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 Hummer Humvee Military Vehicle 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 Hummer Humvee Military Vehicle ships from the factory on a 8x165.1 bolt pattern with a, centre bore pending verification and a 16.5x8.25J ET18 wheel. Our flush reference for the Hummer Humvee Military Vehicle is 5x9J ET0.; our maximum aggressive reference is 20x10J ET-12. — beyond that, expect clearance issues against the fender liner without further modification.
Hummer Humvee Military Vehicle OE Wheel Specs
Verification notice (2026-09-19): the centre bore previously listed for this vehicle (122.5 mm) could not be confirmed by two independent references, so it has been withdrawn until verified. The bolt pattern shown has been confirmed.
The Hummer Humvee Military Vehicle ships from the factory on 8x165.1 bolt pattern wheels with a, centre bore pending verification. The stock wheel size is 16.5x8.25J ET18, 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 Hummer Humvee Military Vehicle (2003) we drill the 8x165.1 pattern 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 & Backspacing Reference
Backspacing is calculated as: wheel width (in) / 2 + offset (mm) / 25.4 + 0.5.
- OE 16.5x8.25J ET18: backspacing ≈ 5.33"
- Flush 16.5x9J ET0: backspacing ≈ 5"
- Max 20x10J ET-12: backspacing ≈ 5.03"

Frequently Asked Questions
What bolt pattern (PCD) does the Hummer Humvee Military Vehicle use?
The 2003 Hummer Humvee Military Vehicle uses a 8x165.1 bolt pattern.
How many lug bolts does the Hummer Humvee Military Vehicle use?
The Hummer Humvee Military Vehicle uses a 8-lug bolt pattern (8x165.1), so you need a 8-lug forged wheel to bolt straight on.
What size are the factory (stock) wheels on the Hummer Humvee Military Vehicle?
Factory wheels on the Hummer Humvee Military Vehicle are 16.5x8.25J ET18.
What does a flush wheel fitment look like on the Hummer Humvee Military Vehicle?
For a flush look with minimal to no rubbing, we recommend 16.5x9J at ET0 offset as a starting point on a stock or mildly lowered Hummer Humvee Military Vehicle.
Do I need wheel spacers for my Hummer Humvee Military Vehicle?
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 Hummer Humvee Military Vehicle?
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" 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 Hummer Humvee Military Vehicle?
The Hummer Humvee Military Vehicle 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.
