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 Extended Cab 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 Extended Cab runs a 6x139.7 bolt pattern, 78.1mm center bore, and a 17x7.5J, front and rear, wheel from the factory. Our Flush Fitment reference is 20x9.0J ET20, which tucks the tire under the fender lip on a stock-height Chevrolet Silverado Extended Cab. Our Maximum Aggressive reference is 22x10.0J ET15 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Chevrolet Silverado Extended Cab OE Wheel Specs
The 2007 Chevrolet Silverado Extended Cab (Pickup) uses a 6x139.7 bolt pattern with a 78.1mm center bore. Factory wheels are 17x7.5J F/R.
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
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Chevrolet Silverado Extended Cab (2007) we drill the 6x139.7 pattern and cut the centre bore to 78.1mm 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.

Flush Fitment
For a flush look with minimal rubbing, F/R 20x9.0J ET20 is the recommended starting point on a stock or mildly lowered Chevrolet Silverado Extended Cab.
Maximum Aggressive Fitment
F/R 22x10.0J ET15 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

What's your primary use? Daily commuting → Tier A/B. Weekend street driving → Tier B/C. Show or occasional track use → Tier D/E.
2
What's your budget? Under $800 → Tier A. $800-3,400 → Tier B/C. $3,400+ → Tier D/E.
3
How much does fuel economy matter? Very important → Tier A. Somewhat important → Tier B/C. Not a priority → Tier D/E.
4
Still unsure? Tier C (Balanced / Flush Fit) is the default choice for most Chevrolet Silverado Extended Cab owners.
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: 17x7.5J ET31 → ~5.47″ backspacing
- Flush: 20x9.0J ET20 → ~5.79″ backspacing
- Max: 22x10.0J ET15 → ~6.09″ 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 Extended Cab? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Custom Forged Wheels for the Chevrolet Silverado Extended Cab (2007)
Everything above is reference data. If you want wheels actually built to it, that is what ANKUSI does: we are a forged wheel factory in Guangzhou, China, IATF 16949 and ISO 9001 certified, forging on our own 10,000-ton press and producing over 120,000 wheels a year. Forging blank, CNC machining, finishing, coating and inspection all happen in the same building — nothing is subcontracted and nothing is relabelled from another manufacturer.
Every set is cut to order, so the 6x139.7 pattern and the 78.1mm centre bore are machined for this car specifically rather than shimmed with adaptor rings. Diameter, width, offset, concavity, monoblock or multi-piece construction and the finish are all yours to choose — most Chevrolet orders on this platform land somewhere between the 20x9.0J ET20 flush setup and the 22x10.0J ET15 aggressive setup referenced above.

What bolt pattern (PCD) does the Chevrolet Silverado Extended Cab use?
The 2007 Chevrolet Silverado Extended Cab uses a 6x139.7 bolt pattern.
How many lug bolts does the Chevrolet Silverado Extended Cab use?
The Chevrolet Silverado Extended Cab uses a 6-lug bolt pattern (6x139.7), so you need a 6-lug forged wheel to bolt straight on.
What is the center bore size on the Chevrolet Silverado Extended Cab?
The Chevrolet Silverado Extended Cab's center bore is 78.1mm. 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 Extended Cab?
Factory wheels on the Chevrolet Silverado Extended Cab are 17x7.5J F/R.
What is the biggest wheel size I can fit on my Chevrolet Silverado Extended Cab without rubbing?
The most aggressive fitment we recommend without fender work is 22x10.0J at ET15 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 Extended Cab?
For a flush look with minimal to no rubbing, we recommend 20x9.0J at ET20 offset as a starting point on a stock or mildly lowered Chevrolet Silverado Extended Cab.
Do I need wheel spacers for my Chevrolet Silverado Extended Cab?
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 Extended Cab?
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 5.79" 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 Extended Cab?
The Chevrolet Silverado Extended Cab 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: M12x1.5 or M14x1.5, conical-seat lug nut.
Factory Torque Spec: 179-190 Nm (132-140 ft-lb). Shared Silverado 1500/Colorado bolt pattern; exact thread and torque depend on generation, confirm for your specific model year.
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.
