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
On a truck platform, wheel weight sits right at the unsprung mass budget the suspension engineers already spent on payload and towing capacity. A forged wheel keeps that budget intact — same strength, less rotational inertia — instead of eating into the margin the way a cheap cast aftermarket wheel can.
The Chevrolet Colorado ZR2 runs a 6x139.7 bolt pattern, 78.1mm center bore, and a 17x8.0J, front and rear, wheel from the factory. Our Flush Fitment reference is 17x8.5J ET15, which tucks the tire under the fender lip on a stock-height Chevrolet Colorado ZR2. Our Maximum Aggressive reference is 17x9.0J ET0 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Chevrolet Colorado ZR2 OE Wheel Specs
The 2023 Chevrolet Colorado ZR2 (Truck) uses a 6x139.7 bolt pattern with a 78.1mm center bore. Factory wheels are 17x8.0J F/R.
Why the factory spec works for most owners:
- Supports higher payload and towing capacity
- Preserves ground clearance for towing, hauling and light off-road use
- Matches tire sizing commonly available for this class of vehicle
- Maintains clearance for the factory suspension and brake package
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Chevrolet Colorado ZR2 (2023) we drill the 6x139.7 pattern and cut the centre bore to 78.1mm 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.

A Note on Clearance
Final clearance depends on the exact tire model, suspension height, brake package, alignment and vehicle tolerances. A physical test fit is recommended before production.
Want to check a different width or offset before you order? Use our Offset & Backspacing Calculator to solve the numbers yourself, or looking for your exact Chevrolet spec, or want a wheel built to a custom offset for your Chevrolet Colorado ZR2? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Chevrolet Colorado ZR2: Specs by Model Year
| Year | Bolt pattern | Center bore | Factory wheel |
|---|---|---|---|
| 2017 | 6x120 | 66.9 mm | 17x8J ET33 |
| 2021 | 6x120 | 66.9 mm | 17x8J ET33 |
| 2023 | 6x139.7 | 78.1 mm | 17x8J ET33 |
Check the model year before ordering: the specs change — bolt pattern 6x120 → 6x139.7 from 2023; center bore 66.9 mm → 78.1 mm from 2023.
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) | 17x8J | ET33 | 5.80 in (147 mm) | — | — |
| Flush | 17x8.5J | ET15 | 5.34 in (136 mm) | −12 mm | +24 mm |
| Maximum | 17x9J | ET0 | 5.00 in (127 mm) | −20 mm | +46 mm |
Vehicles With the Same Hub as the Chevrolet Colorado ZR2 (6x139.7, 78.1 mm Bore)
In our database, 79 other vehicle entries from 6 makes use exactly the same 6x139.7 bolt pattern and 78.1 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.
6x139.7 is used by 4.0% of the vehicle pages in our English fitment guide (258 of 6,503); 31.0% of those also use a 78.1 mm center bore.
Hub-Centric Rings for a 78.1 mm Center Bore
A wheel with a center bore larger than 78.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 84.1 mm | 84.1 → 78.1 mm |
| 93.1 mm | 93.1 → 78.1 mm |
| 100.1 mm | 100.1 → 78.1 mm |
| 106.1 mm | 106.1 → 78.1 mm |
ANKUSI forged wheels are bored to exactly 78.1 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the Chevrolet Colorado ZR2 use?
The 2023 Chevrolet Colorado ZR2 uses a 6x139.7 bolt pattern.
How many lug bolts does the Chevrolet Colorado ZR2 use?
The Chevrolet Colorado ZR2 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 Chevrolet Colorado ZR2?
The Chevrolet Colorado ZR2's center bore is 78.1mm. 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 Chevrolet Colorado ZR2?
Factory wheels on the Chevrolet Colorado ZR2 are 17x8.0J F/R.
What is the biggest wheel size I can fit on my Chevrolet Colorado ZR2 without rubbing?
The most aggressive fitment we recommend without fender work is 17x9.0J at ET0 offset. Going beyond this typically causes rubbing under compression unless you roll the fenders or add camber correction.
What does a flush wheel fitment look like on the Chevrolet Colorado ZR2?
For a flush look with minimal to no rubbing, we recommend 17x8.5J at ET15 offset as a starting point on a stock or mildly lowered Chevrolet Colorado ZR2.
Do I need wheel spacers for my Chevrolet Colorado ZR2?
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 Chevrolet Colorado ZR2?
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 5.34" 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 Chevrolet Colorado ZR2?
The Chevrolet Colorado ZR2 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: M12x1.5 or M14x1.5, conical-seat lug nut.
Factory Torque Spec: 179-190 Nm (132-140 ft-lb). Shared Silverado 1500/Colorado bolt pattern; exact thread and torque depend on generation, confirm for your specific model year.
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.
