Expert Buying Guide for 1996 GMC Savana 1500 Passenger
When selecting wheels for your 1996 GMC Savana 1500 Passenger, the 6x139.7 bolt pattern is shared with 1996–2014 models, ensuring broad compatibility. Critical to proper fitment is the 78.1mm center bore; aftermarket wheels often have a larger bore, requiring hub-centric rings to prevent vibration and load stress. Offset must stay within 20–30mm; deviations risk rubbing or bearing damage. Always use lug nuts with the correct 14x1.5 thread pitch and matching seat type (cone or ball) to avoid loosening. Verify wheel load rating meets or exceeds OEM specs for safety.
