Expert Buying Guide for 2004 GMC Savana 2500 Cargo
For your 2004 GMC Savana 2500 Cargo, the 8x165.1 bolt pattern is shared with 1996–2010 models. The 116.7mm center bore is critical: aftermarket wheels often have a larger bore, requiring hub-centric rings to prevent vibration and ensure load is on the hub, not the lugs. Offset is sensitive; stock is 28mm. Sticking close to this range maintains steering geometry and prevents rubbing. Always use 14x1.5 lug nuts with the correct seat (cone or ball) matching the wheel. Improper seating can cause loosening. Re-torque after 50-100 miles.
