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
Trucks live and die on unsprung weight and load capacity — every pound added at the wheel is a pound the suspension has to control over every bump, fully loaded or not. Forging the wheel instead of casting it lets us hold the factory load rating while cutting rotational mass, which pays off directly in ride quality and steering response on a vehicle that spends real time towing or hauling.
The Chevrolet SSR Indy 500 Pace Vehicle runs a 6x127 bolt pattern, 78.1mm center bore, and a F: 19x8.0J wheel from the factory. Our Flush Fitment reference is F 20x9.0J ET35 / R 22x11.0J ET35, which tucks the tire under the fender lip on a stock-height Chevrolet SSR Indy 500 Pace Vehicle. Our Maximum Aggressive reference is F 21x9.5J ET30 / R 22x11.5J ET30 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Chevrolet SSR Indy 500 Pace Vehicle OE Wheel Specs
The 2003 Chevrolet SSR Indy 500 Pace Vehicle (Truck) uses a 6x127 bolt pattern with a 78.1mm center bore. Factory wheels are F: 19x8.0J R: 20x10.0J.
Why the factory spec works for most owners:
- Keeps the factory ride quality and noise levels intact
- A common fitment for this class, so replacement tires are easy to source
- Preserves clearance around the OE brakes and suspension geometry
- Delivers predictable, easy-to-live-with handling for daily use
Flush Fitment
For a flush look with minimal rubbing, F 20x9.0J ET35 / R 22x11.0J ET35 is the recommended starting point on a stock or mildly lowered Chevrolet SSR Indy 500 Pace Vehicle.
Maximum Aggressive Fitment
F 21x9.5J ET30 / R 22x11.5J ET30 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: F 19x8.0J ET46 → ~6.31″ F backspacing, R 20x10.0J ET46 → ~7.31″ R backspacing
- Flush: F 20x9.0J ET35 → ~6.38″ F backspacing, R 22x11.0J ET35 → ~7.38″ R backspacing
- Max: F 21x9.5J ET30 → ~6.43″ F backspacing, R 22x11.5J ET30 → ~7.43″ R 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 SSR Indy 500 Pace Vehicle? 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: Vehicles built before the 2008 model year were not federally required to carry factory TPMS in the US, though many manufacturers adopted it earlier; verify whether your specific build has TPMS before ordering sensor-compatible wheels.
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.
