Expert Buying Guide for 2016 Cadillac CT6
The 2016 Cadillac CT6 uses a 5x120.65 bolt pattern with a 67.1mm center bore. When selecting aftermarket wheels, hub-centric rings are mandatory to ensure proper centering and prevent vibrations. The factory offset is 32mm; deviations beyond ±5mm may cause rubbing or clearance issues. Always verify lug nut compatibility: the CT6 requires 14x1.50 thread pitch with a conical (60-degree) seat. Using incorrect lug nuts can lead to wheel separation. For safety, avoid ball-seat or shank-style lug nuts. Re-torque wheels after 50-100 miles of driving to maintain clamping force.
