These are vehicle-year records whose recorded OEM ranges overlap this 2007 Cadillac CTS-V. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 13 donor years. Listed 13 eligible overlaps (not all evaluated years are compatible). Showing all listed.
Years grouped because recorded compatibility evidence is equivalent. Each year keeps its own page.
Approximate position vs the mid OEM package: outer change -1.17 mm, inner change -5.18 mm. This uses aggregated width/offset ranges, not a specific wheel.

The specs below reflect known factory equipment for the 2007 Cadillac CTS-V. If a detail is not listed, confirm it in your owner’s manual or with a GM dealer before purchasing wheels or tires.
| Spec | Value | Notes |
|---|---|---|
| Bolt pattern | 6x115 | 6 studs, 115 mm pitch circle diameter. Must match exactly. |
| Center bore | 70.3 mm | Use hub-centric rings if aftermarket wheel bore is larger. |
| Thread size | M12 x 1.5 | Verify lug nut seat type for your wheels before purchase. |
| Wheel size | 18 x 8.5 in | Factory rim diameter and width. |
| Wheel offset | ET 48 mm | Positive offset. Keep scrub radius and clearance in mind when changing. |
| Backspacing | 6.14 in | Provided value. Compare in the calculator when changing wheel width or offset. |
| Tire size | 245/45R18 | Approx overall diameter about 26.7 in, section width ~245 mm. |
Torque specs, lug nut seat style, TPMS details, and brake package clearances can vary. Always verify these with OEM documentation for your exact VIN.
The on-page calculator lets you compare a donor wheel and tire setup to your 2007 CTS-V, and also try a custom size. It updates tire diameter automatically when you change rim diameter.
Many CTS-V owners explore plus sizing to improve handling or appearance. Popular routes include:
Because offset needs depend on exact wheel width, tire model, and suspension ride height, confirm every change with the calculator and a physical test fit. If a spec is not listed above, verify with OEM documentation.
What is the bolt pattern on the 2007 Cadillac CTS-V?
6x115. Wheels with any other PCD will not seat correctly and should not be used.
Can I use 6x114.3 wheels on a 6x115 CTS-V?
No. The stud circle is different. Even small PCD mismatches are unsafe.
Do I need hub-centric rings?
If the aftermarket wheel’s center bore is larger than 70.3 mm, use rings to center the wheel on the hub. If the wheel bore is 70.3 mm, rings are not needed. A wheel with a smaller bore will not fit.
What tire diameter should I target?
The OEM 245/45R18 is about 26.7 inches in overall diameter. Keep new setups close to this to protect ABS and speedometer accuracy. Use the calculator to check percentage change.
What offset range can I run?
The factory offset is ET 48 mm. Safe alternatives depend on your chosen wheel width, tire model, and ride height. Use the calculator to compare inner and outer clearance to OEM, then perform a physical test fit.
What is the correct lug nut torque?
Refer to the Cadillac owner’s manual or GM service manual for your exact torque spec. Do not guess. Re-torque after 50 to 100 miles.
Will big brake kits fit behind smaller diameter wheels?
Clearance depends on the brake kit and wheel design. Always check with a template from the brake or wheel manufacturer and verify with a test fit.
Can I run spacers on the CTS-V?
Possibly, but use hub-centric spacers that maintain a 70.3 mm pilot and ensure proper stud engagement. Check local regulations and re-torque regularly.
Do I need new TPMS sensors?
If reusing OEM wheels and sensors, you may be able to transfer them. Sensor frequency and style can vary. Confirm compatibility by VIN and follow GM relearn procedures.
Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:
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.
