Expert Buying Guide for 1996 Buick Century
For your 1996 Buick Century, the 5x115 bolt pattern is shared with 1992–2005 models. The 70.3mm center bore is critical: aftermarket wheels with larger bores require hub-centric rings to prevent vibration and ensure proper load transfer. Offset is sensitive—stick to 45mm ±5mm to avoid rubbing or clearance issues. Always use lug nuts with the correct thread pitch (12x1.50) and seat type (conical/60-degree). Ball-seat or incorrect pitch nuts can cause wheel loosening. Re-torque after 50 miles of driving.
