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
A sedan's wheel spec is a balance point the factory tuned between ride comfort, steering feel, and everyday durability. Forging lets us hold that same structural margin while cutting rotational mass, which is where most of the real-world benefit — quicker steering response, marginally better ride — actually comes from.
The Cadillac CT5-V Blackwing runs a 5x120 bolt pattern, 66.9mm center bore, and a F: 19x10.0J wheel from the factory. Our Flush Fitment reference is F 19x10.5J ET25 / R 19x11.5J ET40, which tucks the tire under the fender lip on a stock-height Cadillac CT5-V Blackwing. Our Maximum Aggressive reference is F 20x10.5J ET22 / R 20x12.0J ET35 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Cadillac CT5-V Blackwing OE Wheel Specs
The 2025 Cadillac CT5-V Blackwing (Sedan) uses a 5x120 bolt pattern with a 66.9mm center bore. Factory wheels are F: 19x10.0J R: 19x11.0J.
Why the factory spec works for most owners:
- Balances ride comfort with everyday drivability
- A commonly used size for this vehicle class, supporting parts and tire availability
- Maintains clearance for the factory suspension and brake components
- Provides stable, predictable handling across normal driving conditions
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Cadillac CT5-V Blackwing (2025) we drill the 5x120 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.
The figures on this page are part of our open wheel fitment dataset — 10,093 vehicles, free to download, CC BY 4.0.
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: F 19x10.0J ET32 → ~6.76″ F backspacing, R 19x11.0J ET45 → ~7.77″ R backspacing
- Flush: F 19x10.5J ET25 → ~6.73″ F backspacing, R 19x11.5J ET40 → ~7.82″ R backspacing
- Max: F 20x10.5J ET22 → ~6.62″ F backspacing, R 20x12.0J ET35 → ~7.88″ 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 Cadillac spec, or want a wheel built to a custom offset for your Cadillac CT5-V Blackwing? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Cadillac CT5-V Blackwing: Specs by Model Year
| Year | Bolt pattern | Center bore | Factory wheel |
|---|---|---|---|

Bolt pattern and center bore stay the same across all 2 model years in our database (2022–2025).
Vehicles With the Same Hub as the Cadillac CT5-V Blackwing (5x120, 66.9 mm Bore)
In our database, 161 other vehicle entries from 10 makes use exactly the same 5x120 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.
5x120 is used by 10.3% of the vehicle pages in our English fitment guide (670 of 6,503); 24.2% 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 CT5-V Blackwing use?
The 2025 Cadillac CT5-V Blackwing uses a 5x120 bolt pattern.
How many lug bolts does the Cadillac CT5-V Blackwing use?
The Cadillac CT5-V Blackwing uses a 5-lug bolt pattern (5x120), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Cadillac CT5-V Blackwing?
The Cadillac CT5-V Blackwing'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 CT5-V Blackwing?
Factory wheels on the Cadillac CT5-V Blackwing are F: 19x10.0J R: 19x11.0J.
What is the biggest wheel size I can fit on my Cadillac CT5-V Blackwing without rubbing?
The most aggressive fitment we recommend without fender work is F 20x10.5J ET22 / R 20x12.0J ET35. 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 CT5-V Blackwing?
For a flush look with minimal to no rubbing, we recommend F 19x10.5J ET25 / R 19x11.5J ET40 as a starting point on a stock or mildly lowered Cadillac CT5-V Blackwing.
Do I need wheel spacers for my Cadillac CT5-V Blackwing?
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 CT5-V Blackwing?
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 6.73" backspacing up front and 7.82" in the rear.
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 CT5-V Blackwing?
Yes — the Cadillac CT5-V Blackwing's factory and our recommended flush/max fitments already use staggered sizing (different width front and rear), and ANKUSI can forge matching staggered sets to your target offsets.
