2017 Cadillac CTS-V Wheel Interchange

2017 Cadillac CTS-V Wheel Fitment Guide | wheelinterchange.com

Known OEM Fitment For 2017 Cadillac CTS-V

The factory specs below reflect verified data for at least one axle on the 2017 Cadillac CTS-V. Some vehicles use a staggered setup where front and rear wheels and tires differ. If a value is not listed for your axle, or if your trim or package may vary, confirm using the on-page calculator and your OEM sources such as the door-jamb tire placard and the owner’s manual.

If your CTS-V has different factory sizing front to rear, enter each axle separately in the calculator and cross-check against your door placard and owner’s manual.

How To Use The Wheel Interchange Calculator

• Select Wheels from to set the donor vehicle whose wheels or sizes you want to compare.
• Select Installed on to set your vehicle as 2017 Cadillac CTS-V.
• Use Custom wheel size to test alternate rim diameter, width, and offset. The tool will instantly recalculate inner clearance to the strut or control arm, and outer poke toward the fender.
• Use Custom tire size to try different tire widths and aspect ratios. When you change rim diameter, the calculator updates overall tire diameter so you can see the speedometer and clearance impact.
• Keep the overall tire diameter change small. A change within about 2 to 3 percent is a common target to preserve gearing, ABS calibration, and fender clearance.
• After you find a setup that works in the calculator, verify physically: check brake caliper clearance, suspension clearance at full lock, and fender clearance under compression.

Fitment Checklist Before You Buy

• Bolt pattern: Must be 5x120.
• Center bore: The wheel must be 66.9 mm or larger. If larger, use quality hub-centric rings to 66.9 mm. A smaller bore will not seat on the hub.
• Offset and width: Use the calculator to ensure inner clearance is safe and outer position does not contact the fender. Large offset changes can affect steering feel and bearing load.
• Brake caliper clearance: CTS-V brakes are performance oriented. Verify spoke and barrel clearance with a template or test fit.
• Tires: Match or exceed OEM load index and speed rating. Use the calculator to keep overall diameter change small.
• Hardware: Confirm seat type of your wheel (conical, ball, or mag) and use matching M14 x 1.5 nuts. Do not mix seat types.
• TPMS: Plan for compatible sensors and relearn procedure after installation.
• Spacers: If required to clear brakes or suspension, use hub-centric spacers matched to 66.9 mm and ensure proper thread engagement. Consider extended studs if needed.
• Rotation and stagger: If your car is staggered, rotation options are limited. Confirm axle-specific sizes before ordering.
• OEM confirmation: Cross-check sizes on your driver door placard and in the owner’s manual before purchase.

Plus Sizing And Common Upgrades

Factory reference on at least one axle is 19 x 9.5 ET 23 with a 265/35R19 tire. Many owners explore plus sizing for appearance or performance, but actual fit varies with wheel design, offset, and tire brand. Follow these guidelines with the calculator and verify on the car:

• Plus one wheel diameter: Increasing rim diameter typically requires a lower tire aspect ratio to keep overall diameter similar. Use the calculator to keep the total diameter change within about 2 to 3 percent.
• Wider wheels and tires: Wider setups can improve grip but reduce inner or outer clearance. Start with small width and offset changes, then check full-lock steering and compression clearance.
• Brake clearance: Larger diameter wheels can improve barrel clearance, but spoke design still matters. Always confirm with a physical template or test fit.
• Winter or track sets: Narrower tires can help winter traction and wet evacuation. Track sets may favor square fitment for rotation. Verify load rating and clearance either way.

Installation Tips

• Work on a cool vehicle parked on level ground. Use a quality floor jack and jack stands at the proper lift points.
• Break lug nuts loose slightly while the car is on the ground. Raise and support the vehicle, then remove nuts fully.
• Clean the hub face and the wheel mounting pad. Remove rust and debris so the wheel seats flat.
• If you use hub-centric rings, ensure they seat fully on the hub and in the wheel.
• Install wheels by hand. Start all nuts by hand to avoid cross-threading. Do not lubricate lug threads unless your OEM service information instructs it.
• Snug in a star pattern, lower the vehicle, then torque in a star pattern to the factory torque listed in your owner’s manual.
• Recheck torque after 50 to 100 miles of driving.
• Perform a TPMS relearn if required so the system recognizes sensor positions.

Tools And Helpful Supplies

• 1/2 inch drive torque wrench
• Low profile floor jack
• Jack stands
• GM compatible TPMS relearn tool
• Impact-rated 6-point sockets and a breaker bar
• Wire brush or hub cleaning tool and a nylon wheel brush
• Plastic hub-centric rings sized to 66.9 mm inner diameter when using wheels with a larger bore
• Painter’s tape or fender covers to protect paint while test fitting

FAQs

• Are all 2017 CTS-V models the same front and rear wheel size?

  Not always. The data listed here applies to at least one axle. Some vehicles use staggered front and rear sizing. Confirm your specific axle sizes using the calculator and your door placard or owner’s manual.

• Will any 5x120 wheel fit my CTS-V?

  No. You must also match or adapt the 66.9 mm center bore, ensure safe offset and width, and verify brake caliper clearance. Use the calculator for clearance estimates and always test fit.

• Do I need hub-centric rings?

  If your aftermarket wheel has a center bore larger than 66.9 mm, use quality hub-centric rings that reduce to 66.9 mm. Wheels with a smaller bore will not fit the hub.

• What is the correct lug nut type for aftermarket wheels?

  The thread is M14 x 1.5, but the seat type depends on the wheel design. Verify whether your wheel requires conical, ball, or mag seat nuts and use only matching hardware.

• What tire diameter change is acceptable when plus sizing?

  Keeping overall tire diameter within about 2 to 3 percent of OEM is a common guideline to maintain clearance and system calibrations. Use the calculator to check diameter and speedometer impact.

• Can I run wheel spacers on a CTS-V?

  If you must use spacers, choose hub-centric spacers matched to 66.9 mm and maintain full lug nut thread engagement. You may need extended studs depending on spacer thickness. Recheck torque after installation.

• What is the wheel torque spec for this car?

  Torque specifications vary by model and wheel. Refer to the owner’s manual or an official service manual for the exact torque and follow it precisely.

Tip: For any values that differ by package or axle, enter your confirmed OEM sizes into the calculator as the baseline, then compare any new wheel and tire option before you buy.
