Expert Buying Guide for 2002 GMC Savana 1500 Cargo
For your 2002 GMC Savana 1500 Cargo, the 6x139.7 bolt pattern and 78.1mm center bore are critical. Aftermarket wheels often have a larger center bore (e.g., 108mm), requiring hub-centric rings to prevent vibration and ensure proper load transfer. Offset must stay within 20-30mm; deviations risk rubbing on suspension or fenders. Always use lug nuts with the correct 14x1.5 thread pitch and matching seat (cone or ball) to avoid loosening. Re-torque after 50-100 miles. Wheels from 1996-2014 Savana 1500 models are direct fit.
