Recorded OEM specifications for the 2017 Cadillac CTS, donor years with overlapping ranges, and a calculator to compare a selected wheel. Range overlap is not a guaranteed fit.
Baseline mounting dimensions used for interchange decisions.
Multiple OEM configurations exist for this vehicle. Fitment can vary by trim, brakes, and factory wheel package – confirm your exact setup before buying.

These are vehicle-year records whose recorded OEM ranges overlap this 2017 Cadillac CTS. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 39 donor years. Listed 24 eligible overlaps (not all evaluated years are compatible). Showing all listed.
Years grouped because recorded compatibility evidence is equivalent. Each year keeps its own page.
Approximate position vs the mid OEM package: outer change -3.5 mm, inner change 3.5 mm. This uses aggregated width/offset ranges, not a specific wheel.
Recorded vehicle-side thread for the 2017 Cadillac CTS is M14x1.5. This donor year is recorded as M12x1.5. That is the vehicle stud/nut thread, not an intrinsic thread stamped on the wheel. Hardware must match this vehicle’s studs and the selected wheel’s seat and engagement. Existing hardware may be reusable if it already matches. Seat style is not in this dataset, so products are not a verified fit.
Dataset suggestionHub-centric rings ≈ 70.3 → 66.9 mm – not a verified installation requirement.
Hub-centric rings of about 70.3 → 66.9 mm mm may be relevant if the wheel bore is larger than the hub; clearance is not verified. Donor width/offset sits outside the known OEM envelope for this vehicle.
Years grouped because recorded compatibility evidence is equivalent. Each year keeps its own page.
Dataset suggestionWheel spacer ≈ 17.85 mm – not a verified installation requirement.
A spacer of about 17.85 mm is a dataset suggestion only; clearance is not verified. Estimated outer position is about 17.85 mm farther inward than the mid OEM package.

Donor width/offset sits outside the known OEM envelope for this vehicle.
Recorded OEM bolt pattern, center bore, and width/offset ranges overlap. This is not a guarantee that every wheel from the donor year fits this vehicle.

The values below reflect one documented factory configuration. Trim, brake package, and wheel option packages can change specifications. If your CTS differs, use the on-page calculator and confirm with your door-jamb tire placard, the owner’s manual, or a Cadillac dealer by VIN.
| Bolt pattern (studs x PCD) | 5x120 |
| Center bore | 66.9 mm |
| Thread size | M14 x 1.5 |
| Rim diameter | 19 in |
| Rim width | 8.5 in |
| Wheel offset (ET) | 34 mm |
| Backspacing | 5.59 in |
| Tire section width | 245 mm |
| Tire aspect ratio | 45 |
| Tire rim diameter | 17 in |
Notes:
The calculator on this page compares Wheels from (donor vehicle) vs Installed on (your vehicle). It also lets you enter a Custom wheel size and Custom tire size. When you change rim diameter, the tool updates tire diameter in the comparison so you can see overall height differences.
The 2017 CTS was offered with multiple wheel and tire packages. The values listed above show one configuration. If your door placard shows a different baseline, use that as your starting point.
What is the bolt pattern on a 2017 Cadillac CTS?
5x120.
What center bore do I need?
66.9 mm. If your aftermarket wheel has a larger bore, use 66.9 mm ID hub-centric rings. A smaller bore will not fit.
What lug nut thread size does the CTS use?
M14 x 1.5. Match lug seat style to the wheel design and torque to the OEM spec listed in your owner’s manual.
Why do the listed wheel and tire sizes show 19 inch wheels and a 17 inch tire example?
The 2017 CTS was offered with multiple packages. The values above reflect known data points from different trims. Confirm your exact OEM size using the tire placard and compare options with the calculator.
Will different offsets fit my CTS?
Possibly. The OEM reference here is ET 34 mm. Use the calculator to see inner clearance to suspension and outer poke to fenders, then test-fit before driving.
Can I run spacers?
Use only quality hub-centric spacers and ensure proper thread engagement or use extended hardware. Recheck torque after installation. Verify legality and warranty implications.
How do I keep overall tire diameter close to stock when plus sizing?
As you increase rim diameter, reduce tire aspect ratio. Use the calculator to keep overall diameter within a small variance and verify clearance at full lock and compression.
How do I verify the correct torque spec?
Check the owner’s manual or OEM service information for your exact trim and wheel option. Do not guess.
Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:
A normal wheel spacer does not change bolt pattern. Hub rings cannot enlarge a wheel bore that is smaller than the hub. Brake clearance and tire package fitment still require vehicle-specific checks when not confirmed in the dataset.
