Wheel Size & Offset at a Glance
| Configuration | Wheel Size & Offset |
|---|---|

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 Silverado HD 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 Silverado HD runs a 8x180 bolt pattern, 124.1mm center bore, and a 18x8.0J, front and rear, wheel from the factory. Our Flush Fitment reference is 20x9.5J ET25, which tucks the tire under the fender lip on a stock-height Chevrolet Silverado HD. Our Maximum Aggressive reference is 22x10.0J ET18 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Chevrolet Silverado HD OE Wheel Specs
The 2011 Chevrolet Silverado HD (Truck) uses a 8x180 bolt pattern with a 124.1mm center bore. Factory wheels are 18x8.0J 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 20x9.5J ET25 is a commonly used starting point — clearance must be verified on a stock or mildly lowered Chevrolet Silverado HD.
Maximum Aggressive Fitment
F/R 22x10.0J ET18 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

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: 22x10.0J ET18
Cost: ~$5,500
Outcome: Maximum visual impact; daily comfort and fuel economy are heavily compromised, physical test fit required before production.
Decision Guide
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: 18x8.0J ET44 → ~6.23″ backspacing
- Flush: 20x9.5J ET25 → ~6.23″ backspacing
- Max: 22x10.0J ET18 → ~6.21″ 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 Silverado HD? 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: 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.
