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
Off-road platforms put real, repeated impact loads through the wheel that street-only vehicles never see, so the factory strength margin on the Hyundai i800 isn't a formality — it's load-bearing in a literal sense. Forging matches that margin at a lower rotational weight than an equivalent cast wheel, which matters both on the trail and on the highway miles between trailheads.
The Hyundai i800 ships from the factory on a 6x139.7 bolt pattern with a 92.3mm center bore and a 16x6.5J ET45 wheel. Our flush reference for the Hyundai i800 is 18x8J ET35.; our maximum aggressive reference is 19x8.5J ET30. — beyond that, expect clearance issues against the fender liner without further modification.
Hyundai i800 OE Wheel Specs
The Hyundai i800 ships from the factory on 6x139.7 bolt pattern wheels with a 92.3mm center bore. The stock wheel size is 16x6.5J 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 i800 (2008) we drill the 6x139.7 pattern and cut the centre bore to 92.3mm 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.

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) | 16x6.5J | ET45 | 5.52 in (140 mm) | — | — |
| Flush | 18x8J | ET35 | 5.88 in (149 mm) | +9 mm | +29 mm |
| Maximum | 19x8.5J | ET30 | 5.93 in (151 mm) | +10 mm | +40 mm |
Vehicles With the Same Hub as the Hyundai i800 (6x139.7, 92.3 mm Bore)
In our database, 2 other vehicle entries from 2 makes use exactly the same 6x139.7 bolt pattern and 92.3 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); 1.2% of those also use a 92.3 mm center bore.
Hub-Centric Rings for a 92.3 mm Center Bore
A wheel with a center bore larger than 92.3 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 93.1 mm | 93.1 → 92.3 mm |
| 100.1 mm | 100.1 → 92.3 mm |
| 106.1 mm | 106.1 → 92.3 mm |
| 108.1 mm | 108.1 → 92.3 mm |
ANKUSI forged wheels are bored to exactly 92.3 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the Hyundai i800 use?
The 2008 Hyundai i800 uses a 6x139.7 bolt pattern.
How many lug bolts does the Hyundai i800 use?
The Hyundai i800 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 Hyundai i800?
The Hyundai i800's center bore is 92.3mm. 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 i800?
Factory wheels on the Hyundai i800 are 16x6.5J ET45.
What does a flush wheel fitment look like on the Hyundai i800?
For a flush look with minimal to no rubbing, we recommend 18x8J at ET35 offset as a starting point on a stock or mildly lowered Hyundai i800.
Do I need wheel spacers for my Hyundai i800?
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 i800?
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 5.88" 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 i800?
The Hyundai i800 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.
