OEM wheel and tire fitment specs for the 2010 Cadillac CTS, including bolt pattern (PCD), center bore diameter, thread size, rim diameter, rim width, wheel offset, and backspacing.
Recorded OEM specifications for the 2010 Cadillac CTS, donor years with overlapping ranges, and a calculator to compare a selected wheel. Range overlap is not a guaranteed fit.
Multiple OEM configurations exist for this vehicle. Fitment can vary by trim, brakes, and factory wheel package – confirm your exact setup before buying.
Center-bore records disagree: year-level hub 67 mm vs trim range 66.9–66.9 mm. Interchange below does not treat this as an unqualified match.

Donor vehicles with overlapping OEM specs
These are vehicle-year records whose recorded OEM ranges overlap this 2010 Cadillac CTS. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 46 donor years. Listed 24 eligible overlaps (not all evaluated years are compatible). Showing all listed.

Wheel geometryOEM width/offset ranges overlap (not a specific wheel)
Recorded vehicle-side thread for the 2010 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.

Center-bore records disagree (target year-level hub 67 mm vs trim range 66.9–66.9 mm; donor year-level hub 67 mm vs trim range 66.9–66.9 mm). Unqualified overlap is not claimed until the conflict is resolved.

How To Use The Wheel Interchange Calculator
The calculator lets you compare a donor wheel and tire setup to your 2010 Cadillac CTS and preview clearance, ride height, and speedometer impact.
Step 1. In Wheels from donor vehicle, enter the wheel and tire specs from the vehicle or wheels you want to install. If you only have wheel size, use Custom wheel size and leave the tire fields blank.
Step 2. In Installed on your vehicle, select 2010 Cadillac CTS and enter your current wheel and tire sizes. If you are not sure, read your tire sidewall and door-jamb sticker.
Step 3. Use Custom wheel size to test different rim width, diameter, and offset. The tool will show inner clearance change and outer poke vs your current setup.
Step 4. Use Custom tire size to adjust section width and aspect ratio. The total tire diameter will update so you can keep overall diameter close to stock.
Step 5. Review the results for inner clearance to strut and knuckle, outer fender poke, speedometer change, and ride height change.
Step 6. If any measurement goes negative or shows interference risk, reduce width, increase positive offset, or choose a tire with a smaller section width. Recalculate until you have safe clearances.
Step 7. Before buying, confirm bolt pattern 5x120, center bore 67.0 mm, and thread size M14x1.5 from the tables above and your OEM sources.
Fitment Checklist Before You Buy
Bolt pattern: Wheel must be 5x120. Adapters change geometry and are not recommended unless professionally specified.
Center bore: OEM hub is 67.0 mm. Aftermarket wheels with a larger bore require hub-centric rings sized to 67.0 mm inner. Do not use wheels with a smaller bore.
Thread size and seat: Lugs are M14x1.5. Verify the lug seat type that matches your wheel design before purchase.
Offset and width: Use the calculator to ensure inner clearance to strut, spring perch, and brake lines, and that outer poke does not contact the fender or liner.
Overall tire diameter: Keep total diameter close to your OEM combo to protect ABS, traction control, and speedometer accuracy. Many owners target within about 3 percent.
Load and speed ratings: Replacement tires must meet or exceed the OEM load index and speed rating printed on your door-jamb sticker.
Brake clearance: Some trims and brake packages need specific barrel clearance. Visually test-fit wheels over the front calipers before mounting tires.
TPMS: Plan for compatible TPMS sensors or re-use and re-program your originals.
Spacers: Only if required for caliper clearance and after verifying stud engagement and fender clearance. Professional inspection recommended.
Plus Sizing And Common Upgrades
Plus sizing trades sidewall height for larger wheel diameter. To plan a plus size safely for your 2010 Cadillac CTS:
Start from your actual current tire size. If your door sticker or current tires differ from the sizes listed above, use those as your baseline.
Use the calculator to increase rim diameter in 1 inch steps while adjusting tire aspect ratio so overall diameter stays close to stock.
Wider wheels usually require lower offsets to avoid inner rubbing, but too little offset can cause fender contact. Adjust width and offset together in the calculator until inner and outer clearances are positive.
Staggered setups can affect tire rotation and stability control tuning. If considering staggered widths, compare both front and rear in the tool and match overall diameters side to side.
Winter downsizing: Many owners choose a smaller rim with a taller tire for winter to improve compliance. Verify brake clearance and keep overall diameter similar with the calculator before buying.
Installation Tips
Dry-fit first: Test a bare wheel on the front hub to confirm caliper and hub-lip clearance before mounting tires.
Clean mating surfaces: Remove rust from the hub face and the wheel mounting pad. Any debris can cause runout or loosening.
Hub-centric rings: If your wheel bore is larger than 67.0 mm, install proper rings so the wheel centers on the hub.
Lug hardware: Use the correct M14x1.5 nuts or bolts with the proper seat type for your wheels. Do not lubricate studs or seats unless the OEM procedure specifies it.
Torque and pattern: Tighten in a star pattern in stages using a calibrated torque wrench. Use the factory torque spec from your owner’s manual or dealer.
Retorque: Recheck torque after 50 to 100 miles of driving.
TPMS: Install compatible sensors and complete relearn per the owner’s manual.
What is the bolt pattern for the 2010 Cadillac CTS?
5x120. Any replacement wheel must match this pattern unless a professionally engineered adapter system is used.
What center bore do I need?
The hub bore is 67.0 mm. Wheels with a larger bore will need hub-centric rings sized to 67.0 mm inner. Wheels with a smaller bore will not fit.
Which lug nuts does it use?
Threads are M14x1.5. Confirm the correct seat type for your specific wheels before purchasing hardware.
Will 18x8 ET48 wheels fit my CTS?
An 18x8 with ET48 and about 5.89 in backspacing is a known OEM configuration. If your brakes or suspension differ, verify clearances with the calculator and a physical test-fit.
My sticker shows a different tire size than above. Which is correct?
Use the size on your door-jamb sticker and what is currently on your car as your baseline. Factory equipment can vary by trim. Enter your exact size into the calculator for accurate comparisons.
How close should my new tire diameter be to stock?
Many installers target within about 3 percent of the original overall diameter to keep speedometer and driver-assist systems happy. Use the calculator to check.
Do I need spacers for aftermarket wheels?
Only if required for caliper or strut clearance after confirming with measurements. Spacers affect stud engagement and fender clearance. If used, choose high quality parts and have them inspected by a professional.
Can I run a staggered setup?
Possibly, but verify both front and rear clearances and keep left and right overall diameters equal. Consider rotation limitations and tire availability before purchase.
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.
