Expert Buying Guide for 2009 Cadillac CTS
For your 2009 Cadillac CTS, the bolt pattern is 5x120.65, a spec shared with 2009-2019 CTS models. The center bore is 67.1mm; aftermarket wheels with a larger bore require hub-centric rings to prevent vibration. Offset is critical: stock is 50mm; deviations affect handling and may cause rubbing. Always use lug nuts with the correct thread pitch (12x1.50) and seat type (conical/60-degree). Never use ball-seat lug nuts. Ensure proper torque (140 Nm) and re-torque after 50 miles. Avoid wheels from 2008 CTS (5x115).
