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 BMW iX5 Hydrogen Concept ships from the factory on a 5x112 bolt pattern with a 66.6mm center bore and a 20x9J ET35 wheel. Our flush reference for the BMW iX5 Hydrogen Concept is 21x9.5J ET30.; our maximum aggressive reference is 22x10J ET25. — beyond that, expect clearance issues against the fender liner without further modification.
BMW iX5 Hydrogen Concept OE Wheel Specs
The BMW iX5 Hydrogen Concept ships from the factory on 5x112 bolt pattern wheels with a 66.6mm center bore. The stock wheel size is 20x9J ET35, 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 BMW iX5 Hydrogen Concept (2023) we drill the 5x112 pattern and cut the centre bore to 66.6mm 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) | 20x9J | ET35 | 6.38 in (162 mm) | — | — |
| Flush | 21x9.5J | ET30 | 6.43 in (163 mm) | +1 mm | +11 mm |
| Maximum | 22x10J | ET25 | 6.48 in (165 mm) | +3 mm | +23 mm |
Vehicles With the Same Hub as the BMW iX5 Hydrogen Concept (5x112, 66.6 mm Bore)
In our database, 823 other vehicle entries from 21 makes use exactly the same 5x112 bolt pattern and 66.6 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.
5x112 is used by 21.6% of the vehicle pages in our English fitment guide (1,407 of 6,503); 58.6% of those also use a 66.6 mm center bore.
Hub-Centric Rings for a 66.6 mm Center Bore
A wheel with a center bore larger than 66.6 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 67.1 mm | 67.1 → 66.6 mm |
| 70.1 mm | 70.1 → 66.6 mm |
| 70.5 mm | 70.5 → 66.6 mm |
| 71.6 mm | 71.6 → 66.6 mm |
| 73.1 mm | 73.1 → 66.6 mm |
ANKUSI forged wheels are bored to exactly 66.6 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the BMW iX5 Hydrogen Concept use?
The 2023 BMW iX5 Hydrogen Concept uses a 5x112 bolt pattern.
How many lug bolts does the BMW iX5 Hydrogen Concept use?
The BMW iX5 Hydrogen Concept uses a 5-lug bolt pattern (5x112), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the BMW iX5 Hydrogen Concept?
The BMW iX5 Hydrogen Concept's center bore is 66.6mm. 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 BMW iX5 Hydrogen Concept?
Factory wheels on the BMW iX5 Hydrogen Concept are 20x9J ET35.
What does a flush wheel fitment look like on the BMW iX5 Hydrogen Concept?
For a flush look with minimal to no rubbing, we recommend 21x9.5J at ET30 offset as a starting point on a stock or mildly lowered BMW iX5 Hydrogen Concept.
Do I need wheel spacers for my BMW iX5 Hydrogen Concept?
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 BMW iX5 Hydrogen Concept?
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 6.43" 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 BMW iX5 Hydrogen Concept?
The BMW iX5 Hydrogen Concept 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.
Wheel Installation Reference: Torque, Thread & TPMS
Thread & Fastener: M14x1.25, 60-degree conical-seat lug bolt.
Factory Torque Spec: 140 Nm (103 ft-lb). Consistent across modern BMW passenger and X-series models using factory conical-seat bolts.
TPMS: TPMS (Tire Pressure Monitoring System) has been federally mandated on all new light vehicles sold in the US since the 2008 model year. If your wheels use OE-style sensors, have them transferred or cloned to the new wheels at installation.
Tire Pressure: Always set tire pressure to the value on your vehicle's tire placard (driver's doorjamb or glovebox), not the max PSI printed on the tire sidewall — this is trim- and tire-size-specific and stays the same reference point when you switch to a different wheel and tire combination.
Reference data compiled from published OEM service specifications and cross-checked against independent repair sources; always confirm against your owner's manual or door-jamb placard before installation.
