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

Flush Fitment

For a flush look, F/R 17x8.5J ET15 is a commonly used starting point — clearance must be verified on a stock or mildly lowered Chevrolet Colorado ZR2.

Maximum Aggressive Fitment

F/R 17x9.0J ET0 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Real-World Reference Cases

The examples below are compiled from typical ANKUSI customer configurations and are labeled as reference cases, not individually verified real-world builds.

Case 1: Daily Driver (Factory-Style)

Profile: Everyday driving, prioritizes comfort and low running cost.

Setup: 17x8.0J ET33

Cost: ~$620

Outcome: Minimal visual change, ride and fuel economy essentially unaffected.

Case 2: Balanced Enthusiast (Balanced / Flush Fit)

Profile: Wants a sportier stance without sacrificing daily usability.

Setup: 17x8.5J ET15

Cost: ~$3,000

Outcome: Noticeable visual upgrade, fuel economy drop within the expected range.

Case 3: Show Build (Max Aggressive)

Profile: Built primarily for shows or occasional track/show use.

Setup: 17x9.0J ET0

Cost: ~$5,500

Outcome: Maximum visual impact; daily comfort and fuel economy are heavily compromised, physical test fit required before production.

Decision Guide

1
What's your primary use? Daily commuting → Tier A/B. Weekend street driving → Tier B/C. Show or occasional track use → Tier D/E.
2
What's your budget? Under $800 → Tier A. $800-3,400 → Tier B/C. $3,400+ → Tier D/E.
3
How much does fuel economy matter? Very important → Tier A. Somewhat important → Tier B/C. Not a priority → Tier D/E.
4
Still unsure? Tier C (Balanced / Flush Fit) is the default choice for most Chevrolet Colorado ZR2 owners.

Offset & Backspacing Reference

Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):

  • OE: 17x8.0J ET33 → ~5.8″ backspacing
  • Flush: 17x8.5J ET15 → ~5.34″ backspacing
  • Max: 17x9.0J ET0 → ~5″ backspacing

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.

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.
