Expert Buying Guide for 2008 Buick Lucerne
For your 2008 Buick Lucerne, the bolt pattern is 5x115 with a center bore of 70.3mm. When selecting aftermarket wheels, ensure the center bore matches or use hub-centric rings to prevent vibration and ensure proper load distribution. The offset range is 40-50mm; staying within this range maintains suspension geometry and prevents rubbing. Always use M12x1.5 lug nuts with the correct seat type (cone or ball seat) to match the wheel. Improper lug nuts can cause wheel loosening.
