The values below reflect information supplied for this specific page. They may represent one factory package or a partial data set. Wheel and tire specifications can vary by trim, brake package, and regional option. Always verify against your door-jamb placard, the owner’s manual, or your VIN at an OEM parts desk.

| Aspect ratio | 55 |
| Rim diameter | R18 |
Note: The provided tire size 235/55R18 and wheel size 20x9 ET35 are not a matched set. This often indicates multiple OEM wheel-tire packages existed for the model year. Use the on-page calculator and cross-check your specific vehicle’s door placard and OEM documentation to confirm what your car was delivered with.
The calculator on wheelinterchange.com lets you safely compare a donor wheel setup to your 2013 Cadillac XTS.
The dataset for this page shows at least one OEM 20-inch wheel spec and one OEM 18-inch tire spec for the 2013 Cadillac XTS, which suggests multiple factory packages existed. If you plan to plus-size or downsize:
What is the bolt pattern for the 2013 Cadillac XTS?
5x120 according to the provided data. Confirm on your specific trim before ordering wheels.
What center bore do I need?
66.9 mm is listed for this model year. If the aftermarket wheel has a larger bore, use hub-centric rings sized to 66.9 mm. A smaller bore will not fit.
What is the correct lug thread?
M12 x 1.5. Match the lug nut seat type to the wheel design.
Which wheel and tire sizes are OEM?
This page shows a 20x9 ET35 wheel and a 235/55R18 tire, which are not a matched set. That indicates multiple OEM packages may exist. Check your door-jamb placard and the owner’s manual, or verify by VIN with a Cadillac parts department.
Will wheels from another 5x120 vehicle fit my XTS?
Not automatically. In addition to 5x120, you must match or properly adapt center bore, offset, brake clearance, load rating, and hardware. Use the calculator to compare and always perform a test fit.
What offset range works on the 2013 XTS?
This varies by wheel width and brake package. Use the known OEM reference in the calculator and adjust width and offset to maintain safe inner and outer clearances. Verify with a physical test fit.
Can I run an 18-inch winter setup?
The data suggests at least one OEM 18-inch tire size existed for this model year. Brake clearance can vary by trim, so confirm with your specific car using the calculator and a test fit, and verify against OEM documentation.
Do I need new TPMS sensors for new wheels?
You can often reuse or source compatible sensors, but part numbers and frequencies must match your vehicle. After installation, perform the TPMS relearn procedure as specified by Cadillac.
What torque should I use on the lug nuts?
Refer to the Cadillac service manual or your door-jamb information for the correct torque for your trim. Use a torque wrench and re-check torque after a short drive.
Use the calculator on wheelinterchange.com and OEM sources to confirm any values that are not listed or that may vary by trim.
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.
