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
SUVs carry more curb weight higher off the ground, so wheel strength and rotational mass both matter more than on a comparable sedan — a heavier wheel amplifies body roll and slows steering response exactly where the platform is already working hardest. Forging keeps the wheel light without giving up the load rating the factory suspension geometry was tuned around.
The Hyundai Ioniq 9 ships from the factory on a 5x114.3 bolt pattern with a 67.1mm center bore and a 20x8.5J ET45 wheel. Our flush reference for the Hyundai Ioniq 9 is 21x9.5J ET38.; our maximum aggressive reference is 22x10J ET35. — beyond that, expect clearance issues against the fender liner without further modification.
Hyundai Ioniq 9 OE Wheel Specs
The Hyundai Ioniq 9 ships from the factory on 5x114.3 bolt pattern wheels with a 67.1mm center bore. The stock wheel size is 20x8.5J ET45, offering a balanced ride that suits most owners without any rubbing or clearance concerns.
Why the factory spec works for most owners:
- Balances ride comfort with steering response and highway efficiency.
- Wide tire and wheel availability at the factory diameter keeps replacement costs low.
- Lower unsprung weight than larger aftermarket wheels helps ride quality and acceleration.
- Guaranteed clearance against brake calipers and suspension components.
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Hyundai Ioniq 9 (2026) we drill the 5x114.3 pattern and cut the centre bore to 67.1mm 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.
Converting these ET figures to backspacing? Use the wheel offset and backspacing calculator.
The figures on this page are part of our open wheel fitment dataset — 10,093 vehicles, free to download, CC BY 4.0.
Offset and Backspacing: Factory Wheel vs Options
Backspacing ≈ width/2 + ET/25.4 + 0.5 in. "Inward" means closer to the suspension; "outward" means closer to the fender lip.
| Setup | Size | ET | Backspacing | Inward vs OE | Outward vs OE |
|---|---|---|---|---|---|
| Factory (OE) | 20x8.5J | ET45 | 6.52 in (166 mm) | — | — |
| Flush | 21x9.5J | ET38 | 6.75 in (171 mm) | +6 mm | +20 mm |
| Maximum | 22x10J | ET35 | 6.88 in (175 mm) | +9 mm | +29 mm |
Vehicles With the Same Hub as the Hyundai Ioniq 9 (5x114.3, 67.1 mm Bore)
In our database, 456 other vehicle entries from 30 makes use exactly the same 5x114.3 bolt pattern and 67.1 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); 35.2% of those also use a 67.1 mm center bore.
Hub-Centric Rings for a 67.1 mm Center Bore
A wheel with a center bore larger than 67.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 70.1 mm | 70.1 → 67.1 mm |
| 70.5 mm | 70.5 → 67.1 mm |
| 71.6 mm | 71.6 → 67.1 mm |
| 72.6 mm | 72.6 → 67.1 mm |
| 73.1 mm | 73.1 → 67.1 mm |
ANKUSI forged wheels are bored to exactly 67.1 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the Hyundai Ioniq 9 use?
The 2026 Hyundai Ioniq 9 uses a 5x114.3 bolt pattern.
How many lug bolts does the Hyundai Ioniq 9 use?
The Hyundai Ioniq 9 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 Hyundai Ioniq 9?
The Hyundai Ioniq 9's center bore is 67.1mm. 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 Hyundai Ioniq 9?
Factory wheels on the Hyundai Ioniq 9 are 20x8.5J ET45.
What does a flush wheel fitment look like on the Hyundai Ioniq 9?
For a flush look with minimal to no rubbing, we recommend 21x9.5J at ET38 offset as a starting point on a stock or mildly lowered Hyundai Ioniq 9.
Do I need wheel spacers for my Hyundai Ioniq 9?
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 Hyundai Ioniq 9?
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 6.75" 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 Hyundai Ioniq 9?
The Hyundai Ioniq 9 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.
