2016 Cadillac CTS Wheel Interchange, Sizes, and Fitment Guide
Known OEM Fitment For 2016 Cadillac CTS
The figures below are known OEM specifications for the 2016 Cadillac CTS. Trims and packages can use different wheel and tire combinations. If a value is missing from your trim or you see conflicting sizes, verify using the on-page calculator and your OEM sources like the door-jamb tire label, owner’s manual, and VIN or RPO code lookup.

Note: The presence of a 19 inch wheel size and a 17 inch tire size indicates multiple factory setups across trims. Use the calculator to confirm your exact baseline by entering the sizes from your CTS, then compare against any wheels you plan to install.
How To Use The Wheel Interchange Calculator
Select “Installed on” and enter your CTS baseline. If your door-jamb label lists a different wheel or tire size than the table above, use the label value as your baseline.
Enter the “Wheels from” donor vehicle or a “Custom wheel size” by setting rim diameter, width, and offset. Add a “Custom tire size” if you plan to change tires as well.
The tool compares inner clearance, outer poke, ride height change, and speedometer difference. When you change rim diameter, the calculator updates tire diameter in the comparison so you can keep overall diameter close to stock.
Aim to keep overall tire diameter within about 2 to 3 percent of your baseline to help maintain ABS, traction control, and speedometer accuracy.
Use the clearance visuals to ensure brake caliper and fender clearance. If inner clearance decreases too much or outer poke increases, adjust offset or width in small steps and recheck.
If your offset or backspacing is unknown, measure your current wheel before removal: place a straightedge across the inboard rim edge and measure to the hub pad for backspacing, then use the calculator to convert to offset.
Fitment Checklist Before You Buy
Bolt pattern must match 5x120. Do not attempt 5x4.75 or 5x114.3 patterns.
Center bore is 66.9 mm at the hub. The wheel must be hub-centric to 66.9 mm or use quality hub-centric rings if the wheel’s bore is larger.
Thread size is M14 x 1.5. Confirm lug nut seat type matches the wheel design. Do not mix conical-seat nuts with ball-seat wheels.
Offset and width must clear struts, control arms, and fenders. Use the calculator to compare inner clearance and outer poke to your baseline.
Overall tire diameter change should typically stay within about 2 to 3 percent of stock. Verify with the calculator’s diameter and speedometer readouts.
Brake clearance. Visually confirm spoke and barrel clearance over calipers, especially with larger brakes.
Load rating. Wheels and tires must meet or exceed your CTS axle and GVWR requirements.
TPMS compatibility. Plan to swap sensors or use compatible replacements and perform relearn per the manual.
Spacers only if necessary. Use hub-centric spacers with proper stud engagement. Recalculate offset and verify fender coverage and bearing load.
Torque fasteners to the factory spec for your trim. If unknown, check your owner’s manual or OEM service information.
Plus Sizing And Common Upgrades
Cadillac offered multiple OEM wheel and tire combinations on the 2016 CTS. If you are moving up or down in wheel diameter, keep these principles in mind and verify every change with the calculator.
Plus sizing method. When increasing wheel diameter, choose a lower tire aspect ratio so overall tire diameter stays close to stock. Example method: for each 1 inch increase in wheel diameter, reduce tire sidewall height to compensate and confirm with the calculator.
Width changes. A wider wheel can improve response but adds outer poke and may reduce inner clearance. Increase width in small steps and use offset adjustments to center the wheel in the well.
Ride and handling. Lower profile tires sharpen steering but transmit more impact and noise. Verify load index and speed rating meet or exceed OEM.
Staggered setups. If you consider a staggered fitment, confirm rotation strategy, tire availability, and ESC or AWD compatibility where applicable.
Installation Tips
Park on level ground, chock wheels, and use a properly rated jack and stands at the factory lift points.
Test fit each wheel without a tire first if possible to verify hub fit, brake clearance, and stud engagement.
Clean hub faces and wheel mounting pads. Remove corrosion so the wheel sits flush. Do not paint or grease the hub face.
Install lug nuts by hand, verify the seat type matches, and snug in a star pattern.
Torque with a calibrated torque wrench to the Cadillac spec for your trim. Recheck torque after 50 to 100 miles.
TPMS. Move or program sensors and perform relearn as described in your owner’s manual.
Avoid lubricant on studs or nuts unless the service manual explicitly allows it. Use only a tiny amount of anti-seize on the hub pilot if corrosion is a known issue and manufacturer permits.
66.9 mm. Use hub-centric wheels or rings that size down to 66.9 mm if the aftermarket wheel bore is larger.
Which lug nuts do I need
Thread size is M14 x 1.5. The seat type must match your wheel design. Many aftermarket wheels use a 60 degree conical seat, but verify visually or with the wheel manufacturer. Do not mix seat types.
Why do I see a 19 inch wheel and a 17 inch tire listed
Different 2016 CTS trims used different OEM wheel and tire packages. Use your door-jamb tire label or owner’s manual to confirm your exact stock size, then enter that as the baseline in the calculator.
What offset should I use
One OEM reference shown here is ET 34 mm for an 8.5 inch wheel. Offsets vary by trim and wheel width. Use the calculator to compare inner clearance and poke versus your verified baseline and choose an offset that maintains safe clearances.
Can I install spacers on my CTS
Only if needed to correct clearance. Use hub-centric spacers with sufficient stud engagement and quality hardware. Recalculate effective offset and confirm fender coverage and bearing load. Check local regulations and consider a professional inspection.
What torque should I use on the lug nuts
Torque specifications can vary by trim and wheel. Refer to your owner’s manual or OEM service information and use a calibrated torque wrench. Re-torque after 50 to 100 miles.
How much diameter change is acceptable when plus sizing
As a general guideline, try to keep overall tire diameter within about 2 to 3 percent of your verified stock size. Use the calculator to check diameter and speedometer impact before buying.
Methodology and sources
Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:
Bolt pattern / PCD
Center bore direction (donor wheel bore must not be smaller than the hub)
Wheel diameter, width, and offset against known OEM ranges
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.
