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
Because an SUV's center of gravity is already higher than a sedan's, anything added at the corners — including wheel weight — has an outsized effect on handling balance. A forged wheel lets us hit the visual stance owners want without adding the rotational mass a cast wheel of the same strength would carry.
The Hummer H2 SUV ships from the factory on a 8x165.1 bolt pattern with a 116.7mm center bore and a 17x8.5J ET18 wheel. Our flush reference for the Hummer H2 SUV is 20x10J ET-12.; our maximum aggressive reference is 22x12J ET-44. — beyond that, expect clearance issues against the fender liner without further modification.
Hummer H2 SUV OE Wheel Specs
The Hummer H2 SUV ships from the factory on 8x165.1 bolt pattern wheels with a 116.7mm center bore. The stock wheel size is 17x8.5J ET18, offering a balanced ride that suits most owners without any rubbing or clearance concerns.
Why the factory spec works for most owners:
- Balances ride comfort with steering response and highway efficiency.
- Wide tire and wheel availability at the factory diameter keeps replacement costs low.
- Lower unsprung weight than larger aftermarket wheels helps ride quality and acceleration.
- Guaranteed clearance against brake calipers and suspension components.
Flush Fitment
For a flush look without any body modification, most Hummer H2 SUV owners run 20x10J ET-12. This setup tucks the wheel face closer to the fender lip while staying within safe load and clearance limits.
