Expert Buying Guide for 2008 GMC Savana 3500 Passenger
For your 2008 GMC Savana 3500 Passenger, the bolt pattern is 8x165.1mm with a critical center bore of 116.7mm. Aftermarket wheels often have a larger bore, requiring hub-centric rings to prevent vibration and ensure proper load distribution. The offset range is sensitive; stick to 28mm ±5mm to avoid rubbing or suspension interference. Always use the correct lug nuts: 14x1.5 thread pitch with a conical (60-degree) seat. Never use ball-seat lug nuts, as they can loosen. Re-torque after 50-100 miles. Wheels from 1996-2010 Savana 3500 models are direct fit.
