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
The Cadillac SRX's factory suspension tuning already accounts for a specific unsprung mass target. Forged construction lets ANKUSI match the factory strength spec while keeping rotational weight down, which is where the real handling benefit comes from on a taller, heavier SUV platform.
The Cadillac SRX runs a 6x120 bolt pattern, 66.9mm center bore, and a 18x8.0J, front and rear, wheel from the factory. Our Flush Fitment reference is 20x9.0J ET40, which tucks the tire under the fender lip on a stock-height Cadillac SRX. Our Maximum Aggressive reference is 22x9.5J ET35 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Cadillac SRX OE Wheel Specs
The 2010 Cadillac SRX (SUV) uses a 6x120 bolt pattern with a 66.9mm center bore. Factory wheels are 18x8.0J 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 Cadillac SRX (2010) we drill the 6x120 pattern and cut the centre bore to 66.9mm 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: 18x8.0J ET53 → ~6.59″ backspacing
- Flush: 20x9.0J ET40 → ~6.57″ backspacing
- Max: 22x9.5J ET35 → ~6.63″ 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 Cadillac spec, or want a wheel built to a custom offset for your Cadillac SRX? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Cadillac SRX: Specs by Model Year
Vehicles With the Same Hub as the Cadillac SRX (6x120, 66.9 mm Bore)
In our database, 31 other vehicle entries from 5 makes use exactly the same 6x120 bolt pattern and 66.9 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.
6x120 is used by 0.5% of the vehicle pages in our English fitment guide (34 of 6,503); 97.1% of those also use a 66.9 mm center bore.
Hub-Centric Rings for a 66.9 mm Center Bore
A wheel with a center bore larger than 66.9 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 67.1 mm | 67.1 → 66.9 mm |
| 70.1 mm | 70.1 → 66.9 mm |
| 70.5 mm | 70.5 → 66.9 mm |
| 71.6 mm | 71.6 → 66.9 mm |
| 73.1 mm | 73.1 → 66.9 mm |
ANKUSI forged wheels are bored to exactly 66.9 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the Cadillac SRX use?
The 2010 Cadillac SRX uses a 6x120 bolt pattern.
How many lug bolts does the Cadillac SRX use?
The Cadillac SRX uses a 6-lug bolt pattern (6x120), so you need a 6-lug forged wheel to bolt straight on.
What is the center bore size on the Cadillac SRX?
The Cadillac SRX's center bore is 66.9mm. 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 Cadillac SRX?
Factory wheels on the Cadillac SRX are 18x8.0J F/R.
What is the biggest wheel size I can fit on my Cadillac SRX without rubbing?
The most aggressive fitment we recommend without fender work is 22x9.5J at ET35 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 Cadillac SRX?
For a flush look with minimal to no rubbing, we recommend 20x9.0J at ET40 offset as a starting point on a stock or mildly lowered Cadillac SRX.
Do I need wheel spacers for my Cadillac SRX?
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 Cadillac SRX?
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 6.57" 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 Cadillac SRX?
The Cadillac SRX 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.
