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 Silverado HD ZR2 Bison runs a 8x180 bolt pattern, 124.1mm center bore, and a 18x8.5J, front and rear, wheel from the factory. Our Flush Fitment reference is 18x9.0J ET18, which tucks the tire under the fender lip on a stock-height Chevrolet Silverado HD ZR2 Bison. Our Maximum Aggressive reference is 20x10.0J ET0 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Chevrolet Silverado HD ZR2 Bison OE Wheel Specs
The 2024 Chevrolet Silverado HD ZR2 Bison (Truck) uses a 8x180 bolt pattern with a 124.1mm center bore. Factory wheels are 18x8.5J F/R.
Why the factory spec works for most owners:
- Balances ride comfort with everyday drivability
- A commonly used size for this vehicle class, supporting parts and tire availability
- Maintains clearance for the factory suspension and brake components
- Provides stable, predictable handling across normal driving conditions
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Chevrolet Silverado HD ZR2 Bison (2024) we drill the 8x180 pattern and cut the centre bore to 124.1mm 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.

Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: 18x8.5J ET44 → ~6.48″ backspacing
- Flush: 18x9.0J ET18 → ~5.71″ backspacing
- Max: 20x10.0J ET0 → ~5.5″ backspacing
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 Silverado HD ZR2 Bison? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Vehicles With the Same Hub as the Chevrolet Silverado HD ZR2 Bison (8x180, 124.1 mm Bore)
In our database, 10 other vehicle entries from 2 makes use exactly the same 8x180 bolt pattern and 124.1 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.
8x180 is used by 0.2% of the vehicle pages in our English fitment guide (11 of 6,503); 100.0% of those also use a 124.1 mm center bore.
Hub-Centric Rings for a 124.1 mm Center Bore
A wheel with a center bore larger than 124.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 130.1 mm | 130.1 → 124.1 mm |
ANKUSI forged wheels are bored to exactly 124.1 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the Chevrolet Silverado HD ZR2 Bison use?
The 2024 Chevrolet Silverado HD ZR2 Bison uses a 8x180 bolt pattern.
How many lug bolts does the Chevrolet Silverado HD ZR2 Bison use?
The Chevrolet Silverado HD ZR2 Bison uses a 8-lug bolt pattern (8x180), so you need a 8-lug forged wheel to bolt straight on.
What is the center bore size on the Chevrolet Silverado HD ZR2 Bison?
The Chevrolet Silverado HD ZR2 Bison's center bore is 124.1mm. 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 Silverado HD ZR2 Bison?
Factory wheels on the Chevrolet Silverado HD ZR2 Bison are 18x8.5J F/R.
What is the biggest wheel size I can fit on my Chevrolet Silverado HD ZR2 Bison without rubbing?
The most aggressive fitment we recommend without fender work is 20x10.0J 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 Silverado HD ZR2 Bison?
For a flush look with minimal to no rubbing, we recommend 18x9.0J at ET18 offset as a starting point on a stock or mildly lowered Chevrolet Silverado HD ZR2 Bison.
Do I need wheel spacers for my Chevrolet Silverado HD ZR2 Bison?
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 Silverado HD ZR2 Bison?
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 5.71" 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 Silverado HD ZR2 Bison?
The Chevrolet Silverado HD ZR2 Bison 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: M14x1.5, conical-seat lug nut.
Factory Torque Spec: 190 Nm (140 ft-lb). Silverado/Sierra HD single-rear-wheel spec on M14x1.5 studs; dual-rear-wheel (dually) trucks may specify up to 165 ft-lb, confirm before installation.
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.
