Expert Buying Guide for 2005 GMC Savana 2500 Cargo
For the 2005 GMC Savana 2500 Cargo, the 8x165.1 bolt pattern is used, but the center bore is a critical 116.7mm. Aftermarket wheels often have a larger bore, requiring hub-centric rings to prevent vibration and ensure proper load distribution. The offset is sensitive; stick to 28mm ±5mm to avoid rubbing or clearance issues. Always use the correct 14x1.5 lug nuts with a cone seat—ball seat nuts can loosen and cause wheel separation. Re-torque after 50-100 miles. Wheels from 1996-2010 Savana 2500 models are direct fit, but avoid 8x180 pattern wheels from later years.
