These are vehicle-year records whose recorded OEM ranges overlap this 2014 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 -1.67 mm, inner change -4.68 mm. This uses aggregated width/offset ranges, not a specific wheel.
Recorded vehicle-side thread for the 2014 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; they cannot enlarge a smaller bore. Recorded vehicle-side thread differs (M12x1.5 on the donor year vs M14x1.5 on the target vehicle). Hardware must match the target vehicle’s studs and the selected wheel’s seat. Existing hardware may be reusable if it already matches. Seat style is not confirmed in this dataset. Approximate position vs the mid OEM package: outer change -10.68 mm, inner change 4.33 mm. This uses aggregated width/offset ranges, not a specific wheel.

Center-bore records disagree (donor year-level hub 67 mm vs trim range 66.9–66.9 mm). Unqualified overlap is not claimed until the conflict is resolved. Approximate position vs the mid OEM package: outer change -12.68 mm, inner change 6.33 mm. This uses aggregated width/offset ranges, not a specific wheel.

The following factory specifications are documented for the 2014 Cadillac CTS. Equipment varied by trim and package, so some values may differ on your specific vehicle. Always confirm against your door-jamb tire label, the owner’s manual, or OEM parts data before purchasing wheels or tires.
| Bolt pattern | 5x120 |
| Center bore | 66.9 mm |
| Thread size | M14 x 1.5 |
| Wheel size (one documented configuration) | 19 x 8.5 |
| Wheel offset (ET) | 34 mm |
| Backspacing | 5.59 in |
| Tire size (one documented configuration) | 245/45R17 |
Notes: The presence of both a 19 inch wheel spec and a 245/45R17 tire spec indicates multiple OEM configurations were offered in 2014. Your CTS may differ. Use the on-page calculator to compare what you have to what you plan to install, and verify final sizes with OEM sources.
The calculator lets you compare a donor setup to your CTS and test custom wheel and tire sizes before you buy.
The 2014 CTS was offered with multiple factory wheel and tire sizes. If you upsize the rim diameter, use a lower-profile tire to keep overall diameter close to stock. Small changes in offset move the wheel in or out and can affect fender and suspension clearance. The calculator will show inner clearance and outer poke changes so you can judge what is reasonable for your car. Because trims differ, do not assume another CTS size will fit yours without checking clearances and verifying against OEM data. When in doubt, test fit and inspect at full steering lock and over bumps.
Also useful: floor jack, jack stands, breaker bar, nylon or brass brush, anti-seize for the hub face only, valve cores and caps, and a TPMS programming tool if needed.
What is the bolt pattern for the 2014 Cadillac CTS?
5x120.
What center bore does the CTS use?
66.9 mm. Use hub-centric rings if your wheel’s center bore is larger. A smaller bore will not fit.
What lug nut thread size is correct?
M14 x 1.5. Match the lug seat style to the wheel design.
Why do I see both 19 inch wheels and 245/45R17 tires listed?
Multiple OEM configurations were offered for 2014. Your car may differ by trim or package. Confirm your exact factory size on the door label or with OEM documentation, and use the calculator to compare alternatives.
How close should overall tire diameter be to stock?
Keep it as close as practical. Even small changes affect speedometer, ABS, and stability control. Use the calculator’s diameter and speedometer change readouts to guide your choice.
Will different offsets fit my CTS?
Possibly, but it depends on width, brakes, and suspension clearance. Use the calculator to view inner clearance and outer poke changes, then test fit to confirm caliper and fender clearance.
Do I need new lug nuts for aftermarket wheels?
Often yes, because many aftermarket wheels use a different seat type or use tuner lugs. Ensure M14 x 1.5 thread and the correct seat style for the wheel.
How do I check brake caliper clearance?
Test fit the front wheel, spin it by hand, and inspect spoke and barrel clearance to the caliper and wheel weights. Clearance cannot be guaranteed by measurements alone.
Can I reuse my TPMS sensors?
Usually yes if the sensor type is compatible with the new wheels. Transfer or install compatible sensors and perform any required relearn or programming.
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.
