Expert Buying Guide for 2004 GMC Savana 2500 Passenger
For your 2004 GMC Savana 2500 Passenger, the 8x165.1 bolt pattern is shared with 1996–2010 models. The critical center bore is 116.7mm; aftermarket wheels often have a larger bore, requiring hub-centric rings to prevent vibration and ensure proper load transfer. Offset is sensitive: the factory 28mm offset maintains correct scrub radius and clearance. Deviating more than ±10mm may cause rubbing or handling issues. Always use 14x1.5 lug nuts with the correct seat type (conical or ball) matching the wheel. Improper seating can lead to loosening. Re-torque after 50–100 miles.
