Known OEM Fitment For 2010 Cadillac CTS-V
The following specs are provided for this model year. If your vehicle has different trim equipment or a staggered setup, values may vary. Always confirm against your owner’s manual, the driver-door jamb label, or a GM dealer by VIN, then validate with the on-page calculator before purchasing.
| Bolt pattern | 5x120 |
| Center bore | 67.0 mm |
| Thread size | M14 x 1.5 |
| OEM rim diameter | 19 in |
| OEM rim width | 9.0 in |
| OEM wheel offset (ET) | 51 mm |
| Backspacing | 6.51 in |
| OEM tire size | 255/40R19 |
Notes:
- Some CTS-V trims may use staggered wheel widths and tire sizes. If your car appears to have wider rear wheels or tires, verify both axles separately.
- If a spec is missing from your documentation, measure directly or consult OEM sources and then model the setup in the calculator.
How To Use The Wheel Interchange Calculator
The calculator on this page is designed to compare a donor setup to your 2010 Cadillac CTS-V, then test custom sizes. Use it to check clearance, poke, inner scrub, and tire diameter differences before you buy.
- Step 1. In Wheels from (donor vehicle), pick the donor car or enter the donor wheel and tire specs.
- Step 2. In Installed on (your vehicle), select 2010 Cadillac CTS-V so the tool uses your hub and chassis reference.
- Step 3. Use Custom wheel size to adjust rim diameter, width, and offset. The tool will recalculate inner clearance to the strut and outer poke vs your fender.
- Step 4. Use Custom tire size to set section width and aspect ratio. When you change rim diameter, the tool updates tire diameter in the comparison so you can keep overall diameter close to OEM.
- Step 5. Check results for:
- Inner clearance change to suspension and brake components.
- Outer position change toward the fender lip.
- Tire diameter difference for speedometer and ABS tolerance.
- Step 6. Repeat for the rear axle if your car is staggered. Save or print the summary before ordering.
Fitment Checklist Before You Buy
- Bolt pattern and hub: Wheel must be 5x120 and either hub-centric at 67.0 mm or paired with quality hub-centric rings to 67.0 mm.
- Brake clearance: Visually confirm spoke-to-caliper and barrel clearance. The CTS-V has large Brembo brakes on many trims.
- Offset and width: Use the calculator to verify inner clearance to strut and outer fender poke. Avoid contact at full lock and full bump.
- Tire overall diameter: Keep total diameter close to stock to protect speedometer, ABS, and traction control. Many installers target within approximately 3 percent of OEM.
- Tire load and speed rating: Equal or higher than OEM ratings. Do not downgrade.
- TPMS: Plan for compatible sensors or a service kit. Confirm relearn procedure for your CTS-V.
- Hardware: Use correct-seat lug nuts for your wheels and the OEM thread M14 x 1.5. Torque to the factory specification from the owner’s manual or service information.
- Staggered setups: If your vehicle is staggered, validate front and rear sizes independently in the calculator.
Plus Sizing And Common Upgrades
Enthusiasts often consider wider wheels or different diameters for performance or appearance. Because actual clearance depends on width, offset, tire profile, and brake package, do not assume another CTS-V owner’s setup will fit your car without verification.
- Plus-one or plus-two diameter: Use the calculator to maintain a similar overall tire diameter when increasing rim size so the speedometer and gearing feel remain predictable.
- Wider tires for traction: Model the new section width and aspect ratio to confirm inner clearance and fender clearance on compression and steering lock.
- Square vs staggered: A square setup simplifies rotation, but check rear fender clearance if downsizing rear width on a staggered vehicle.
- Spacers: Only if needed for brake or strut clearance and only with adequate thread engagement and hub-centric location. Recalculate effective offset in the tool.
If any OEM values are unknown for your exact trim, confirm through the owner’s manual or a GM parts department using your VIN, then finalize with the calculator.
Installation Tips
- Test fit each wheel without the tire first to verify caliper and hub fit. Confirm that the wheel seats fully on the hub.
- Clean the hub face and the wheel mounting pad. Remove rust and debris to prevent runout and vibration.
- Use hub-centric rings when the wheel center bore is larger than 67.0 mm. Rings should be heat resistant and seat flush.
- Hand-thread lug nuts and tighten in a star pattern. Final torque to the OEM spec from Cadillac service information.
- If using spacers, ensure proper hub-centric design and sufficient thread engagement. Recheck torque after installation.
- After road testing, re-torque the lug nuts after 50 to 100 miles and recheck for any rubbing at full steering lock and over bumps.
- Schedule an alignment if you changed wheel width or tire profile to maintain even wear and correct handling.
Tools And Helpful Supplies
Also have a floor jack, jack stands, a wire brush for hub cleaning, anti-seize for the hub face if recommended by your shop, and a quality tire pressure gauge.
FAQs
Does the 2010 Cadillac CTS-V use 5x120 or 5x120.65?
For this model, the provided OEM bolt pattern is 5x120. Always verify by VIN or with a trusted parts source if you suspect prior hub or brake swaps.
Is the car hub-centric or lug-centric?
The CTS-V hub bore listed is 67.0 mm. Use wheels that are hub-centric to 67.0 mm, or install quality hub-centric rings if the wheel bore is larger.
Can I run spacers on a CTS-V?
Spacers can be used to correct clearance, but they change effective offset. Model the spacer thickness in the calculator, ensure proper hub-centric engagement, and maintain adequate thread engagement. Follow professional installation practices.
What tire size keeps my speedometer closest to stock if I change rim diameter?
Use the calculator. When you change rim diameter, adjust the tire’s aspect ratio and section width so overall diameter remains close to the OEM 255/40R19 result. Many installers aim to stay within about 3 percent of stock diameter.
Do I need new TPMS sensors?
If reusing your existing sensors is not possible, use compatible sensors for your 2010 CTS-V and perform the relearn. A GM TPMS relearn tool simplifies this process.
What lug nut seat type should I use?
Match the seat style to the wheel manufacturer’s specification, while keeping the OEM thread size M14 x 1.5. Do not mix seat types.
What torque should I use on the lug nuts?
Follow the factory torque specification in the owner’s manual or GM service information. Do not rely on generic values. Re-torque after initial miles.
How do I check brake caliper clearance?
Use the calculator to screen offset and width, then physically test fit. Inspect spoke-to-caliper and barrel-to-caliper clearance throughout one full rotation.
