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 Holden Colorado 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 Holden Colorado ships from the factory on a 6x139.7 bolt pattern with a 100.5mm center bore and a 16x7J ET33 wheel. Our flush reference for the Holden Colorado is 17x8J ET20.; our maximum aggressive reference is 18x8.5J ET15. — beyond that, expect clearance issues against the fender liner without further modification.
Holden Colorado OE Wheel Specs
The Holden Colorado ships from the factory on 6x139.7 bolt pattern wheels with a 100.5mm center bore. The stock wheel size is 16x7J ET33, 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 Holden Colorado (2009) we drill the 6x139.7 pattern and cut the centre bore to 100.5mm 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) | 16x7J | ET33 | 5.30 in (135 mm) | — | — |
| Flush | 17x8J | ET20 | 5.29 in (134 mm) | 0 mm | +26 mm |
| Maximum | 18x8.5J | ET15 | 5.34 in (136 mm) | +1 mm | +37 mm |
Vehicles With the Same Hub as the Holden Colorado (6x139.7, 100.5 mm Bore)
In our database, 1 other Holden entries use exactly the same 6x139.7 bolt pattern and 100.5 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); 0.8% of those also use a 100.5 mm center bore.
Hub-Centric Rings for a 100.5 mm Center Bore
A wheel with a center bore larger than 100.5 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 106.1 mm | 106.1 → 100.5 mm |
| 108.1 mm | 108.1 → 100.5 mm |
| 110.1 mm | 110.1 → 100.5 mm |
| 130.1 mm | 130.1 → 100.5 mm |
ANKUSI forged wheels are bored to exactly 100.5 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the Holden Colorado use?
The 2009 Holden Colorado uses a 6x139.7 bolt pattern.
How many lug bolts does the Holden Colorado use?
The Holden Colorado 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 Holden Colorado?
The Holden Colorado's center bore is 100.5mm. 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 Holden Colorado?
Factory wheels on the Holden Colorado are 16x7J ET33.
What does a flush wheel fitment look like on the Holden Colorado?
For a flush look with minimal to no rubbing, we recommend 17x8J at ET20 offset as a starting point on a stock or mildly lowered Holden Colorado.
Do I need wheel spacers for my Holden Colorado?
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 Holden Colorado?
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 5.29" 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 Holden Colorado?
The Holden Colorado 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.
