Expert Buying Guide for 2019 Cadillac CT6-V
For the 2019 Cadillac CT6-V, the bolt pattern is 5x120.65 (unique to this year; 2020+ uses 5x120). The center bore is 67.1mm—critical for hub-centric fitment. Aftermarket wheels often have a larger bore; use hub-centric rings to avoid vibration. Offset is sensitive: stock is ~32mm; deviations affect clearance and handling. Always verify lug nut thread pitch (14x1.50) and seat type (cone or ball). Incorrect lug nuts can cause wheel loss. Re-torque after 50-100 miles. Avoid wheels designed for 5x120 without proper adapters.
