2014 Cadillac CTS-V Wheel Interchange

2014 Cadillac CTS-V Wheel Interchange, Sizes, and Fitment Guide | wheelinterchange.com

Known OEM Fitment For 2014 Cadillac CTS-V

The values below reflect known factory specifications for at least one 2014 Cadillac CTS-V configuration. Some trims or body styles may use different front and rear sizes. If a value is not listed or your vehicle differs, use the on-page calculator and confirm against your owner’s manual, VIN-specific OEM data, or a dealer parts department.

Notes:

• Some 2014 CTS-V models may use staggered wheels and tires. If your car has different front and rear sizes, verify each axle separately using the calculator and OEM sources.
• The CTS-V uses large performance brakes. Always check barrel and spoke clearance before driving on any new wheel.
• If aftermarket wheels have a larger center bore than 67.0 mm, use hub-centric rings sized to 67.0 mm at the hub.

How To Use The Wheel Interchange Calculator

The calculator compares “Wheels from (donor vehicle)” against “Installed on (your vehicle).” It also lets you test a custom wheel and tire size. Follow these steps:

• Set “Installed on (your vehicle)” to 2014 Cadillac CTS-V and confirm the baseline values shown above.
• To compare a donor wheel from another vehicle, select it under “Wheels from (donor vehicle).” Verify that the bolt pattern is 5x120 and the center bore is at least 67.0 mm. If the donor center bore is smaller than 67.0 mm, the wheel will not seat without machining.
• Use “Custom wheel size” to input any aftermarket rim diameter, width, and offset you want to test. The calculator will show inner clearance and outer poke changes versus your CTS-V baseline.
• Use “Custom tire size” to enter section width and aspect ratio. When you change rim diameter, the tire diameter in the comparison updates so you can judge speedometer error and fender clearance.
• Aim to keep overall tire diameter close to stock for accurate speedometer and proper ABS and traction control function. Many stick within about 2 to 3 percent, but always verify real clearance on your car.

Fitment Checklist Before You Buy

• Bolt pattern: Must be 5x120.
• Center bore: Wheel must be 67.0 mm or larger. Use rings if larger. Do not use a smaller bore.
• Thread size: M14 x 1.5. Match lug nuts or bolts to the wheel’s seat type and your hardware.
• Offset and width: Verify inner clearance to suspension and brake calipers, and outer clearance to fenders. Use the calculator for changes from the OEM 19x9 ET51 baseline.
• Brake clearance: The CTS-V’s large calipers often require specific spoke shapes. Test-fit one front wheel before mounting tires.
• Tire diameter: Keep overall diameter close to stock to avoid rubbing and speedometer error.
• Load and speed ratings: Tires and wheels must meet or exceed OEM load and speed ratings.
• TPMS: Reuse compatible sensors or install new ones. Frequency and programming can vary by market and production date. Confirm by VIN or with a GM dealer.
• Hardware: Ensure proper lug nut seat type for your wheels. Conical, ball, and mag seats are not interchangeable.
• Spacers or adapters: If used, they must be high quality and hub centric for 67.0 mm. Ensure proper thread engagement. A common guideline is engagement at least equal to the stud diameter.

Plus Sizing And Common Upgrades

Plus sizing changes wheel diameter and width to improve appearance or performance. The CTS-V can be sensitive to offset, width, and brake clearance, so verify everything with the calculator and a physical test-fit. Do not assume any listed size will fit all trims.

• Maintain overall tire diameter close to stock. Many aim for about 2 to 3 percent variance or less. Use the calculator to see speedometer change.
• Width changes affect clearance. Increasing wheel width by 1.0 inch moves each bead about 0.5 inch outward and 0.5 inch inward before offset changes are considered.
• Offset changes move the whole wheel. Lower ET pushes the wheel outward. Higher ET pulls it inward. Each 5 mm of offset change shifts the wheel by about 5 mm.
• Staggered setups: Some CTS-V configurations use wider rears. If your car is staggered, check front and rear sizes separately and keep tire diameters compatible with stability control.
• Aftermarket BBK and barrel shape: The CTS-V’s factory brakes are already large. Many aftermarket wheels clear by spoke design rather than diameter alone. Always check a template or perform a test-fit.

Installation Tips

• Test-fit wheels on the front axle first to confirm caliper clearance and hub seating. Spin by hand to verify no contact.
• Clean the hub face and the wheel mounting pad to remove rust and debris. A clean, flat interface prevents vibration.
• If your aftermarket wheels have a larger center bore, install proper hub-centric rings to 67.0 mm to maintain concentricity.
• Use the correct lug nuts or bolts for the wheel’s seat type. Do not mix seat styles.
• Tighten lugs in a star pattern in stages. Use a calibrated torque wrench and follow the factory torque specification and lubrication guidance in the owner’s manual or service information.
• Re-torque after 25 to 50 miles of driving on new wheels.
• TPMS: Transfer or install compatible sensors. Perform the GM relearn procedure after installation.

FAQs

• Do all 2014 CTS-V models use the same wheel and tire sizes?

  Not always. Some vehicles use staggered front and rear sizes. Use the calculator with your VIN or door-jamb placard values and confirm with OEM sources.

• Is 5x120 the same as 5x4.75?

  No. 5x120 is 120.0 mm PCD. 5x4.75 is approximately 120.65 mm. Do not mix them. Use only 5x120 wheels.

• What center bore do I need?

  The CTS-V hub is 67.0 mm. Wheels must have a center bore of 67.0 mm or larger. If larger, use hub-centric rings to step down to 67.0 mm. A smaller bore will not fit.

• What lug nuts should I use with aftermarket wheels?

  Match the thread size (M14 x 1.5) and the seat type required by the wheel. Common seat types are conical, ball, or mag. Using the wrong seat type can cause loosening or damage.

• How much offset change is safe?

  There is no single number that works for all wheels and tires. Use the calculator to see inner and outer changes from the OEM 19x9 ET51 baseline, then verify caliper, suspension, and fender clearance on your car.

• Can I run spacers on a CTS-V?

  Quality hub-centric spacers can work when needed for clearance. Ensure the spacer maintains a 67.0 mm hub-centric interface and that you have adequate thread engagement. A common guideline is engagement at least equal to the stud diameter.

• Will my speedometer be accurate if I change tire size?

  Only if the overall tire diameter stays close to stock. Use the calculator to compare diameters and aim for minimal variance, then verify in real-world driving.

• Do I need to reprogram TPMS after wheel swaps?

  Yes. When sensors are moved or replaced, perform a relearn. Sensor type and frequency can vary, so confirm compatibility by VIN or with a GM dealer.
