniti orders on this platform land somewhere between the 20x8.5J ET35 flush setup and the 21x9J ET30 aggressive setup referenced above.
Designs we already tool for the 5x114.3 pattern — each one is re-cut to your sizes and offsets:
ECC-Style Transparent Bronze Brushed 5 Y-Spoke Forged Wheels – Nissan 370Z / Infiniti Q50 Fitment (5-Lug)
Infiniti OEM-Style Chrome 6 Twin-Spoke Forged Wheels – Infiniti Q50 / Q60 Fitment (5-Lug)

Nissan 370Z / Infiniti Q50 Forged Wheels – Matte Black Rotor Disc 2-Piece Polished Deep Lip (5-Lug)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.
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.
