Expert Buying Guide for 2017 Cadillac CT6
When selecting aftermarket wheels for your 2017 Cadillac CT6, the 67.1mm center bore is critical. Most aftermarket wheels have a larger bore (e.g., 72.6mm), requiring hub-centric rings to prevent vibrations and ensure proper load distribution. The factory offset is 32mm; deviations beyond ±5mm may cause rubbing or clearance issues. Always verify lug nut compatibility: the CT6 uses 14x1.50 thread pitch with a conical (60-degree) seat. Using incorrect lug nuts (e.g., ball seat or wrong thread) can lead to wheel detachment. For a safe fitment, prioritize wheels with the correct bore, offset within range, and proper lug hardware.

What other years of Cadillac CT6 have the same bolt pattern as the 2017?
The Cadillac CT6 uses the 5x120.65 pattern from 2016 through 2019. Wheels from any of these model years are dimensionally compatible with the 2017, provided the offset and center bore also match.
How do I measure the bolt pattern on my 2017 Cadillac?
The 2017 CT6 uses a 5x120.65 pattern. For 4, 6, or 8-lug wheels, measure center-to-center across opposite holes. For 5-lug, measure from the center of one hole to the back of the opposite hole.
Why is matching the 67.1mm center bore important for the 2017 CT6?
The 67.1mm center bore ensures the wheel is perfectly centered on the hub. If the wheel is lug-centric instead of hub-centric, you may experience steering wheel vibration at highway speeds.
Will wheels from another Cadillac fit my 2017 CT6?
Only if they share the exact same 5x120.65 bolt pattern, a compatible offset, and a center bore equal to or larger than 67.1mm.
How tight should I torque the lug nuts on a 2017 Cadillac CT6?
Refer to your owner's manual for exact specs, but always tighten the N 14x1.50 hardware in a star or crisscross pattern. Re-torque after the first 50 miles of driving.
