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 CTS's factory wheel spec reflects a deliberate balance between comfort, steering feel and durability that the engineering team tuned for. Forging lets ANKUSI match that same strength target while trimming rotational mass — the part of a wheel upgrade that actually changes how the car drives, not just how it looks.
The Cadillac CTS runs a 5x115 bolt pattern, 70.3mm center bore, and a 16x7.0J, front and rear, wheel from the factory. Our Flush Fitment reference is 18x8.5J ET40, which tucks the tire under the fender lip on a stock-height Cadillac CTS. Our Maximum Aggressive reference is 19x9.0J ET35 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Cadillac CTS OE Wheel Specs
The 2004 Cadillac CTS (Sedan) uses a 5x115 bolt pattern with a 70.3mm center bore. Factory wheels are 16x7.0J F/R.
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 CTS (2004) we drill the 5x115 pattern and cut the centre bore to 70.3mm 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 18x8.5J ET40 is the recommended starting point on a stock or mildly lowered Cadillac CTS.
Maximum Aggressive Fitment
F/R 19x9.0J ET35 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Decision Guide
1
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 Cadillac CTS owners.
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: 16x7.0J ET51 → ~6.01″ backspacing
- Flush: 18x8.5J ET40 → ~6.32″ backspacing
- Max: 19x9.0J ET35 → ~6.38″ 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 CTS? 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 Cadillac CTS (2004)
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 5x115 pattern and the 70.3mm 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 Cadillac orders on this platform land somewhere between the 18x8.5J ET40 flush setup and the 19x9.0J ET35 aggressive setup referenced above.

What bolt pattern (PCD) does the Cadillac CTS use?
The 2004 Cadillac CTS uses a 5x115 bolt pattern.
How many lug bolts does the Cadillac CTS use?
The Cadillac CTS uses a 5-lug bolt pattern (5x115), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Cadillac CTS?
The Cadillac CTS's center bore is 70.3mm. 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 CTS?
Factory wheels on the Cadillac CTS are 16x7.0J F/R.
What is the biggest wheel size I can fit on my Cadillac CTS without rubbing?
The most aggressive fitment we recommend without fender work is 19x9.0J 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 CTS?
For a flush look with minimal to no rubbing, we recommend 18x8.5J at ET40 offset as a starting point on a stock or mildly lowered Cadillac CTS.
Do I need wheel spacers for my Cadillac CTS?
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 CTS?
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 6.32" 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 CTS?
The Cadillac CTS 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.
Vehicles With the Same Hub as the Cadillac CTS (5x115, 70.3 mm Bore)
In our database, 134 other vehicle entries from 9 makes use exactly the same 5x115 bolt pattern and 70.3 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.
5x115 is used by 3.3% of the vehicle entries in our database (209 of 6,396); 65.1% of those also use a 70.3 mm center bore.
Cadillac CTS: Specs by Model Year
Hub-Centric Rings for a 70.3 mm Center Bore
A wheel with a center bore larger than 70.3 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 70.5 mm | 70.5 → 70.3 mm |
| 71.6 mm | 71.6 → 70.3 mm |
| 72.6 mm | 72.6 → 70.3 mm |
| 73.1 mm | 73.1 → 70.3 mm |
ANKUSI forged wheels are bored to exactly 70.3 mm for this vehicle, so no ring is needed.
