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
Payload and towing figures on a truck are engineered around a specific unsprung mass budget at each corner. Forging lets ANKUSI hit the factory strength rating for the Chevrolet Colorado ZR2 Bison at a lower rotational weight than an equivalent cast wheel, which is the more meaningful upgrade on a work-capable platform than diameter alone.
The Chevrolet Colorado ZR2 Bison runs a 6x120 bolt pattern, 66.9mm 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 Bison. 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 Bison OE Wheel Specs
The 2019 Chevrolet Colorado ZR2 Bison (Truck) uses a 6x120 bolt pattern with a 66.9mm 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 Bison.
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.

Decision Guide
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.
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 Bison? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.

Wheel Installation Reference: Torque, Thread & TPMS
Thread & Fastener: M12x1.5, conical-seat lug nut.
Factory Torque Spec: 136 Nm (100 ft-lb). Covers most Chevrolet passenger cars and crossovers on M12 studs.
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.
