Expert Buying Guide for 1998 GMC Savana 2500 Passenger
For your 1998 GMC Savana 2500 Passenger, the 8x165.1 bolt pattern is shared with 1996–2010 models. The center bore is 116.7mm—critical for hub-centric fitment. Aftermarket wheels often have a larger bore; use hub-centric rings to avoid vibration. Offset is sensitive; the factory 28mm offset ensures proper clearance. Using wheels with significantly different offset can cause rubbing or bearing stress. Always use the correct 14x1.5 lug nuts with the proper seat (cone or ball) to prevent loosening. Never use incorrect thread pitch or seat type; it compromises safety.
